Wilt and Kareem stand out above the rest. Russell has the championships. I have seen lots of games that all of them have played and by my eye test I think Olajuwon was better than the rest. He played on some putrid teams which didn't help him. Obviously Russell and Kareem played with some of the all-time greats and Wilt had talent when he won his championships as well.

Oscar is a tough study. One thing I count against him is that he was never the best player on an NBA Championship team. He won a title, but Kareem was easily the best player on that team. He put up some amazing stats on some pretty bad teams (they won two playoff series in Cincinnati with Oscar where he played the first 10 years of his career). Is that a little bit of Russell Westbrook? I wouldn't go that far. He is a great player, but I don't put him on this list.
