Purpose Get the ball outside quickly when the receiver has space. This is a short screen, not a call to force against tight outside leverage.
QB key checks the defender nearest . Throw the bubble only when can catch with room to turn. If that defender drives outside and a downfield window is available, look to ; is the short outlet. The deep option still needs enough time and throwing range.
Assignments
Coach it Start with snap-and-throw reps, then add one defender who alternates between staying inside and driving the bubble. The screen receiver needs a catchable ball, not maximum velocity. No receiver blocks or screens a defender in this no-contact example.
Watch for An outside defender sitting on the bubble, a drifting snap, or a throw beyond the QB's range. Receiver width makes this throw longer than the route's depth suggests.
