It would be a good thing. Mayweather has been slipping a bit. I expected him to do a Gatti-like performance against Cotto. Even though it was a wide UD, no way Cotto should have been able to hang with Floyd. If Floyd got humbled a bit, I wouldn't want to be his next opponent. As big as Floyd's ego is, he would train like a maniac.
if floyd lost, which i can't see happening if he just boxes, or went toe to toe imo. he'd win the rematch, he has way to much ring iq and this time he'd know what RG is about.
The question is more geared to how much interest would you have in those fights that are listed, not what Mayweather's next move would be.
nah, not really, Floyd has huge heart, if he got knocked out silly, expect him to come back vs RG, then he might retire - realising he is getting old, dont expect floyd to retire from a direct loss for another couple of years
