Unbreakable Fire Zone

As touched on earlier this year, Manny Diaz makes a great point when he says that his fire zone “is the safest thing I can run”. Coupled with pattern-match principles it allows the defense to congeal itself into whatever form the offense runs like a veritable coverage jiu jitsu.

 
The point of this post will be to illustrate the flexibility the concept provides where most blitzes would ‘break’ or require a check out of. We will concentrate on how coverage defenders should respond to challenging patterns from typically stressful formations of 1-back and empty. This is an element that we enjoy discussing here; the evolution and adaptations within the game of football.

 
The key to the success of this type of defensive application remains the teaching methodology that carries concepts over from Cover 1, to Cover 3 pattern match, to Rip/Liz match. The combination of these fundamentals are what the success of the fire zone is built upon. Neglecting or not thoroughly teaching the roles will limit the effectiveness of how players operate within the fire zone.



For the sake of discussion, we’ll narrow the application to the “NCAA Blitz” fire zone that everyone runs, but keep in mind, just plug-and-play personnel groupings because it’s all relative regardless if it is a safety, backer, or lineman taking on the role of one of the underneath defenders. For the sake of clarity in this review, terminology varies from staff to staff, but I will refer to the wall/flat player as the ”SCIF” player and the middle hole/hook player as the “final 3rd” defender.

 
As we’ve discussed before, any defense can line up against 2-back pro formation, it’s what the defense has to become when confronted by 2x2 or 3x1 sets that determines what the defense actually is.

 
The best way to conceptualize the coverage matching is that you will zone into the pressure / man (match) away from the blitz.

 
2 x 2

With the fire zone you’re essentially getting 3-deep coverage, a seam player, and one final defender to match the third receiver to either side (or cut any crossers). Because 2x2 is one-back and essentially a ‘spread’ set, the Rip/Liz check becomes the standard way to aggressively handle the two seam receivers. Instead of passing off receivers or spot-dropping, letting voids develop – this method ensures the routes will be accounted for while still avoiding the inflexibility of true man coverage.


How the remaining back will be accounted for is all that really differs from Cover 3. This also plays into how shallow crossers will be handled (with inside verticals compensated with Rip/Liz). Without the ability to funnel the back between two linebackers, you only have one backer (and lose the ability to ROBOT away inside routes). This essentially has the middle hole player assigned to aggressively match the back (who is #3 receiver to whichever side he releases).

2x2 out of a 3-deep concept (fire zone) will be handled simply by Rip/Liz in all cases. This remains true unless a receiver immediately breaks inside under 5 yards. With inside breaking routes, the defenders will not chase but alert the final 3rd player that he has a route approaching (“cut” as the hole defender). The final 3rd defender will receive an “UNDER” call from one of the outside defenders (an inside breaking route under 5 yards). This is a post-snap call on Rip/Liz to zone off into a 3 deep principle (#1 or #2 takes route inside).



Typically with a shallow, it is paired with a back flaring to the side of the field where the shallow originated to serve as an outlet receiver. This makes for an easy exchange, just like a “rat” call in Cover 1. The SCIF and final 3rd player just replace one another’s receiver, though the distribution remains consistent (the shallow becomes the 3rd route, the flare is the 2nd route, and the post is the 1st route in the distribution).



A more challenging route package for matching would feature the shallow to the same side as the flare. In this example, both SCIF players would carry #2 vertical with the Rip/Liz rules and the final 3rd player would pick up and carry the crosser after receiving the UNDER alert. With all threats leaving his area, the away-side corner would sink and high-leverage the dig route.

 
3 x 1

Trips formations can be a bit more challenging to the fire zone because it can immediately out-leverage defenders by alignment (3 receiver side). Even though it presents a horizontal stretch, the 3 receiver set can be handled using the same method as the zone-push concept, “Mable”. The first outside receiver would be manned by the corner. The second and third receivers will be (banjo) matched by the SCIF and final 3rd player underneath with the corner to trips manning on the #1 receiver. The away-side SCIF player would immediately look to match the back or whoever became the #4 receiver in the route distribution.



Here, just like in 2x2, the shallow by X precipitates an UNDER call by the corner letting the final 3rd player know he has a receiver crossing the formation (becoming the 3rd receiver / 1st receiver inside to trips) to cut. The away side corner would high-shoulder squeeze the shallow into the formation until picking up the (meshing) drag by Y. This leaves the away-side SCIF player free to jump the back releasing to his side.



The previous two examples showed #2 in the trips being the first underneath out route. What happens if #2 releases inside (such as with spacing shown here)? The H receiver would become the first receiver inside, with the Y being the first receiver outside. Since the H is no longer the #2 route in the distribution, he is passed off to the final 3rd player. The SCIF player matches the Y as the first of these two ‘outside’ underneath.



