Y Stick out of Shotgun Trey Open Offset lines up with a bunched trips look to the left and a single receiver to the right. The trips side runs the classic stick concept: the outside receiver clears deep on a corner-ish out breaker, the middle stick runs a quick hitch/settle route, and the inside receiver runs a shallow drag underneath to the flat, creating a horizontal stretch on any underneath defender. The backside single receiver runs a vertical seam to hold the deep safety while the RB or blocker shown with the red arrow steps up to check release protection. This is a man and zone beater built for a fast triangle read: work stick to flat to corner based on the flow of the underneath defenders.
Key the flat defender or curl to flat zone defender first, if he widens with the drag the stick sits open in the void behind him. Watch for a nano blitz or extra rusher off the edge, since the trips bunch alignment can create natural blocking confusion if the offense does not identify the extra man presniff. Against man coverage look for a linebacker or safety trying to cover the drag route out of the bunch, that mismatch is an easy throw. Single high safety shells are vulnerable to the backside seam, but if the safety rotates over presnap to double the seam receiver the trips side becomes the primary read. Cover 3 with a hard sinking corner can take away the outside corner route, so be ready to work the stick and drag underneath instead of forcing the ball deep.
Presnap identify if the defense is showing 2 high or single high safety, since the backside seam will hold a single high safety and open throwing lanes to the trips side.
Read the stick route first, if the flat defender sits on the drag route throw the stick immediately for a quick, safe completion.
Against man coverage hot route the drag to a corner route or use motion to create natural rub leverage and separation off the bunch look.
This play excels on third and short to third and medium because the stick and drag combo gives you two immediate underneath options against zone drops.
Pair Y Stick with Four Verticals or PA Read from the same formation to keep linebackers honest and prevent them from sitting on the quick stick route after seeing it on tape.
