pac-man would have to fight an extremely disciplined fight to even have a chance.. he throws a lot of fast punches but he leaves himself off balance often, and i can see floyd jumping on that the whole fight.. pac's defense is his offense really, and if he can't find floyd too often (which i don't think he will be able to) then he's going to have a tough time defending mayweathers counters.. Pac has a ton of heart so i'm not sure if floyd TKO/KO's him, but definitely a UD for Floyd.
