I think Inside ISO plays a lot like Orlando did last year with Dwight - so Inside-Out tactic. He is surrounded with shooters who try to play a P&R with him or they just pass him the ball and if he doesn't come into position to score, he passes out to somone who is open because normally Dwight is being double-teamed a lot.
Not sure if this is a definition of Princeton, but it seems like Inside ISO and Princeton have a lot in common.
