1 passes to 2 and sets a screen for 3, this will help 3 get free at the top of the bucket.
As soon as 2 receives the ball he must decide to go for the one to one or pass to 3 at the top of the buchet.
Important: 4 takes a quick look for the ball from 2, but will almost never receive the ball. After that 4 goes to block 5 on the opposite side.
