JMM is the undedog vs. Both Men it's that simple end of...
What more do you need.

Any welterweight or less beating Cotto and Mosley would be the trump card. They are big welterweights and Cotto is basically undefeated having taking on all comers. Mosley, well he needs no explanation.

Marquez beating Mayweather and Pacquiao easily is the most impressive.

Number 3- Pretty Boy ending his layoff and beating the number 2 and 1 p4p fighters and then going to 147 and beating Cotto vs Sugar Shane if it ever happens.
