Prime:
1. WILT (different NBA then, but he did dominate at an unprecedented level)
2. Shaq (In his prime, I think he wins every matchup against any other center in history - sheer size and tenacity when scoring)
3. Kareem (For me he's the GOAT, excellence for such a long time - in his prime he was just too much, but he did have trouble stopping Reed based on old games. Still couldn't be guarded)
4. Dream (Couldn't be fukked with in his prime.)
5. Moses (In his prime, he was a bucket - plain and simple. If it went into the post, it was almost a sure 2 points - putback king)
6. Russell (Won 11 titles as the best player on his team, but never as the offensive focal point - #2 all-time. I think the guys ahead of him in their primes would've won 11 championships too on his teams - maybe not due to his leadership and unselfishness - but hey)
7. Admiral (Did everything and was the most athletic center that I've ever seen. Ran the floor like a gazelle)
8. Walton (Short prime, but was probably the most fundamentally sound Centers in history)
9. Wes Unseld (Leader, team player and winner. The most important guy on his teams when they won.)
10. Reed (Could shoot the mid-range, play-D and caused matchup nightmares in the favors of championship teams).
All-time:
1. Kareem
2. Russell
3. Wilt
4. Shaq
5. Dream
6. Moses
7. Admiral
8. Reed
9. Unseld
10. Ewing
