Geepers if KOing a 37 year old Holmes who hadn't fought in 18 months was his biggest win? Doesn't say a lot does it? Not saying you're wrong, just that that's not much of a biggest win when discussing great fighters.

I think most would say Mike Spinks. Yeah he was a blown up 175, but he WAS the lineal heavy champ. Tony Tucker deserves a mention. A fine heavyweight.
