Not in any team playbook.
PA Post Y-Corner runs out of Shotgun Bunch Y-Flex with a play-action fake to hold the linebackers before the QB works the pass. Off the bunch alignment, one receiver breaks outside and up the sideline on a deep corner route while the middle receiver runs a post that crosses the field, and a third releases underneath on a shallow drag away from the formation. This is a man beater built to attack off play-action, with the corner and post creating a natural high-low stretch on any defender in coverage over the top, and the primary read progression starts with the corner route for the vertical shot before working back to the post and settling on the underneath drag if the defense sits deep.
Key the safety depth before the snap, since a two high shell forces the QB to hold the corner route longer and gives defenders time to sink under it. Watch for the linebacker responsible for the play-action fake, if he bites hard on the run look the post route will be wide open behind him in the intermediate zone. User the deep half defender on the corner route side in Cover 4 or Cover 2 looks, since that route is designed to climb the sideline right into a vacated void if the user does not stay disciplined. In man coverage schemes, jump the underneath drag route early since it is the easiest completion and quarterbacks will check it down if the top routes are covered. Bring pressure off the edge opposite the bunch to disrupt the play-action timing, since a clean pocket lets the corner route develop fully and the drag becomes a low value checkdown instead of a scramble outlet.
Use pre-snap motion or a shift to identify if the defense is rotating to the bunch, since a hard roll to the trips side signals man coverage or a blitz look. Look for single high safety shells before the snap, since the post route behind a Cover 3 or Cover 1 shell will split the safety and the corner route for an explosive gain. Hot route the shallow drag into a deeper option against zone heavy defenses if you need more spacing underneath the corner and post combo. Pair this play with HB Choice or Inside Zone earlier in a drive so the play-action fake actually freezes linebackers instead of getting sniffed out immediately. Best called on second or third and medium when defenses start expecting quick game or RPO Zone Alert Omaha out of the same set, since the double move up top punishes aggressive zone drops.