Empty



With empty, the only check required would to be ensure that the rush is coming away from the 3-man surface due to leverage issues. With two receivers away from trips essentially in man coverage and zoning to the trips, it would require the zone defenders to the trips side to be afforded the best possible positioning on the two inside receivers (just flipping where the overload is coming from).  Just like against any trips set, the trips-side defenders would Mable (zone push) into the route dispersion. The away-side would aggressively man the remaining 2 receivers and retain the middle-of-the-field safety.

Nick Saban: Cover 3 Adaptation (Rip/Liz) To The Spread

After providing an overview of playing Cover 3 with pattern-matching principles, we'll now take a look at the adaptations utilized to strengthen this basic concept.

A mantra comically repeated within the circles of "Air Raid" offenses is, "everything works against Cover 3", meaning whatever the concept, you can pass at will against most cover 3 defenses. With natural voids in the defense in the flats and in the seams, the four underneath defenders are typically the lynch pin of how successful a cover 3 defense will be.

The easiest threat to victimize cover 3 is the #2 receiver in the seam. The defense must be able to account for this threat or it will spend much of the game seeing the free safety 'wrong' on a 4 vertical threat.

and so the chess match, begins
To accommodate for this deficiency, Saban's defenses have evolved through the last decade with a "Rip/Liz" match based on where the safety drops into the box (Rita / Linda) against the 2 quick threat (2x2).

From Coach Saban, himself

When you’re playing a passing team you always have a better chance with split-safeties, but with all this zone read / zone option stuff we see…all the spread stuff, sometimes you’ve got to be able to play middle-of-the-field coverage to get an extra guy in the box.


We got to the point where, this is the reason that we do this, when everybody started going spread we couldn’t play 3 deep zone. This started with the Cleveland Browns, I was the defensive coordinator in the early 90s and Pittsburgh would run 'Seattle' on us , four streaks. Then they would run two streaks and two out routes, what I call ‘pole’ route from 2x2. So we got to where could NOT play 3-deep zone because we rerouted the seams and played zone, and what I call “Country Cover 3” (drop to your spot reroute the seams, break on the ball). Well , when Marino is throwing it, that old break on the ball shit don’t work.

So because we could not defend this, we could not play 3 deep, so when you can’t play zone, what do you do next? You play Man (cover 1), but if their mens are better than your mens, you can’t play cover 1 .


We got to where we couldn’t run cover 1 - So now we can’t play an 8 man front.
The 1994 Browns went 13-5 , we lost to Steelers 3 times, lost 5 games total (twice in the regular season, once in the playoffs). We gave up the 5th fewest points in the history of the NFL, and lost to Steelers because we could not play 8-man fronts to stop the run because they would wear us out throwing it

We came up with this concept; how we can play cover 1 and cover 3 at the same time, so we can do both these things and one thing would complement the other. We came up with the concept “rip/liz match”.


The "Rip" / "Liz" call will alert the OLB to the call side that he has a safety coming down who will be assuming the Curl/Flat responsibilities. With the Rip/Liz declaration, the backers away from the call will alert to "Match" ("Rip - Match Left") their quick away from the call, and how the corner to his side will match their receivers. It is all premised on controlling #2 deep in the seam, by catching and carrying #2 vertical or outside past 12-15 yards (this should start sounding familiar to BRONCO/SCIF technique). If there is no threat of 2 verticals to a side, it really becomes your standard fare Cover 3. If #2 crosses / goes inside, he communicates with an "Under" call (alerting the backers inside to cut the receiver) and turns his focus to rob #1 underneath (like standard Curl/Flat Cover 3, robbing inside and underneath #1).
It is essentially saying to the corners and C/F player, "versus two quicks, we're man-to-man all the way, unless our guys breaks inside". The communication is the vital part of the equation. Because the defense is presenting a 2-high shell, you could be playing a Cover 2, 4, 7, or 8 concept, but when you drop the safety down, you have to have a fast and efficient way to communicate which safety is dropping and how the backers away from the drop will respectively handle their threats.

Worst case scenario in Cover 3 is the 4-verticals concept (4 receiver on 3 deep defenders). Rip/Liz match specifically handles this. If you accommodate for 4 verts, you aren't left with many other issues that can hurt you because you will still have 6 in the box. Getting down to brass tacks, lets review how this concept fleshes itself out.

