Willie Pep went 63-0 before he lost his first fight. After that defeat he won another 73 in a row!
Those guys boxed up to two times a month. Pep had 241 fights in his career. On bad days Mayweather has been run close by B level guys like Castillo and Maidana. If he boxed more regularly and against the best guys around, like they did back in the day, there is no doubt in my mind that he would have some defeats to his name. Ironically his legacy might have been greater in that case.
Yeah there's definitely a case for it, the problem is with all sports is that they've changed now and there's no need for him to fight that regularly and there's no logic in doing it for him....a lot of older fighters are in a bad way now due to the amount of fights they had.
Mayweather's appeal to sell fights is pretty much the "0" in his record. I actually do quite like watching him fight because I think it's good to watch someone that talented and at that level be so good at something but I know it's not for everyone. His whole selling point up until the Pacquiao fight was people probably wanted him to lose, now he can sell himself on it being his last fights and the 0 doesn't matter as much as it did.
Mayweather has (or had) the ability to fight aggressive, the Gatti fight is an example of it when he put on a masterclass against a very attacking fighter and stopped him, the defensive style works very well for him and people can't beat it but if he has to go in a fight he definitely can.
Floyd Mayweather has fought all the best in his decision, maybe some past their best but he still beat them, the argument can be made he fought a few of them too late but I do think he'd of beaten them all in their prime anyway...of course there's no way of proving this.
