PA Corner out of Shotgun Tight Y Off Wk uses play-action to hold the linebackers before releasing three vertical threats into the secondary. The backside receiver runs a deep corner route while the frontside TE and outside receiver both climb into deep comeback breaking routes toward the sideline, stacking the field with three high-low stems against the corner side and a fourth receiver running a skinny post/flag up the numbers. This is a play-action shot play designed to attack single-high and zone shells, with the primary read starting at the corner route on the backside before working to the intermediate comeback breaking routes if the safety jumps the corner.
Identify single-high safety alignment pre-snap, this play thrives when the deep half is not split because the corner route has room to work outside the numbers. Watch the flat defender and corner post-snap, if he sinks with the corner route the comeback breaking routes underneath will be open in the void. Beware of Cover 3 zone drops with a hard-charging user linebacker on the play-action fake, delayed blitzes can disrupt the timing of the deep routes. Man coverage with a single-high safety is the best matchup since the corner route creates natural separation against trail technique. If the defense shows two-high shell pre-snap, expect the deep half to be covered and adjust to the shorter comeback routes rather than forcing the corner throw.
Run this off early down tendencies once you have established the run game so linebackers bite on the play-action fake.
Check pre-snap for single-high safety looks, this play is built to isolate the deep corner route against a corner who has to respect the flat and the fade at the same time.
If the defense shows two-high shell, hot route the underneath comeback routes to sit down against zone rather than pushing vertical into a covered deep half.
Pair this with Y Lead Read Option or Inside Zone from the same set to keep linebackers honest before dialing up the play-action shot.
Use in second and medium or first and ten situations where defenses are more likely to play base coverage and bite on the run fake.
