I don't think Vince ever had a problem sharing the ball. He just never had much opportunity to play on top teams during his career. If Vince and Kobe had of switched places and Vince got to play with Shaq, Vince would be remember much more fondly.
Vince had bad luck in Toronto with T-Mac leaving. There was no offensive talent there to help him after that. Then he joined NJ where he played well alongside Kidd and that scoring SF but their team had no interior defense or rebounding after their rugged PF of previous years left for Denver. Neither where Vince's fault. The faults were in his supporting cast.
I thought Vince played brilliantly on that Team USA in 2000. Arguably the best player on the team. Either Vince or KG with an honourable mention to Ray Allen who was also brilliant. I reckon that this is the best example of how Vince would play in his prime on a team with lots of talent.
