Are they on good terms these days and if so do you think this could happen? If it did do you think it would have any influence on the fight? Mind games with Pacquiao??
Personally I would love to see it. Imagine Floyd in the ring with Shane and Manny, calling Pac a cheat and/or a coward before fighting his scraps. I don't support either side... But this would be a huge incident.
The last time Mayweather begged for a fight was in 2006 when he wanted De la Hoya and Mosley badly, Nowadays he is the De la hoya of boxing, He would probably need to lose all his money for us to see him in the ring these days.
Doing that would lead to an increased media spotlight on Pacquiao vs Mayweather, which Floyd simply does not want.
Mayweather does not want to, and will not, ever, ever, ever fight Pacquaio. The fight will not happen. Forget about it and move on.
