This is a great play against a conservative secondary or a prevent defense.
Tighten receiver X's alignment and drag him across to hold the linebackers. 2 and 3 receivers are the "secondary stretchers" and aren't in the QB's read. They need to push the safety and the corner deep and as fast as possible.
Throw to receiver 1 as he runs a deep post 20 to 22 yards. Because of the alignment, 1 will be behind receivers 2 and 3. The inside and outside LBs will never drop that deep. If they do, hit receiver X as he's dragging across the field.
