Exactly, after Khan theres no one else so why wouldnt he want the Pacquiao fight, he wants to keep makin money. Oh yeah he cant because Pac is gonna be busy rematchin the same people over n over again, wouldnt be suprised if Pac-Bradley n Pac-Cotto become trilogies, dont even wanna guess how many Marquez fights there is gonna be
Canelo vs Mayweather would be biggest money fight in the history of the universe. (Since Mayweather-pac ain't never going to happen, ever)
The winner of Golovkin/Pirog. That's all that's really left and MW, and he sure as hell can't go back down to 154.
