If mayweather fought world hunger and won it wouldn't make any difference. He can do the same thing joe calzaghe can do at this point. Nothing. Some like him some don't. It will always be that way. Floyd would be a fool to get back in the ring although i think he will. No one wants to see floyd fight they only watch to see him loose, the last thing i'd do is play the fight him..no no wait fight him, ok you beat him but i bet you can't beat this guy etc.....
