5 runs deep. 1st Option is 2 curls tight around 4 and to the opposite block. 3 looks to hit 2 at any point if he is open and running on the baseline if need be to get a better entry angle.
 

2nd Option is as soon as 2 clears 4 then 4 takes two steps to diagonal screen for PG to the ball. 3 looks to enter to PG.
 

3rd Option is 4 either rolling back to the ball or....
 

...4 getting the defense on his low side and simply throwing over the top and letting 4 go get it.
