Posts and guard work in tandems to get open in the short corner areas

3 curls off of 4, while 2 bumps to the corner off of 5.

PG looks to either side
 

4 pops to wing area

3 posts up on block

5 floats to block

2 spaces in the corner

1 passes to 4
 

4 takes a dribble (if necesary) inside the 3pt line

3 fakes a cross screen to 5, then sprints/curls behind 4

4 flips it to 3 for a 3pt shot

If posts helps, play two-man game on the mismatch.
