Honestly, Mayweather. But if PacMan is looking for WW glory, forget the catchweight opponent draining crap, fight at WW, and challenge the top guy, which is Shane at the moment. But PacMan shouldn't risk his health at 147 or risk Cotto's health at 144. Mayweather is the fight to make for him, Cotto and Mosley should fight each other.
I would say Mayweather, but I want Mayweather to get one fight out of the way so he has no excuse for why he lost
to be Honest the Big 3 welters need to say this... We will not move down to fight manny. If Manny wants to hide in 140 let him. The big fights are at 147. if JMM can move up to get a big fight so can Manny. Cotto Shane and Floyd Can fight other fighters at welter or even eachother. Move On. Pacman will come up he wont let roach hold him back forever
as everybody have said...PBF but since that dont seem to be happening this year...if i had to choose id have to say Cotto and they should move the fight by end of December...that cut was nasty...then Mosley and PBF in 2010 and he can call it quits if he wants P.S.: i dont expect him to win these fights but its still worth seeing it to see if he could