If #1 is vertical and #2 is vertical (VERTICALS)


#1 presses vertical, the corner takes all of #1 - #2 presses vertical, the C/F players takes all of #2
The inside linebackers will match #3 as he presents himself, looking to expand from the hook zone. By carrying the two inside verticals, remember you still have a middle of the field safety, so the backer/safety carrying #2 can maintain a low-shoulder, outside leverage on the receiver. This puts him in great position to discourage the SAIL (or 'pole') deep out break of #2 if it were to develop (past 12-15 yards).

If #1 is vertical and #2 is outside (SMASH)

Looking at the quick game smash concept (backside 5-step check), you can see how this is handled. #1 into the smash (right side of the diagram) takes all of #1 because he hasn't stemmed inside ("under" call, remember) and the C/F match player here handles all of #2 (vertical-outside). On the backside (here the 'rip' adjustment ~ left of the diagram), #1 stems vertical, so the corner matches all of #1. The #2 receiver runs a speed out, so the safety takes him man-to-man.

If #1 is inside and #2 is vertical (DRIVE)

Now a little tricky, the backside match (left diagram, away from 'liz'), has #1 immediately inside on a shallow, so the corner can sink and be over the top of #2, who is running a vertical (past 12 yards) stem into a dig. Because #2 is not inside ("Under"), the C/F safety matches #2 outside and underneath. With the shallow by #1, the backside inside linebacker is looking to cut the crosser (X) and the nearside inside linebacker will ROBOT the dig (depth and rob underneath).

If #1 is vertical and #2 is inside (SHALLOW)

Here, you see (right side of diagram) the match principle of the backer does NOT have a vertical stem of #2, so he declares the "Under" call, alerting the backers to ROBOT and CUT, as he will play standard Cover 3 curl-to-flat rules (with not threat to the seam), gaining depth and width (underneath #1 to his side).

If #1 is inside and #2 is inside (QUICKS / YOGI strong flood)

With the vertical stem of #2 (right side of diagram) the C/F match player carries him and since he is playing outside-underneath leverage, can easily take all of #2 with the outside break. With #1 vertical, the corner can match all of #1, as he would on a vertical #1 in Cover 3. The nuance here is that #3 is immediately releasing to the flat. The inside linebacker to flow (M) can be the final 3 player as there was no "Under" call. This eliminates the easy flood against Cover 3 (and remains consistent with Cover 4 rules and SCIF/Bronco rules).

"Rip/Liz" is an adaptation of 3 Deep zone. How the corners and backer/safety support is primarily a game plan adjustment and can be tweaked on how your opponent actually uses 2x2 route packages. Now, you may be saying, "thats all well and good, but what about trips and empty"? Right, that will be up next, when we explore Saban's "mable" adjustment to Trips/Trey formations.

UPDATE: Be sure to check out the 'breakout' session in the comments section below. Also, the adjustment to 3x1 "Mable" is located here. In addition, here is the only film representation of Rip/Liz I could find (outside of a broadcast) of the safety spin, Cover 3, versus 2x2. It doesn't represent the pattern match well because it was a bubble screen, but you can pick up on the fits, backer response, and leverage of the C/F players



FYI - I will update THIS POST with coverage cutups soon, illustrating this being used in game situations. Much respect to my guy, Chris Vasseur, for helping me flesh out the details here and who is also running this with the program he's at now. Also, to coach Chip Bilderback, who's contributions to providing Saban's adapations have proven invaluable.


This blog is primarily just a way of sharing and exchanging coaching information; just trying to pass along nuggets that may help you and your team. Handling spread is an interesting task, and this was one way of adapting a 1-high defense to meet the needs of a threat. Next, we'll take a look at a defensive coordinator's other option for handling the spread, by going into detail of Gary Patterson's TCU "2 Read" handling 4-verticals.

TCU "2 Read": Adaptation To The Spread (2x2)

While exploring the defensive adaptations to offensive trends towards "the spread" (Va Tech in the 90s / Saban Cover 3 adjustments ), and not intending to repeat any of the fantastic coverage of TCU defensive tenets done at Run COD Hit, it would behoove us to at least go over how TCU would confront 2x2 / 3x1 formations out of their base split-field coverage, '2 read'.

TCU's 42 defense is based out of Cover 2 "Read", which is really just a robber + quarters read out of a MOFC look. TCU will typically not play ‘2 Read’ against any 1-back look (preferring Blue or Cover 5), so what we are presenting is just a ‘worse-case’ scenario against this coverage.

