Styles make fights...If anyone has a shot at getting Mayweather it's Pac. Manny will chase him and force him to fight his fight. I would rather see Pacquiao get KO'd chasing down Floyd and making it a fight rather than watch Mayweather just run the whole fight.
If this fight is close, I wouldn't be surprised if the judges gave it to Pacquiao...A second fight would be big $$$! If Floyd won that fight, a rubber match would be huge and I wouldn't be surprised if both fighters retired at that point regardless of the outcome!
