Numbers are usually tossed around to debate how the split should go for Pacquiao vs. Mayweather....but after get KTFO it's moot point..
Well, as long as the numbers remain this high, there won't be a Pbf/Pacquiao fight (I know everyone knows this). What would cause the fight to finally materialize is if either guy's numbers, or especially both, begin to trend downward. The other consideration is that with the match up no longer in the air to sell each others' fights against guys like Guerrero, maybe now we will begin to see the numbers taper off. Don't know. But can't imagine Pac/Jmm V won't sell well.
Pacman/Mayweather will happen when both have dropped in appeal and stock and trying to get one last payday. That's usually how it works. Notice how willing RJJ is to fight guys these days who he never would've considered fighting back when he was relevant?
Pacquiao & Mayweather will fight when Manny becomes naturally bald and Mayweather lets his gray hair grow big as in the (future) fashion trends.
