I can see your points about the $$$ lefthooktothebody and they are valid but 3 things:

Aren't Manny and Ricky both millionaires by now?If not,they are dam comfortable.

If all fighters are going to have this mentality,then rather than face tough guys in their weight classes,they'll jump numerous weight classes all the time.What if Isreal Vazquez had jumped to 130/135,passing over Rafa Marquez.

Manny is going to fight Davi Diaz,win the paper title and we are going to have to hear how amazing he was at 135,winning the title there.DAvid Diaz is an average fighter.There much much more worthier challengers.You're telling me you'd rather see David Diaz/Ricky,rather than Juan Diaz/Guzman?
