This is a business ,that if you stay too long ..you are going to lose...the longer he stays in the sport someone will beat ,but as long as he continue to win ,the chances of someone beating him becomes great each giving year...After the Mosley fight in which I think he will win ..he should fight Pac ...Win that fight and retire forever. Im a big Mayweather fan ,but time catches up with everyone...and as long as Paul Williams is around ,he is the only fighter out here today that can beat Mayweather at 154....Point Blank
