2 cuts through as 5 moves up to screen x1. 5 lets x1 over the top to set up the next part of the play.
 

5 re-screens x1. As soon as 1 clears the screen he passes to 2. 5 then rolls down the lane for a post up chance.
 

2 has an open shot or the extra-pass look to 3 in the corner, depending on x3. 5 is open cutting down the lane.

Add-on:

4 set a flare screen on x2. If x4 releases to help, dive for the lob pass because x5 should be picking up 5 on the roll.
