One list is as good as another, I guess. It's all just opinion, but I don't see how Holyfield can be rated above guys like Whitaker or Chavez (or Nelson or McCallum, for that matter). Yes, he embodies the true warrior spirit and was exciting to watch, but that doesn't make him the best fighter. Just an exciting one. His career as a heavy was far too sketchy to have him at no. 1.
Just my $.02.........
