Mosley from 130 up to 147 would destroy Mayweather. Â Everybody know that "Joy" didn't really have a good chin, and Shane had dynamite in his fists, he would have beaten Mayweather in more convincing fashion than Ray Leonard did. Â Mosley'd probably beat "Joy" 's son too, from 130(because he's not there) to 147(too high) But at 135 Mayweather would take him.
