No problem – the concept of what the defense is attempting to do is simple (stuff the run and deal with the receivers as they present themselves), so there is no reason to wet the bed. Versus trades or Y motion, they will simply flip the SLB and Strong Safety, to maintain the matchup with the SLB on the 3-man surface.
This keeps a 3-on-2 advantage for the defense with the Strong Safety joining the MLB and WLB in the box. The same pattern-matching rules apply.
Y FLEX
Okay, so that doesn’t cause the defense any problems, eh? How about if the offense flexes the Y from the formation (a legitimate conundrum for most defenses)? Do you treat this guy as a receiver, do you treat him as a run-blocking tight end on the perimeter, how do you matchup?
If the Y removes himself from the formation, there no longer becomes a reason to play a 9 technique SLB. The Strong Safety will make a “Switch” call, so the backers will re-rack into the traditional 50-10-40 alignment within the box (again, gaining the 3-on-2 advantage, this time with the SLB, WLB, and MLB) and he will take the SLB’s former assignment and the SLB will take the Strong Safety’s former assignment. With the TE displaced from the box, the adjuster of the defense (strong safety) will walk out to match his alignment (just like he would do as a sky support player in Cover 3). The Strong Safety will man up with the Y, leaving the SLB to match up with #2 strong / WLB with #2 weak (or rat) / MLB #3 strong (or rat).
Brophy Can you explain the difference and how you detemine the (pass) strength of a formation vs. the (run strength) of a formation?
ReplyDeleteI read you lsu defense playbook on your site where it explains the pass strength (2wr side and Te any combo of the 3) But the running strength I don't understand.
Thanks Good article
Typically a run-strength will be determined by the TE. The passing-strength is based on the passing-numbers. It is rather academic and shouldn't be as convoluted as it sounds (it isn't). More often than not, they are one in the same. However, if you end up with a twins look away from the TE, most people would set their front (strong side personnel) to the TE side, and any coverage adjustment would be handled by recognizing the passing strength to the most receiving threats (twins). Like I mentioned, the only time the two wouldn't be the same is with minor exceptions. This aides in setting your personnel (SS or FS) to the appropriate matchup.
ReplyDeleteSome defenses, this doesn't even matter, especially when there isn't any discrepancy in player-types/personnel
