This is a good play to use anywhere between your own 10 yard line and your opponent’s 15. We shift receiver Y over and spread receiver’s X and Z while 3 shuffles. The offensive line blocks man with the center going right (rip).
On the snap, the QB executes a 5-step drop and checks off toward X to throw off the DBs. The QB then reads his receivers in a progression of Z, Y and 3, with 3 being the hot receiver.
