I can't really see it.. Not with the angle that the 24/7 series has taken in trying to make a character out of him... This fight is supposed to be a shot in the arm to boxing, if it really draws some new fans to the sport, it would be a real shame to see him just pack up and leave after he wins.. Maybe his saying he'll retire is just further hype for the fight etc.. I could see him insisting he will retire when he wins, and then having a very brief hiatius before announcing he will fight again.. If he wins this fight in a convincing and entertaining fashion, he will have reached an entirely new level of stardom which he has never experienced anything like, for all his abilities... I can't see Mayweather as the type of guy to just abandon this, he's never been in an event like this before, and he obviously want's to be a star who is in the public eye.. It's probably much easier for him to talk about retiring than it would be to do so, should he shine in front of so many millions tomorrow night.
