dnbman, TheBeagle: Just wanna mention that Diaw is quite the opposite of arrogant. He is very talented but really the main problem with his play in Phoenix was that he defered too much to other players, he was especially tentative when playing alongside Stoudemire (who was always crying to get the ball) and basically too often looking to pass when he should shoot.
That's often what got him into trouble because the scouting reports told guys to play him for the pass and not for the score, so he was too predictable.
I think that he's probably going to look to be more assertive with (no offense) less talented teammates, so his game will be more balanced and efficient, but he will for sure remain a skilled and willing passer. Watch his dish to Okafor for a dunk and expect more of the same.
I don't see the arrogance off the court. It has more to do with his demeanor and off court actions. Of course, I may have misread that too! Either way, I'm glad we have him and I think he'll be very productive for us.
