Marquez is supposed to lose to Floyd. Cotto should beat Pac (even if i hope Pacs wins). Considering that and Marquez already being p4p #2 he should easily be number one if he beats Floyd.
It would have to be Marquez man.
The fights afterwards would be more interesting though...
Cotto-Mayweather at 147
Pacmaneth-the juan and only at 140...(or less I guess)
let's hope it happens
