Although Calzaghe didnt really achieve a great deal in fighting names, he did prove his worth by being so dominant for so long. I think if he was the same weight/size as the others he has the ability to beat anyone.

Lewis fought some names but didnt really have a dominant period where he was thought of as unbeatable. He got KO'd by McCall as he was coming up, then got gifted a decision against Mercer, he cryed about the first Holyfield result but the remtch was a robbery against Holyfield! Then he gets knocked out by Rahman. His best win was as he slupmed in to his stool exhausted against Vitali.
