1 passes to 4.
1 sprints and screens for 2.
2 cuts up the three point line.
5 sets a ball screen for 4.
4 uses the ball screen and is looking to either get their own shot or hit 5 on a roll to the basket.
If 5 is not open, 4 will pass back to 2.
2's first option is to get their shot. If not they look for 5 sealing their defender in the post.