Since they are splitting the formation in half, they are just reducing the concept down to the 1, 2, or 3 receiver matching. Just like the Rip/Liz adjustment covered before, when facing a balanced 2x2 formation, the secondary would have to declare which side they are going to play as the 'read side' (where the FS will be robbing). If '2 Read' is called, versus a 2x1 formation, the FS would naturally rob the receiving strength (2 receiver side). With 2x2, you would have to declare "reading left" to communicate the 'read side' and the 'away side', alerting the away safety on how he will handle #2. To the 'read side', this is how zone distribution would essentially play out in a nutshell.

"2 Read" is the base coverage TCU bases out of (it really is just robber). They may not even run this coverage much after installation, but it remains the elementary foundation for all subsequent variations regularly employed.

To get down to brass tacks, the rules are relatively simple and outlined below:

"2 Read" is the base coverage TCU bases out of (it really is just robber). They may not even run this coverage much after installation, but it remains the elementary foundation for all subsequent variations regularly employed.

To get down to brass tacks, the rules are relatively simple and outlined below:

Read Left

  • Read side Corner- 1x7 match deep vertical threat
  • Strong (read) Safety - 5x1 force on run / pass read: open to flat "swing deep to 3"
  • Free Safety- alley fit on run / pass use 'Robber rule' - vertical by #2 / no vertical by 2, rob curl-to-post of #1
  • Strong Backer -match #2 - #3
  • Weak Backer - match #2 weak vertical
  • Weak (away) Safety -run force / pass curl-flat "swing deep to 2"
  • Away side Corner-deep 1/2 (over post of #1)

Read Side Communication

Corner is 1x7 in press bail shuffle with a man-clue of the #1 receiver. Corners always 1x7 unless #1 receiver is outside of numbers (they never cross the numbers in robber). Corners always play inside leverage, always protecting the post (because you don’t know if you’re going to get help from the FS). The post-snap cushion is not enforced, and in fact, Patterson wants receivers to break the defender’s cushion so he’ll only have to play one side now. If there is only one receiver split, the corner will man-turn into the route. If there is more than one receiver split, he will zone-turn into the route. Because this is a robber concept, the corners are taught to make the post a priority and, if necessary, align as much as 4 yards inside the receiver to protect the middle of the defense. With these rules, Patterson essentially invites offenses to run the post-corner because he feels he can take everything else away and force this difficult throw. To get the most out of this coverage, a pattern-match communication system is utilized to hasten how the 3 key defenders respond. The corner will communicate pattern response to his area players (FS & read side safety). Of the read side calls he will make (and responses) are:

CHINA

If #1 is short/hitch the corner makes a “China” call. This flags man responsibility for the Strong (read) Safety. The read side safety will run under (to) #1 because the corner is sinking (on corner route) to match the first outside short threat (flat). A short #1 with a detached #2 receiver typically is going to give you a “smash” (or China) concept, with #2 continuing to press vertical. With #1 shallow, the corner will declare “China” and immediately look to match #2 over the top (and outside). The “China” call also help identifies that there is no post threat from #1 and that #2 is the only other possible threat vertical, so the Free Safety will look to aggressively jump the route of #2.

OUT

If #1 receiver breaks out (he’s no longer vertical) the corner will continue to sink and look to match #2. The ‘out’ call alerts the Strong (read) Safety to look to rob #1 underneath at 10 yards out. Since this overhang safety is always aggressively expanding to the flat, he won’t be giving up much separation on #1, so the throw (to #1) would have to be shallow and near the sideline for a completion.

IN

If the #1 receiver is not shallow (‘china’) but breaks inside at a depth greater than 8 yards (‘dig’ / ‘curl’) , the corner will communicate an “IN” call . This alerts the read safety that there is a threat coming inside over the top (of his drop). The safety should look to become an outside-in player (he’s going to the flat right now, because he’s got a curl player dropping - the FS).

Strong (Read) Safety

The (overhang) Safety aligns 5 yards deep on #2 (removed). Versus a standard tight end or pro look, he would align 3 yards deep and 7 yards widen (discouraging being reached on perimeter action). On EMOL high-hat pass read the target depth for his drop will be 8-10 yards. He is going to remain shallow on his drop with the intent to expand to the flat as quickly because the FS will be dropping inside of him in the curl (if that is what is threatened).

Don't get hung up on semantics - the 'read' safety "swing(ing) deep to 3" is essentially the standard 'curl-to-flat' responsibility, but an emphasis on staying shallow and man-conscious. This methodology helps the defender be less dogmatic and be an aggressive matcher in coverage ( if a man runs through his zone – he's got him vertical ). The rationale behind teaching it this way is to encourage the safety to open up and get to the flat (with no landmarks).

Free Safety

The alignment of the free safety will be 8-10 yards deep over the read side guard. This allows him to gain a clear read on an uncovered linemen and an quick response path to the inside vertical threat of #2.

