He doesn't fit well in the triangle yet because the SF position is pretty hard--he needs to be moving and cutting all the time.
Give him one more year, and he will play like Rick Fox.
Also partially because of Ron, the edge the Celts had in "physicality" is gone. They can bully the Lakers no more with Crazy Ron Ron as the enforcer.
He held PP in check darn well too.
Of course he shouldn't have shot that many. But the biggest problem I have with him is his dribble. He disrupted the flow quite a bit yesterday.
