and every time you beat a boxer, you got all his wins to add to your wins, who'd win out of Hatton and Mayweather? And who'd be the best of all time.
You mean before they fight? Mayweather wins it and it's not even close. Pretty much everyone that is on Hatton's record would also be on Mayweathers, but Floyd would have a bunch of guys that Hatton does not. (although both guys would teqnically have wins over the likes of Ali, Holyfield, RJJ etc)
I mean like If Mosley beat Hatton he'd get 43 points, but if he beat Mayweather he'd get 38. And Hatton is continually told he fights over the hill fighters with glittering careers and legacies but who are nothing by the time Hatton gets his hand on them. Tszyu, Castillo, Phillips etc. A lot of FLoyd's fighters didn't have more than 25 wins when he fought them.
