Joe, you're mostly right, and that's why I said that I find it hard to compare him to anybody in the NBA. You are absolutely right as far as pushing the ball goes. Vujanic LOVES to run. As far as Marbury dominating the ball, it is really not his fault that other stand around and watch. Even if somebody is dominating the ball, other players have the responsibility to move without the ball.
Now, having said that, judging from your description I would say that you've probably seen Milos in the Olympics and/or in the World Champioship. He has a different role on the National team. When he played for Partizan, he was always looking for his shot first (being by far the best player/ scorer on the team.) I haven't seen him this year yet, so I am not sure what his role is now.
See, my point is that he can do BOTH, he can push the ball or play in half court set. He can distribute the ball and he can look for his own shot. He does all of this equally well, which is why I think he could contribute to the Suns or any other NBA team.
One thing he is extremely good at is driving to the hoop, drawing opposing big men, then passing to his teammates for easy dunks/ layups. And I have to mention that he is a very smart basketball player, just like Divac, Sabonis, Bodiroga, Marchulionis, and other great European players.