Once the offense breaks the huddle, the free safety will identify the backs, determine the read side and communicate to the other defensive backs, “check 2 – read right” (coverage and what side is being matched). The response of the free safety is just like robber, with the #2 receiver as his pass key:

  • #2 goes vertical, he matches all of #2 inside leverage.
  • #2 does anything but vertical, he robs the curl/post of #1.

This vertical-clue will handle all routes deeper than 8 yards. If #2 is out (and under 8 yards), the free safety is communicating “WHEEL” to the corner (see the curl-flat combo illustrated above). This is essentially telling the corner, “you have an outside route by #2 - so you have curl-post help (from FS)”. This works even if #2 isn’t going to wheel that out route, but it lets the corner know he can now back off of #1 because of the help available.

When #2 is no longer vertical (out / out-up), the free safety then reads the hips of the #1 receiver. If #1 sinks his hips (for a break) the free safety will drive at the receiver’s break and step in front of him (interception point).

If the #1 receiver doesn’t sink his hips, the free safety immediately turns into the middle of the field (away from the receiver) to rob the post.

Inside linebackers
TCU's rules split-coverage rules mean they never have to displace the 6 in the box. The stacked (inside) backers would always match 2-to-3 regardless of formation with the other (away from final 3) being the rat in the hole. So if you’re a 4-2, its all relative if you play this with a 3-3; the numbers are the same. These players doesn't have to be anywhere fast, in fact, the slower they are at reacting the better, because they should be thinking draw or screen (off pass-action) initially.

For read side linebacker, once pass shows he is to middle drop vertical to find/match the final 3 receiver. This player is looking to defend his run gap first, then take away the hot (throw). By slow-playing pass action, he always tries to make #3 go over the top of him, and from there it just becomes a "man-to-man" zone as in basketball (boxing out #3 deep).

For the away side linebacker, it is essentially the same as the read side linebacker, with the exception of matching #2 (away) vertically. Typically, this player is the (wider) bubble backer and against any 1-back look, TCU will be slanting the defensive line. This linebacker must replace the former middle-of-the-field safety in the hole. Rather than a ‘robot’ reaction away from the ‘final 3’ player, he would gain depth vertically on #2. If #2 pressed vertically after 8 yards, the away side linebacker would have to carry him man-to-man regardless if he makes a break deep in his route. It isn’t pretty, but that is the answer for 1 back routes.

Weak (Away) Safety
On pass read, this player will play like a standard curl-to-flat player in cover 3. He has no immediate curl help and will work in tandem with the corner. He does not carry #2 deeper than 8 yards and does not reroute. He should never cross the hash when responding to an inside route, as the away side linebacker will be working to that area.

This is actually a great addition to standard robber coverage and the adjustment (with split-field) principle helps prepare your players for the ‘breakable’ scenarios. In the next (soon) installment, we will go over the very basic trips (3x1) adaptation using this same coverage.

Nick Saban: Cover 3 Adaptation (Mable/Skate) To 3x1

Continuing the review of handling one-back spread formations, the next logical step after you've accounted for 2x2, is how do you handle 3x1 (trips/trey)? All your adjustments to 2x2 can be pointless if you don't have a viable solution that can be 'broken' by a 3-receiver formation.
The Saban way of handling 3x1 out of Cover 3 is known as "mable", which is code for 'man'. This is actually a standard adjustment to trips if you're basing out of quarters. "Mable" (the same thing as "skate" in Cover 6), is manning the single-receiver backside, and pushing the zone coverage to the passing numbers. You're essentially playing zone front side and man backside.



The front side players will simply match the receiving threats as they normally would out of Cover 3. A lot can be assumed that the Cover 3 adjustments to spread are philosophical changes in how the secondary is played. Actually, that isn't the case - the 'secondary' teaching is quite subtle. The fulcrum of the Rip/Liz/Mable (3 deep zone) success is going to come with your inside linebackers. Those two players will control the guts of the coverage, and fully support everything that is being handled by the secondary.

As you can see by the diagram, nothing much changes with the secondary players. We will go over how the "alert" players (M&W) are to handle 3x1 formations:


btw - this becomes the "Zeke" adjustment to any trips look


This isn't a different coverage, just a built-in system for handling stressors of the base concept, and doesn't deviate much at all (from the call side) the standard pattern-match rules.

Let's go over the rules.....


