Although I am not a mayweather fan, and don't completely agree but the degree of his race does play a major role in his hype. C'mon people him being asian is bringing some added hype. People become so nervous and scared when race is mentioned but he's not being a racist, he's brining light to the fact.
He is an exceptional ball player and has game, however, his race does add some fuel to his fire. Now don't take this the wrong way, his story/journey and play have been contribution but to dissmiss his race is just foolish.
