The offense runs through the PF primarily. So I'd say as much PA as you can get at that position will be most beneficial. I've had PFs with 15 and 19 PA and that really unlocked abilities of the tactic even more.
You will want the best shooting at the PG and SG positions. This includes having JR, however it's not as crucial as I used to think for the position. Along with that you will want high DR and HA because your guards will still go inside for layups. Usually these looks are off the pass from your big man.
As for the C position, they will do a combination of inside and outside shots. So you will want a guy that can hit a JS, but also go inside and get a layup or dunk.
As for the PF, definitely want a great combination of outside shooting, inside shooting, and passing.