In 3x1 (mable)
Will – backer to the single split side.
  • Back flow TO – match it (jump the flare)
  • Back flow AWAY – cut the 1st crosser
Mike – backer to 3 receivers (final 3 player) Related to #3 receiver after distribution
  • #3 is inside - ROBOT, depth and jump underneath inside breaking route
  • #3 is outside - push the strong hook
Sam – (to trips) Relate to #2 receiver after distribution.
  • #3 inside (M has him) depth and jump #2
  • #3 outside carry inside-underneath
Strong Safety – (to trips)Looking to jump the first underneath receiver. Relate to #1 receiver after distribution)
  • #2 outside – jump it
  • #2 inside (S has it) buzz underneath
Corner (to trips) simply plays old 2-to-1 read Cover 3 because he has to match the 1st vertical threat.


Again, as you see the reaction of the inside linebackers becomes the fundamental under current of Rip/Liz/Mable/Skate, allowing them to aggressively play run (flow) and put them in great leverage position based on this reaction. If those inside backers are trained appropriately, you will have an automatic response to handle most every route combination.

As a footnote, I'll just say that we've covered adaptations, the evolution, of standard zone coverage (by one who has been setting successful trends for a few decades). Saban, himself, doesn't just sit in one coverage throughout a game or rely on these rules / adjustments to beat-all. His defenses and how he uses/employs them is actually quite different. Using a 'pro approach', the defense is purely situational and will handle formations, D&D, areas of the field, differently and on a situation-by-situation basis.

No-Huddle Check-With-Me Defense



With as much wide-open spread and tempo offenses out there, surely there has to be a defensive solution to match this attack.  In this post, we’ll attempt to explain and explore the concepts a defense can use to take the wind out the sails of the no-huddle spread.

In today’s game, the true 2-back tight end has become rare. The order of the day has become a standard fare of 2x2 and 3x1 with a variety of 1-back run games and basic route concepts.  Huddling has become passé, passing games more prevalent and fast-strike offenses look to jump on sleeping defenses.  Again, we can distill the conversation down the basics; with only 5 offensive linemen and 1 back, the need for an 8-man front just isn’t there (you can live in split-safety with a 7 man box). When you couple that arithmetic with no tight end, now you can control the box with just 6 defenders (necessitating a nickel look) and control the receiving threats with 5 dedicated defensive backs. 

The numbers really never change up front. You can game and align how you like, but you’re going to account for those 6 offensive gaps with your linemen and linebackers. This leads us to what you are going to do against the only other formations you will see with 1-back; 2x2 and 3x1 (and its lovechild, 3x2). We’ve dealt with this before (twins coverage variations), but we’re going to attempt to take it a step further, going beyond old-school defensive adaptations and TCU’s swimming-in-vocabulary-system, to look at the practicality of using a ‘self-correcting’ nickel. 

This is something more than just looking for a blanket 'defense' solution (“ah, well we’ll just run Cover 2!”), but using a system with built-in answers for coverage/run support that adjusts on the fly.  It requires much more player indoctrination and processing up front, but once you’ve laid the framework, it can be anything you want it to be and essentially “run by itself”.  The simplicity is tied to the communication between the safety, corner and overhang player.  They communicate every snap so there leaves little room for ‘blown coverage’ (players not understanding what each other is responsible for).  Much like match-up zone basketball, it can be reduced down to multiple 3-on-2 banjo to each side of the offensive formation.


A brief outline of the benefits of moving towards this defensive system would be:
  • 2 high all the time
  • as many coverages as you want
  • complete carry over for all defensive backs
  • consistent with quarters / 2 read basics
  • adjusts to all formations and splits without needing to alter alignment
  • adapts per game plan
  • no more zone 3 deep 3 under wait and react....jump everything aggressive like banjo
Coverage is premised on playing man (after distribution), but with a quarters feel; each side independent of the other.  The Strong Safety and Nickel travel to the passing strength / field, while the Sam and Free Safety align away / boundary.  All routes are intended to be aggressively matched with a banjo principle and as such, there is no spot-dropping.  This plays into how pressures will be run.  The traditional 3 deep / 3 under fire zones, with underneath defenders dropping to areas without aggressively jumping receiver distribution only creates more opportunities for the offense to find the voids.  Whereas in the late 90’s and early part of 2000s, defenses could just provide a +4 to a side pressure and overwhelm protection.  The area drops sufficed at that time.  In today’s game, offenses have more protection alternatives available, more streamlined concepts with built-in rush routes, and quarterbacks are becoming better suited to handle the blitz.  This is why aggressively matching (it looks like true man coverage when executed) is where more and more defenses are headed to.

