The undefeated thing really doesn't mean anything, given that he retired when he was still on top.
Joe Calzaghe never lost; Ezzard Charles lost 25 times. Which guy is the greater fighter?
Marciano is an ATG in my book, but just barely. I rank him around #10 or #11 on my all-time heavyweights list. P4P he maybe cracks the top 100.
