PA Boot Y Sail (m20)

Pre-snap, check safety depth and corner alignment, if you see two deep safeties with off corners that is Cover 2 and the flat defender becomes your primary conflict player to attack with the sail route. Against Cover 3, identify the flat defender rolling down to the boot side, if he widens with the flat route the sail sitting at 20 yards behind him is wide open in the seam of the coverage. Watch for a user controlled linebacker or safety sitting in the throwing lane as a lurk threat, since aggressive human defenders will often jump the sail route if they read play action quickly, so have your backside dig or crosser ready as an outlet. Man coverage with an overhang blitzer or nano blitz on the boot side is the biggest threat to this play, since the quarterback rollout eliminates his ability to escape pressure away from the blitz, so recognize man alignment (tight press corners, no deep safety help) and consider checking to a quicker breaking concept instead. Post-snap, track the underneath linebackers, if they bite hard on the run fake and vacate the middle of the field, the backside crosser becomes a home run outlet against a Cover 3 defense that has lost its middle field integrity.
