Gaggle Screen - as 1 comes off 5's screen, 3 fakes the second screen of a staggered double and cuts right off of 5's outside hip. 4 spaces to corner after the screen. 2 hits 3 for the layup.
 

If 3 is not open, 2 reverses to 1 and cuts to top of key. 4 circles to wing and 3 spaces to corner. 5 is trying to seal defender in post.
