If Cotto beats Manny thats going to set up a fight between him and Mayweather ... there's no reason for him to rematch Mosley ... yeah the fight was somewhat controversal but Cotto won early enough that the argument can be in his favor. I read that Cotto stands to make a good 10m + in this fight ... if he does and turns out to win then Mayweather would make him twice as much as that on a waaay bigger stage than Mosley could ever bring. That would bring 2m buys and it would ... be a true superfight against two prime welterweights ... kinda like Tito vs Whitaker ... but I doubt it would be the same results. or Leonard vs Duran ... or better yet ... Tito vs Hopkins
Nope, Cotto deservedly won a good fight against Mosely, and nope, Cotto would be off to face Mayweather should he win.
Like everyone above has said, if Cotto wins he will fight Floyd. I guarantee you that Mosley will pull out all the stunts and do all kinds of crying to try and get Cotto to rematch him, just like he's doing now with Floyd.
If Cotto beats Pac, It's FMJ next. He already beat Mosley. The money he'll get fighting FMJ, the winner of this fight for P4P king, the money he'll generate in his future fights (if he beats FMJ) are too good to pass up.
