The difference is not that Oscar was weight drained. Its all about Mosley being a complete beast at 147 and not looking like anything but. Yeah he has gone up in weight but even coming down he looks amazing at 147
If ever this fight would happen and pacquiao would win. These people who are saying that mosley would K.O. pac handily would again make excuses and probably will say that mosley is old and shot, and that the younger version of mosley would annihilate/destroy pac.
Mosley is 37. I want to see Pacquiao fight a young elite fighter, no more old men unless it's JMM, who deserves another shot at him. Let him fight Cotto.
