PA Flood runs a play-action fake to the backfield out of Singleback Wing Tight, then floods one side of the field with three levels of routes stacked on top of each other. The wing TE runs a deep corner route from the boundary, the outside receiver on that side runs a flat route underneath, and the backside receiver crosses the field on a deep dig against the grain to hold the deep safety and give the QB an outlet if the flood side is jumped. Blocking is play-action protection with the offensive line selling run to freeze linebackers, making this a classic Cover 3 beater built around a vertical flood progression: read the deep corner first, work down to the flat route, and come back to the backside dig if the strong safety squats on the flood.
Key the flow of the strong safety and outside cornerback on the flood side immediately after the snap to identify if you are facing zone or man coverage. Cover 3 with a single deep safety over the top is the primary shell this beats, since the flood overloads the deep third defender with three routes to one side. Man coverage with a deep half safety can shut this down if the defense disguises Cover 4 or Cover 2 post snap, since the corner route runs into two defenders instead of one. Watch for a user-controlled defender sitting in a lurk or spy position near the flat, since a smart user can jump the shallow route and bait the QB into a pick. Blitz packages that bring extra rushers off the edge can disrupt the play-action fake timing, so identify overload blitzes pre-snap and be ready to get the ball out quickly on the flat route as a checkdown.
Call this on early downs or second and medium when defenses are still respecting the run fake off Singleback Wing Tight tendencies.
Check the pre-snap safety alignment: if you see two high safeties rotating to a Cover 3 shell after the snap, the flood side will be a numbers advantage.
Use play-action rollouts with pump fakes if the pass rush closes fast, since the flood concept gives you a rhythm timing throw to the flat if the deep corner is capped.
Hot route the backside dig runner into a deeper drag if you are facing zone with a fast flowing linebacker, since it opens a natural throwback window.
Pair this with HB Inside Zone or 26 Duo out of the same set to sell the run fake harder, then sequence into PA Y Sail or PA Boot Flood later in the drive once the defense starts jumping the flood route.
