[1] What ATG ranking would you give the incredable weight jumping Pacman if he was to beat Pretty Boy ? [2] What ATG ranking would you give the unbeaten, unbeatable Mayweather if he beats Pacman ?
They will most likely never fight or it will be a long way down the line at least a year plus. Pac will fight Cotto next. Lets see if he can win that fight. Arum will avoid Mayweather like the plague, because he makes a lot more money matching his fighters with each other.
Depends on how good PBF looks after the inactivity. If he has one or two so, so fights and then gets beaten by Pac many will claim that PBF was past his prime in the fight. If PBF puts on a couple of good perfomances and then gets decisively beaten by Pac it will be hard to argue that Pac isn't truly great, the greatest since Duran. For PBF it would be a very good win, but people would always be quick to point out that Pac started out at flyweight when discussing it.
