like mentioned by most smart boxing people....mosley is too fuckin strong and he is faster than floyd... the first 3 rounds of the fight, mosley comes at you hard...and floyd has never been hit with power like mosley's... mayweather hasnt been challenged since castillo (which i think would be an interesting fight now) ... anyway, bottom line ... shane would murder floyd to the body with left hooks and knock him out with a big right hand....fuck mayweather and his skill...
