Vince isn't in the elite three because he hasn't one a championship. Kobe has three, Wade has one and a finals mvp, and lebron can be excused because he is still very, very young, and will certainly win one within the next 5 years.
VC is not great because he can't will his team to a championship. If you look at his current team, the duo of Carter and Jefferson could certainly be compared to Jordan and Pippen, with the exception that the Nets have one of the best point guards of all time on their team. So, in that regard, the Nets are more talented and still don't have anything to show for it. That is why VC is not great. Jordan in his prime could have willed that same team(if he were in Vinces place) to a championship this year.
