Slot Coverage Variations

After covering front matching previously, we can now explore options available to handle slot sets that are separated from the box. Typically, this is best understood from a 2-back look with a single receiver on the other side of the slot (allowing a variety of bracket looks and the linebackers matching back flow). The passing strength is immediately identified (slot) and the safety, corner, and overhang player can communicate how they would handle the 2-man routes out of this. These methods can also be applied independently to each side (split-field) when facing 1-back, as well.
 
With two receivers split from the formation (slot) you end up with a 3-on-2 advantage for the defense. As we covered before, there is a variety of ways to handle this. In attempt to tackle two things at once, we’ll cover these concepts using Saban-speak (out of Nick Saban’s playbooks). It should be noted that Saban’s “system” is extremely concise, flexible, and modular (in its application). What comes with those benefits is a dictionary full of terminology to communicate every conceivable action and response on the field. We’ll use his method as a way to keep a central thematic framework, but these concepts are relative to what everyone else does (so don’t get hung up on the verbiage).
FIST

The first is basic Cover 3 Sky (“Fist”) with what amounts to be the old “country cover 3”. Fist brings the overhang player down outside of #2 receiver serving as primary force. This defender will drop into the seam and not carry any route by #2 deeper than 12 yards and jump the first receiver to the flat. The corner would play all of #1 receiver vertical (or #2) out and up. The free safety would play middle of the field to the #2 receiver. Because these two receivers are handled by these three players, additional receivers (releasing back) would be immediately jumped by the next linebacker inside (Will) unless #1 or #2 released inside.
 
Examples of matching in Fist

     

Exceptions

• Vs 1 back – the FS will check to Rip/Liz rules (match left/right away side) and man #1 and #2.
  
• Vs Wide slot split (horizontal stretch) – with a great deal of space underneath to cover, a “TOKYO” (smash rule) call can be made to have the corner take all short routes and have the overhang defender carry a vertical stem.

 
Sky (Fist) remains an all-purpose coverage solution to slot, but can face limitations with quick 2-man games against the overhang player.



 
COVER R - ROBBER

We’ve covered robber coverage before and this version would be just like Virginia Tech plays it. This is best against a tight #2 with the FS dropping into the seam and the overhang player immediately expanding to the curl. This isn’t much different than TCU’s ‘2 Read’ (covered before). The FS acts as the robber, reading #2-to-#1, playing the front hook with a #2-to-QB-to-Alley fit progression.
 
The corner immediately drops to the deep third with the overhang defender jumping first receiver to the flat. With the corner committing to the deep half, any vertical route by #2 will be bracketed inside-out by the FS and corner.

Robber coverage remains arguably one of the best run down solutions, especially to the field.  1-back looks can be handled by robber, but do not provide the leverage security that 2-back does.
 
 

COVER 2 - CORA

This is traditional cover 2 cloud with the FS over the top in deep half coverage and defenders in the curl and flat. The overhang player will align inside #2 and the corner outside of #1.  With two outside underneath zone defenders on top of two split receivers, you have the ability to aggressively attack the quick game.  With any slot coverage, you are only as good as your answer to the smash route.  With true ‘Cora’, the force corner will sink in the flat (playing “TOKYO”) and the overhang will carry #2 vertical.

 
examples of matching in Cover 2  

 
Cover 2 is great against quick game and perimeter run game.  How a defense matches vertical routes in Cover 2 will typically be its weak spot.
 
 
One adjustment to this Cover 2 look is known as “Leach”. It is exactly the same with the exception of the overhang defender is man-to-man #2 (slot/curl). This would afford the (usually exceptional) slot receiver to be double-covered underneath or deep with the surrounding zone defenders.
 

COVER 4 - THUMBS

Thumbs is a 3-on-2 quarters principle that can morph itself into swipe bracket when only one receiver is vertical. The FS will double #1 or #2 from inside out with the corner playing deep third outside.  The overhang player is the sole underneath defender and will take first shallow out / in receiver between #1 & #2.

Quarters is great against vertical game and play-action, but the lack of underneath support can cause perimeter leverage issues the offense can exploit.
   

COVER 5 – COUGAR / IOWA
Adding this as a final thought, Cover 5 is the man-under with deep half help. The FS will rob everything inside with the ability to double either receiver deep.  I didn’t provide any illustrations as it is pretty self-explanatory and is the ideal passing coverage.  The FS will rob everything from the inside.  Because the corner (your best cover guy) will be man-to-man on #1 outside wide “on an island”, you will typically have a 2-on-1 cone/bracket on #2 between the deep safety and the overhang player.