By packaging your defense into fronts and coverage, there is no need to huddle. Your personnel can just line up for the next play based on the ball spot.  The front / game can be signaled from the sideline if necessary.  Coverage can be signaled but most times it is decided by each safety once the offense sets the formation.  The check-with-me is controlled by each safety, who will coordinate with his corner and nickel/backer on how to handle the receiver split they face.  Each side will act independently of the other. The secondary aligns in the same 2-high look for every snap, with corners inside #1, cocked inside facing the ball.  This position allows them to easily get a hand-gesture-signal by his safety, acknowledge it, and be ready for the play.  The no-huddle check-with-me allows the players more time to receive more information from the sideline (personnel) and anticipate what the offense will likely do in this down and distance once the formation is set.  You can establish some basic principles and work the exceptions based on game plan.
Now, let’s take a look at various ways the check-with-me coverage works against formations…... 

2x2 – So How Do You Handle Twins?
That depends – there are host of possibilities available, but the best way to look at this is how the offensive threat changes based on known variables.  This deductive method for packaging the coverage helps indoctrinate players to how they need to understand/process offenses.  As a footnote, I’ll mention that much has been explained about Rip/Liz from a 1-high coverage as a way of adjusting to spread.  However, this was created as a necessary adaptation for the time.  Despite leading the innovation for a decade, Saban rarely uses it.  In numerous seasons worth of film dating back to 2002, I was only able to locate a handful where Saban actually used true Rip/Liz against 2x2.  Why? Because he (like most defenses of today) remain 2-high every snap.
 
The illustrations here will display scheme with zones, simply to represent the banjo concept of denoting the route the defender will attack.  We will use basic terminology (it doesn't matter how you call the adjustment, just make sure there is a way to communicate the idea) as much as we can to explain each situation.  I'll say that NONE OF THIS is all that revolutionary (its been done since the 80s when teams were double calling their coverage based on pro/slot), but it does set a framework to begin building the concept of a no-huddle defense that can call its own plays.  As a preface to this discussion, please reference this post on coverages ( basic coverages ).

Field / Boundary

Facing 2 quicks to the field creates some horizontal spacing issues.  With really only 3 defenders to cover a 35 yard swath, you will need some creativity and flexibility to put numbers in your favor.  To the wide side of the field, you could drop the safety to cover this horizontal stretch, with a modified version of the old Robber coverage.  Here the safety will be force on run-action to him and jump the first threat outside.  The Nic will have help outside and maintain inside leverage on #2 and fit the alley in run support.  Since the Nic will be used in outside blitzes frequently, offenses can never really be sure what his alignment represents.  The Strong Safety will drop on 8-10 yard curl and cut outside breaks of #1 or #2.

With limited space into the boundary, the horizontal stretch of the coverage just isn't there.  You may see more leveled routes (China/Smash).  To the short side of the field, the preferred call is “Sink” or what amounts to 2 read (we called this 'monster' at my last stop).  The corner will carry a vertical of #1 and retreat to the deep flat if #2 appears (out).  The Strong Safety is in position to match #2 vertical.  The backer (Sam) will wall #2 on the receiver's stem.  On run action, safety is primary run force with corner over the top.  2 Read / Sink can be played on either side, but is particularly effective against flat/curl types of throws.

Back To / Away

Having a coverage preference based on field position is logical because you want to protect against getting leveraged.  You can also incorporate how you would like to adjust based on where the single back sets to account for likely route/run pairings.  
  • Back away: stretch/power, back flare
  • Back to: speed option
Naturally, with a back offset to the twins side, you end up with a potential threat of three receivers.  With passing strength set toward the back, in addition to running Robber explained above, you could opt to cloud (corner force) that side to include an immediate perimeter defender, expecting quick 3-man game.

With the back away from the passing strength you won't be threatened with being outnumbered immediately on the perimeter (still have a 3-on-2 advantage). An efficient way of using personnel would be to declare 'buzz', allowing the Nic to be the force defender (buzz = backer force) with the safety dropping in late to the curl/alley.  This also is a solid alternative into the boundary.
At any point, if the split is wide enough between #1 and #2 where the safety doesn't feel he can provide deep over-the-top help on #1, he has the ability to make a "swim" call that denotes that he will take #2 man-to-man.  This leaves the corner with no deep help and will be man on #1 for anything other than an immediate inside route.  This prevents being out-leveraged by #1 and #2 (works like MEG in Cover 7) but also provides a confusing change-up because the the safety exclusively matches #2 everywhere.

Another change-up that remains consistent with the relationship split-field personnel is dropping a safety into the middle of the field hole as a box player.  This is particularly effective against 2-back sets when the linebackers will be bubbled in 50 techniques (versus a single-split the corner will likely be in man coverage, anyway).  With a pro formation you'd be fine dropping both safeties outside (ala Sky) or try something else.  Here we call this "Zebra", but you can name it as you like.  The point is without a need for 3-on-2 outside based on formation, the deep safety may be better suited added to the box for run-support gap integrity. 



