Option 1:

1 enters the ball to 5 and immediately cuts through to screen opposite corner on the flex screen.

4 sets a pindown for 1 to use after screening in the flex action.

5 can hit 2 coming across or 1 off the pindown.

Option 2: Counter

Initial action is the exact same with the entry and the cut by 1 to screen. Instead of 2 taking the screen and going across the lane, 1 changes the angle of the screen slightly and 4 sets the second in the double staggered for 2 to receive the ball.