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 3^rd player that he has a route approaching (“cut” as the hole defender). The final 3^rd 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 3^rd player just replace one another’s receiver, though the distribution remains consistent (the shallow becomes the 3^rd route, the flare is the 2^nd route, and the post is the 1^st 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 3^rd 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 3^rd 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 3^rd player know he has a receiver crossing the formation (becoming the 3^rd receiver / 1^st 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 3^rd 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.

The slot coverage post is coming.  This pattern match post just happened to be ready first and I don’t want to sit on anything that could help.

Also, if you haven’t figured it out already, our former YouTube account that included many of the cut-ups featured in previous posts has been deleted by Google/NFL Properties.  Hope you downloaded / picked up on those video illustrations while they were up.

Coverage: It’s Academic

Believe it or not, we’re entering the fifth season of this blog, though only getting the hang of it for the last three.  That being said, the next few posts will lean heavily on archived content so not to insult any of you readers by retreading previous topics.

As we’ve covered before,  remaining gap-sound in run-support is a fundamental equation that is addressed every snap based on the formation.  In this post, we’ll look to set a foundation of defensive concepts through fragmentation.  After setting this ground work, it will be followed with different alternative coverage adaptations available to a defense.

One of the biggest mistakes for those learning the game of football is to fixate on the minutiae of various “brands” of defense.  Tying oneself to the dogmatic thinking and going-through-the-motions of “how we’ve always done it” without understanding the rationale of how it all works creates an intelligence rut that becomes a liability.  Defenses exist to defense an offense – they do not exist within vacuums.  On every play you’re defending something the offense is doing to advance the ball.  For this reason, defenses aren’t static entities – they must respond (adapt) to the stimuli they are presented with.   You will hear people declare, “we are a 3-4 Quarters defense” or something to that effect.  That’s great, but there is a reason a defensive concept is employed on a given down, and there is no catch-all defense available.

"Exhibit A"
Belichick on Defense

“At the Browns we played a 4-3,” Belichick said. “We won two Super Bowls playing a 4-3. In ’01 and (‘04). Second half of the ’01 season, we played 4-3 after Bryan Cox and (Ted) Johnson got hurt.”
“In all honesty, most people thought we played a 4-3 at the Giants,” Belichick said.

“Lawrence Taylor did a lot more rushing than he did pass dropping. He was probably 90 percent of the time, 80 to 90 percent of the time he was the rusher in the defense. Now not every play was a pass, but certainly in passing situations and on a lot of pass plays, he was the designated fourth rusher which really put us in what amounts to a 4-3. I think honestly that’s somethingthat’s a media fabrication. There are a lot of different alignments out there, you see 4-3 teams use odd spacing, you see 3-4 teams use even spacing.”

“Look, you have 11 players,” Belichick continued. “You can put them in various positions. Whether you want to put it in the pregame depth chart as one thing or another I think is a little bit overrated. You play different fronts, you play different spacings and you teach the techniques of your defense and that is what is consistent. The techniques that are taught in the different defensive systems, whichever one you want to talk about, are consistent within those systems.

A defense really just needs to be concerned about offensive numbers (and how to match them) and the offensive capabilities from their alignment.

While touched on a while ago with TCU’s split-field philosophy,  the divorcing of the secondary from the front minimizes the detail of checks a defense would need to concern itself with as well as compartmentalizing the teaching method for each player position.  While coverage and front remain related by arithmetic, they can become independent of one another and still function together seamlessly.

its nothing but numbers

First things first is to match the front.  In every offensive formation you will have 5 offensive linemen, creating 6 gaps for an offense to attack.  The defense should have a plan to account for these 6 gaps presented, typically with 6 defenders (i.e. “the box”).  If we (continue to) use the 42 Nickel as a base concept (all of this remains true if you’re a 4-3, 3-4, 33, 50, etc), your bare minimum in the box will be 6 defenders that won’t ever have a reason to “break” their alignment because they ARE the box (they are the minimum gaps being defensed).

As more offensive players are introduced into the box, they create additional areas of attack through leverage (gaps).  The defense will fundamentally respond by adding more defenders to this area or risk being out-numbered at the point of attack.



Adding an additional back or tight end to the formation creates even more running lanes, necessitating yet another defender into the box to compensate.