3x1 – You’re Only Left With One Coverage To Play Against Trips
The standard quarters answer to 3x1 was always to man the single-split and zone combo the 3-man side.  Here, we'll provide some more alternatives to this with zone matchups that will play into the field area packaging.  

Another way to play 3x1 is with “Stump” where the the corner mans #1 completely and #2 and #3 receivers are banjoed by the inside defenders (Nic, Strong Safety, and Mike).  This is particularly useful when #1 is considerably detached from the other receivers (much like "swim" outlined above). 

"Stick" is the alternative to Stump, where #3 is manned up and there remains a 3-on-2 with #1 and #2.  This is particularly effective against quick game out of trips and bubbles by #3. The Mike provides support to cut the 1st crosser of #1 or #2.

Another way to handle automatic coverage against 3x1 is with pressure.  This is best introduced from empty...

3x2 – The Rules Hold True
After already establishing how you want to play 3x1 and 2x2, these ground rules help establish a base look to stay sound against empty.  When facing a quarters defense, you can expect to see coverage rolled to the passing strength.  The standard answer against trips is to solo the backside single-receiver and end up with some type of banjo concept to the 3 receiver side.  For many defenses this is really the only solution and when faced with 3x2 empty, conventional wisdom zones everything to play it safe or go-for-broke and bring man-free pressure.

To deviate from these basic standards you would want to be able to break from conventional expectations (offenses going to trips for the purpose of getting single coverage on a receiver), but also be flexible to adjust against motion and/or passing strength changes. Previously, we discussed how the fire zone would handle trips and empty, for a more aggressive method we can flip these rules on their head.

Man Side Becomes Zone Side
The trick with no-huddle defense is always giving a static pre-snap look so an offense never really knows what it is dealing with.  Even when safeties drop, you still won’t be sure what coverage it is until the receivers are into their break.  The same holds true here for empty.

With "MASH" (Mike and Sam blitz), the 3-man side will man-free each receiver (Corner, Nic, Strong Safety).  To the 2-man side, they will banjo zone the split (often times this is going to be to the boundary) between the Corner, Mike, and Free Safety.  Corner takes first to the flat, Mike takes second out.  It all boils down to a read on #2 as to how the receiver distribution will play out (again, consistent with quarters/2 read principles).  Meanwhile, the backer away from the zone side will be a part of the 5-man pressure up front.

Empty to 3x1

This pressure also works against 3x1 or the likely shift of the the weak slot to the backfield.  If 3x2 becomes 3x1, you still have the 3-man side manned up, but if there is no immediate inside vertical threat weak, then the Mike is now included in the pressure and the Free Safety drops to replace his ‘zone’.  The Free Safety will cut the first crosser with no deep help.  Nothing really changes here, the Mike just gets replaced by the safety.

With a back in the backfield, the End away from the Free Safety will peel if the back cross releases (to the 3-man side) in an effort to help coverage.

Empty to 2x2

In the event that 3x2 becomes 2x2, likely from one of the trips side receivers shifts to the backfield, you end up with a push.  With a back in the backfield, you have a trigger to engage the Mike in the pressure (both linebackers are blitzing).  Now the only thing to figure is where the back offsets to.  The side the back sets to weighs the twins to his side as the 3-man side.  In the ‘flipped’ example below, the back sets to the former weak passing strength.  The former passing strength (to the Nic side) has shifted away, therefore the 2-man side to the Nic is now the zone-side.  The Free Safety’s side is now the passing strength with the back added to his side.  This now becomes the man-side.   The corner and Free Safety man #1 and #2 and the remaining back will be fiddled between the same-side Mike (if back releases to the Free) and the away-side DE (if back cross releases to the Nic).

An additional change up against empty is to use a Tampa 2 coverage with the Nic retreating to the deep-middle of the field. This has the exact same look as the coverages above, but becomes completely different.  Now, instead of expecting man-coverage to trips, you’d be getting a true  3-deep 4-under zone defense.  Using nickel and setting the Nic to the field, you can feign him on a blitz (will be used quite a bit in pressures, anyway) bringing him closer to the box giving him less distance to travel to get to the middle of the field.

This has been a basic overview of using a no-huddle defense against the spread with coverage alternatives.  I believe this is truly where defenses are headed in the future (many are already there now) and the need to be creative and thoroughly prepare your players to think for themselves should force us coaches to live on the bleeding edge of the game's innovations.

Good luck this season.....
