It was meant to be a FastDraw joke. With the right timing, it may actually work.
Diagram 1: 1 passes to 5 to initiate movement. 4 screens for 1. 5 dribbles towards 2 for a hand-off as 3 moves to the strong side of the floor.
Diagram 2: 2 immediately passes to 3 as 5 posts. 1 then backscreens for 4 (3 looks for the lob). If x1 and x4 move towards 4, 3 looks to pass to 1 for the 3PA.
I’d love to know if any one actually executes this in a game.