All of this becomes a very academic application that generally gives you a clue as to what and how an offense is trying to set up its next play;

• if you get 1-back you’ll have 7 gaps
  
• if you get 2-back you’ll have 8 gaps

It also lays a conceptual ‘budget’ for the coordinator.  If you get X personnel grouping, you need to respond with Y defensive package and anticipate a limited selection of attacks.

After addressing the numbers in the box, you will have to figure out what you’re going to do with those other guys left in the secondary.   For the remainder of this post (and subsequent posts), we will ignore the box defenders and fragment our discussion into the leftovers of the formation.
With 1-back, we’ll have 2x2 (4 immediate vertical threats) and 5 defenders to match them.
With 2-back, we’ll have 3 immediate vertical threats with (essentially) 4 defenders to compensate.  With 2-back (or 3x1), you can get away with doing some flexible things to the single-split side without carrying tremendous risk.

 

Like we discussed in the earlier TCU 2-Read post, we’re going to narrow our focus on the 3-on-2 matchup to the slot receiver side.  When the defense is presented with two split receivers it faces an immediate horizontal stretch (away from the box) while being threatened with a vertical / levels attack.

Fortunately, because of the numbers advantage, there are several ways to play this set between these three defenders (with each having distinct advantages).  Keep in mind, the variations listed below could plug-and-play any one of these defenders into a role (hence the multiplicity in how slot is treated).

You could feature 1 underneath force player and 2 deep coverage defenders (sky, cloud,  buzz).  This could be country Cover 3, quarter-halves, or bracket coverage on the #1 receiver.
You could have 1 deep defender over the top of 2 underneath defenders.  This could be anything such as traditional Cover 2, robber or bracket coverage on #2.
Or have 1 deep defender with 1 underneath (seam) defender that could be Quarters (Meg) or fire zone.

Or it could simply be man-under coverage with deep help.
All of these alternatives can be played from one defensive (presnap) alignment, yet create a world of hurt if an offense filtered their throws through defender reads.

A feature of this exposition should be to illustrate how "what TCU does" (in the secondary) is actually what every other defense (NCAA/NFL) does - they both end up in the same scheme when its all said and done.  With TCU's patented "3 coverages", you end up with a combination of 9 coverages available (2, Blue, 5, 25, 2 Blue, Blue 5, Blue 2, 5 Blue, 52).  All of this is a result of how the slot is played.  Whether you are the Horned Frogs, the New York Giants, or the San Diego State Aztecs.....whatever scheme you call yourself playing; you arrive at the same destination.

With this preface set, in the next few posts we will discuss the many different slot coverage adaptations available to a defensive coordinator.  We’ll explore how they work within the overall scheme, why it is advantageous to not only treat slot sets differently, but also how to effectively keep quarterbacks guessing when confronted with all the variations the defense can give them.

Noel Mazzone 1-Back Offensive System

why the hell not?

Using the Tony Franklin model of marketing and production, it looks like the charismatic, innovative, and altogether-likeable coach’s coach, Noel Mazzone, has his trademarked football system available through Championship Systems.  Though I know little about this new product, I'm sure this will be a great resource for coaches, the same as “The System” has been for so many others.

If you've seen any of Mazzone's presentations this year or caught any of his webinars with Glazier, you'll know he's pretty liberal with the game and (recent) practice footage and explaining in detail each concept he uses and how he applies it in a game.

We currently have all the drill and play clips from Coach Noel Mazzone’s ASU spring practices and hundreds more offense clips for client coaches to study.  He has already completed his spring install schedule with ppts and play rules, his HS playbook, and video cuts of QB drills.  We also have his 48 page QB manual and 40 page QB techniques/fundamentals book for the development of young QBs for coaches to print and have.  

We have just put up his OL techniques, vertical set, and pass protections webinars and his whiteboard series filmed at ASU has been a huge hit with clients!  He begins his summer webinar series this Thursday for all his members only coaches and will be covering his entire offense from A-Z with drills, video, play cut-ups, and coaching strategies.  His HS playbook, install packets, and QB drills/video are excellent!  Plus, he just finished a one on one session with one of our client college staffs in Minneapolis and a team camp for a high school in Idaho!!  Everywhere he goes, he gets rave reviews on what he is doing with his system!

Visit their website ( http://nzonesystem.com/ ) or give them a call at 719-964-2111 for more information.

* if we’re lucky, hemlock will return soon with a deep look at Mazzone’s philosophy over the years, trending the prevailing memes of the game from the past two decades.
