PA Snag out of Shotgun Normal Y Off Close uses play-action to hold the linebackers before attacking the boundary with a three-level Snag concept. The outside receiver runs a corner route stretching the deep third, the inner receiver sits down on a shallow snag/hitch just past the sticks, and a third route works underneath as the flat component off the play fake. The single receiver backside runs a go route to hold the safety, while the offensive line executes a play-action pass block to sell run fake before protecting. This is a Cover 3 beater by design: the corner route occupies the deep third defender, the flat route pulls the underneath flat defender, and the snag sits in the window between them, giving the quarterback a high-low read starting with the snag route and progressing to the corner if the flat defender squats.
Key the flat defender immediately after the play-action fake, if he sinks under the snag route the corner route behind him is open for a big gain. Watch for a user-controlled linebacker or safety sitting in the underneath passing lane, that lurk threat can jump the snag route if the quarterback stares it down too long. Man coverage with press corners is vulnerable to this concept since the corner route can win over the top, but a physical jam at the line can disrupt the timing of the play-action fake. Cover 4 or quarters shells with safeties reading run keys quickly can rob the corner route, so check if the safety stays high and undisturbed by the play fake before committing to that throw. Blitz packages that bring extra defenders off the edge opposite the single receiver exploit the play-action protection, so identify overload blitz looks pre-snap and be ready to hot route the backside route into a quick outlet.
Use this play on early downs when you have already established the run, since the play-action fake needs linebackers biting downhill to open up the snag window.
Check the safety alignment pre-snap: two deep safeties shading toward the trips or close side signals Cover 2 or Cover 4, which means you should prioritize the corner route over the snag since the flat defender will likely carry the underneath route.
Against Cover 3 shells with a single high safety, work the snag route first since the flat defender has to choose between the flat and the snag sitting down in the same area.
Hot route the backside go route into a quick slant or drag if you are facing pressure looks, since the single receiver side has no help against a blitz off that edge.
Pair this play with Mtn Snag Curls or RPO Zone Snag from the same set to keep the defense guessing between the play-action shot and the quicker RPO reads, forcing linebackers to hesitate on run fits.
