Should Mayweathers stamina not be judged agsinst a similar sized man, like Mighty Mouse? I think his stamina matches up better.
well u can even compare them to like the klitchkos and others at heavier weights..
but still they all get injured and tired seemingly 24/7
face it guys... UFCdoesnt produce great athletes, compare them to people like Federer Kobe Alexander Ovechkin Pacquiao pretty much every other sport, for a sport that doesnt have much stops [ex- football baseball] they really have crappy endurance
