4 passes to 3 (or 2) and screens away. 2 will curl the screen if X2 trails, X4 has to show, 4 looks to screen and slip. If X2 goes ballside, 2 will bump and fade (inside foot plant, he can cheat step), 3 drives middle trying to get a shot for 4 or 2. On a skip pass to 2, look for a post-up or duck-in by 4.
Variation - the ball starts on one wing, reverse it to the other side.
