I don't think that will happen. Roach only wanted the fight as de la Hoya had to kill himself to make weight - Freddie knew this.
If Pacquiao wins then don't be surprised to see a 3rd fight with Marquez, or a return to 135lb.
Mayweather Vs Marquez - I am skeptical about that happening.
Pacquiao will never fight Cotto, Mosley or any other natural 147lb'er - he's too small against a healthy welter - Freddie knows this too.
Perhaps a fight for Pacquiao could be Velero.
In my opinion, Floyd isn't coming back - these people are blowing smoke up your arses.
Hatton KO10.
JUST MY OPINION THOUGH!
