You really cant say those are the "Centers of his time, really. They were all pretty much on the way out or in the prime of thier respective careers when Shaq and Zo entered the NBA. The only centers I think talent wise you can compare him to are Mutumbo, who is almost his equavalent on the defensive end, if not a tad better, and of course Shaq who there really is no stacking up to anyhow. But in his class of centers, which was very light IMO, he was one of the more dominant centers. And alot of people seem to forget that he was the backbone of the Hornets team that shocked the world when they took out the Sonics in the first round of the playoffs.
I think your mean Dikembe Mutumbo and the Denver Nuggets when they stunned the Sonics at the 8th seed!
