Let me be clear. I'm not trying to start a war here that turns into something nasty. But it probably will anyways. Hopefully some good replies pour in before then. I'm genuinely asking what makes Mayweather better than Calzaghe p4p. Hes usually regarded as such. But they're both undefeated. They both have reputations for fighting their best opponents past their best. And it's actually Calzaghe who has the best win over an opponent in their prime. Kessler is better than anybody Mayweather fought in their prime. Mayweather made much more money and was much more well known. Ok, sure. But I mean strictly from a boxing legacy standpoint why is Mayweather better than Calzaghe p4p. Considering the previous paragraph. So with that said what makes Mayweather better than Calzaghe p4p.
