1 Leads to the ball, and is then back screened by 2. 4&5 remain in a double low screen at this stage.
1 goes hard at the basket off the back screen with a possible lob pass and score.
If 1does not receive the pass, he would flair wide to receive the ball reversal.
2 steps high and receives the pass from 3
2 reverses the ball to 1
With ball reversal 3 cuts hard off the double low screen.
If open he would catch and score.
If 5 defense sags to cover 3 then 5 would step to the free throw area for the easy shot.
4 turns and faces after the screen for 5.
2 remains high as a safety.
5 would catch and shoot or have two receivers at the low post area.
In this case the ball goes to 3.
