PA Fork out of Singleback Wing Slot 12 personnel uses play-action to hold the linebackers before working a vertical stretch on one side of the field. The backside receiver runs a deep crossing route from the numbers all the way across the field, while the two receivers on the play side split into a fork concept: one bends outside on a corner-breaking route toward the sideline and the other climbs vertically up the seam. The flat route underneath clears out to the opposite side, and the single receiver at the top runs a deep vertical to hold the corner. This is a play-action shot play designed to beat man coverage by creating natural high-low and inside-outside conflicts for a single defender, with the primary read starting on the seam vertical route before working to the crossing route underneath if the safety rotates over the top.
Pre-snap, check for two deep safeties versus a single high safety since PA Fork is designed to attack the void created when a safety has to choose between the seam and the corner route. Watch linebacker depth at the snap. Linebackers who step up hard on the play fake open a throwing lane on the crossing route working across the middle of the field. If the defense shows man coverage across the board with no deep safety help, the seam vertical route wins against most linebackers and slower nickel corners. Zone coverage with a deep half safety rolling to the play side can shut down the corner route, so the quarterback should reset to the crossing route as a zone beater. Watch for a user-controlled defender sitting in a lurk spot near the seam, since that is the exact throwing window this concept targets and a smart user can jump the route if the quarterback holds it too long. A blitz that brings extra rushers off the edge can collapse the pocket before the play fake finishes, so identify overload blitz looks pre-snap and consider a hot route or quick check to the flat.
Sell the play fake by holding the snap button or letting the animation finish so linebackers commit downhill before you attack the seam.
Use this on early downs (first or second and short to medium) when the defense expects run out of 12 personnel with two tight ends on the field.
Check the safety alignment pre-snap. If you see two high safeties rotate to a single high shell after the snap, that is your cue to hit the deep crossing route instead of forcing the seam throw.
Pair this with PA FL Dive or PA Power O earlier in a drive to get defenders keying run action, then dial up PA Fork to punish linebackers who bite on the fake.
If the defense shows man coverage with no safety help over the top, trust the seam route matchup against a linebacker or nickel defender.
Motion the slot receiver pre-snap to identify man versus zone before committing to your first read.
