2 makes a L-cut at foul line to receive a pass from 1.

1 makes a basket cut (if open, pass), and clears out to replace 4 (4 fills in for 2).

As 1 cuts to basket, 3 makes L-cut at foul line, to receive pass from 2.
2 makes basket cut (if open, pass), and clears out to replace 5 (5 fills in for 3).

This is effective as the defense begins to predict the pass at the top.
