Y Stick out of Trips Left Open in Pistol sends the three receiver trips side into a classic stick concept: the outside receiver runs a short in breaking towards the sideline, the slot runs a vertical seam/go up the numbers, and the inner slot (Y) settles into a quick stick route sitting down in the underneath zone. The backside single receiver runs a skinny post working against single coverage. This is a timing based man and zone beater built on stick concept spacing, with the running back staying in to help protect and no play-action deception, making it a quick game pass designed to get the ball out fast against blitzes or off coverage.
Watch for Cover 3 or Cover 4 shells with off man corners, since the stick route will find soft grass in the flat against zone drops. If the defense shows a nickel blitz with the slot corner crashing downhill, get the ball out immediately on the stick route before the pocket collapses. Key the middle linebacker's depth at the snap, if he sinks deep into a zone drop the seam route up the numbers on the vertical will be open behind him. Man coverage with a linebacker matched on the stick route is the easiest matchup to exploit since the running back or tight end can win with the quick settle. Watch for a lurking safety rotating late over the trips side, this indicates a disguised zone blitz or Cover 2 look that can jump the stick route if the quarterback holds the ball too long.
Pre-snap, identify if the defense is showing man or zone by checking cornerback depth on the trips side, tight press alignment usually signals man coverage which favors the stick route sitting in the void.
Use this play on third and short or second and short since the stick route and quick in route are designed to get easy yards after the catch against soft cushions.
If you see a single high safety with the corner playing outside leverage on the backside post, hot route the post receiver to a slant to beat a quick jam.
Combine Y Stick with Four Verticals from the same set to keep the defense honest, since both plays start with similar trips alignment but attack differently if the defense starts sitting on the short stick route.
Against zone heavy defenses, key on the stick route first since it sits in the flat zone soft spot, then progress to the seam route if a linebacker widens out to cover it.
