Adjusting FZ Coverage vs. RPO

LSU is in a bunch formation from 20 personnel with a FB body aligned on the hip running a conflict RPO. The concept blends a counter run scheme with a glance route to the X receiver. The read is the weak safety.

QB meshes with the RB reading the weak safety. If the safety rotates/triggers into the run fit the ball is going to the glance behind his head.

If the Safety stays deep the ball is handed to the RB and the defense does not have a +1 to the weak side. The usage of a bunch formation also helps the offensive concept here. The bunch formation strong deters the defense from bumping the LB's weak. Any bump by the backers weak creates stress for  the defense against the possibility of bunch side runs and 4 strong route concepts. 

This is a really nice play design from LSU. The Georgia Southern defense is in a weak fire zone  pressure and has a numbers advantage in the run game if the ball was handed off on the counter. Part of fire zone pressure's success has been the ability to attack run schemes by winning numbers at the point of attack. RPO's are in part a reaction to defensive schemes like fire zone pressure that are problematic. Can't run into the defensive look, just throw the attached pass concept.  Tough to block the +1 defender, just read him. 

This offseason we will be working in spring ball on some fire zone adjustments we have had in the playbook but have not featured. Specifically getting the corners involved as the Seam player.

Same pressure concept with a job swap. The corner is replacing the safety as the seam flat player while the safety is taking over the 1/3 responsibility for the corner. We have used the corner in a trap technique in 4 under 2 deep and sim pressure concepts but not in 3 under 3 deep. This adjustment gives the QB a give read while allowing the defense to remain +1 to the pressure side. 

With offenses continuing to advance with RPO concepts, we are going to have to keep adjusting/adding concepts on defense.

Why do you need all those coverage concepts?

If we keep it simple on defense the reads for the offense are simple and they probably have a really good RPO concept that is going to be a problem. Fundamentals, effort, and physical play will always be our foundation but they don't solve every problem. We have to have scheme answers.
