Mayweather had an excuse not to fight Margarito and Cotto because they lost.
If Pacquiao loses to Hatton, and Mosley loses again this year,
Floyd will have an excuse of staying retired because he's waiting everyone to lose so he will have an excuse not to fight them.
He can say I'm the best fighter in the world while the Welterweights are destroying each other and Floyd doing nothing and wating everyone to lose.
Now he has all the Excuse not to fight again.
