I think the reason why these rumors has been coming out is because of the delay in the signing for the fight. Mosley is desperate to have this fight that he may accept whatever terms Mayweather will put in front of him as long as they're not ridiculously insulting. They are both under GBP so the negotiations should run smoothly. And Floyd, being noted for his grandstanding, would have immediately grabbed the opportunity to take the limelight away from Pacquiao by making the fight happen. What then is holding it up?
Like what i said in the other thread, I also sense that Mayweather is going to sit out this fight (and no, I'm not a psychic nor a Jedi). If Manny loses, then he would attain the P4P title without even fighting. If Manny wins, then he should accept the fight as per Manny's terms (blood draw 24 days before the fight). This is a win-win situation for him.
If Floyd does decide to fight Mosley then I'll give him credit for that. But until then, let the rumors continue.....
