Who do you think is the greatest center in NBA history? Why?

I do agree that it would be Bill Russell considering that he won 11 titles in the 13 years that he played for the Celtics. I mean, that's over 80% of your NBA career winning the championship. That is so unheard of. I do think however that it would be remiss if we forget about George Mikan, a player who came in before Russell and became a star in his own right. There was a time when teams would just hold the ball just to make sure that he doesn't get a shot [that was the time before the shot clock was invented]. He was that dominant for the Lakers back then. I'd also just to sneak in Tim Duncan here. He's been so fundamentally sound and ever since he started his career in 1998, he's been so good and respected, that when he averaged 19 points and 11 rebounds last year, many considered it a bad year. That's what most people consider to be a career already.
