Russell didn't beat Wilt. The Celtics beat the Lakers because they had the better team. I don't know if you ever saw Wilt play but he was way ahead of his time. Teams use to triple team the guy at times. He averaged 50 pts a game. That is with being a poor free throw shooter. How many championships did the Big O or Magic win without Jabbar? Hakeem use to struggle against Mark Eaton.
Hakeem was a great player but their is no way in hell he could have stopped Chamberlain. Hakeem was probable more like 6'10"-6'11. Certainly Hakeem is in the discussion regarding best centers but I put him 3rd or 4th behind Chamberlain, Jabbar, Russell and Hakeem. Hakeem's stats are not even close to both Jabbar and Chamberlain. To say Hakeem was the best defender is ignoring Russell.
