Mtn Y Corner is a trips weak passing concept out of Shotgun Y Off Trips Wk that isolates the backside receiver on a deep out and go while flooding the trips side with a corner route and two short breaking routes underneath. Motion sweeps a receiver across the formation pre snap into a comeback route to the boundary, and the Y (tight end) releases vertically before breaking to a corner route as the clear-out for the primary read. The blocking keeps the backfield clean for a full drop, making this a play action free design built to attack man coverage on the corner and comeback, with the underneath crossers serving as zone beaters and hot route options against a soft shell. Primary progression is the Y corner route first, then work back to the boundary comeback, checking down to the short in-cuts if the corner is jumped.
Watch the motion defender at the snap, if a linebacker or safety follows the motion man across the formation that confirms man coverage and opens up the comeback route immediately. Check the corner over the trips side pre snap, if he is playing off with outside leverage he is vulnerable to the Y corner route breaking to the sideline behind him. Post snap, key the underneath linebackers and any user controlled lurk defender sitting in the intermediate zone, since they can undercut the short in-cut routes if the quarterback holds the ball too long. Cover 3 with a hard flat defender can squeeze the boundary comeback, so look for the flat defender sprinting to the numbers as a sign to work the corner route instead. Press man coverage on the outside receivers combined with a single high safety is the toughest shell to beat here since it removes the clear-out advantage the Y corner route depends on.
Use the pre-snap motion to identify man versus zone before the snap, if the defender follows across the formation you have a clean man beater on the comeback. Hot route the two short in-breaking routes into deeper crossers if you see a two-high shell rolling to a single high look after motion. This play hits best on second and medium to second and long when defenses are more willing to play zone shells and give up the intermediate corner route. Pair this with Mtn Y Cross or Mtn PA Portland in your play calling sequence, since both share the same trips weak formation and motion look, forcing the defense to respect both the corner breaking route and the crossing route without tipping coverage. Against aggressive user blitzers, get the ball out on the boundary comeback quickly since the corner route takes time to develop and can be affected by pressure off the edge.
