I dont know, I think those who really hate on him may simply always do so. One thing I do think would benefit his legacy a hell of a lot, and silence even his biggest detractors, would be if he won a very close fight, and battled back to do so. If ppl saw him hurt, in trouble, to the point where he had to dig deep just to survive the round and keep fighting, then I think that would change some peoples minds.. Not mine, and I know for one thing Mayweather would never take unneccesary risks in the ring(which is why alot of ppl dislike him, in truth). But If he met the right opponent who could bring out another side to him, who could hurt him and make him trade a little bit, it would be basically the one thing we haven't seen from Floyd yet. Sure, Castillo I was a razor thin fight and many thought Floyd deserved to lose, but it was hardly the scenario Im describing. Floyd was never actually hurt or in danger of losing big, he simply let his foot off the gas in some of the middle rounds and waited too late to start landing big shots. It was still very very close, but he didn't close the show or overcome adversity in the fight. And it's no fault of his really, especially considering how effortlessly he won the rematch. Take Pernell Whittaker, for instance, and for one who can be compared to Floyd, had overcame adversity alot more in his career then Floyd has yet, plain and simple. He was robbed overseas against Ramirez, got sloppy and dropped on his ass by Roger Mayweather in a great fight that he came back to win via stoppage, he was royally screwed against Chavez with the draw, was in a fight all the way through against Buddy McGirt the first time round, had to come back from early KD's and a huge point defecit to stop Disobleys Hurtado in the 11th, then went on to lose a very contraversial fight with the Golden boy, took a man sized beating as a shell of himself against Trinidad... Those are all things that make people respect and appreciate a fighter, and Floyd hasn't had too many of those moments in his career. Now couple that with the fact that Sweet P still doesn't get his respect from alot of ppl, and many don't even know who he is, and I don't think its that surprising that Floyd is on the receiving end of alot of hate, and may not be appreciated in the future either. Just the way it goes, those who watched his fights will always know he was a great fighter.
