It would be a big money fight for Mayweather. I've always thought he's beat Manny. But I still think with the fans that Pacquiao has it would be a large $$$ fight. Don't hold your breath on it ever happening.
I actually think it will happen now... I reckon FMJ-Khan gonna happen first and then FMJ-Pac and its still gonna be a megaevent.
Fight will be made if SHO has any say, they need to make money and it's the last big money fight left. Pac just has to do his part and dispatch of Rios convincingly. Pac is open to it. It will happen within four fights.
