D'antoni's whole theme was based on him not prejudging the players. Well he basically already did that when he decided Duhon had to be brought in here because of preconcieved notion, that no one on the roster would be able to distribute. Steph has played better in less time. Let's just be honest.
But that being said, Duhon can run the system. He just needs imo to make things happen a bit more on his own. And in time, that may become easy for him. Or not. Hope so though. We need it.
