I know alot of people are sold on Calzaghe, but to me two fighters who would have beaten him easily enough are Thomas Hearns and Roy Jones Jr. Tommy would have had the jab and right hand and Roy would have been too quick and landed great punches. Interestingly these two guys are the same two who beat Virgil Hill first. Even now I think Roy Jones could do well with Calzaghe. He would have to box and use his speed, but Calzaghe couldn't deal with Jones overall skills.
