Yes. But I fear Mosley's power will be too much for Pacquiao. Pacquiao's head kept on getting snapped back by Cotto and even when Clottey punched at times. I could see definetly see an upset.
I think Roach believes Mosley is too big for Manny, and would likely try to introduce a catchweight. But I think Pacquiao would want Mosley if he beats Floyd.
