Bill Russell was arguably the best center ever. You could even make the argument that he was the best basketball player ever on planet earth, if you really wanted to. He was certainly a winner.
I'm not much of a historian (maybe somebody could look this up) but if I recall correctly, he led his San Francisco college team to an undefeated season and the NCAA championship, then didn't go straight to the NBA because he went to the Olympics instead, where he led his team to the championship. After that he joined the Celtics mid-season and (perhaps) they won the NBA championship? Not sure if they won in his first year or not.
In any case, Russell's teams won basketball games and they won championships. Everywhere he went.
I like Shaq, and he was certainly an awesome player in his own right, but he's no Bill Russell. Anybody who says Shaq was better than Bill Russell is either too young to know any better or on some kind of illegal substance.
"We are not provided with wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can take for us, an effort which no one can spare us, for our wisdom is the point of view from which we come at last to regard the world." --M. Proust
