I think the Margarito fight he was in shape, but not "Manny Shape", like Ariza mentioned.. his body looked a little softer. The condition he was in for the Cotto fight was out of this world.
Pac is in great shape and 147 (144 pounds) should be if not the weigh-class he's on top of his game ( maybe at light-welter 140 pounders he would look even stronger to his opponents), at welter he should have no disadvantage whatsoever. Now, I have to consider Shane and Manny altogether and the magnitude of the event along... Shane is not just gonna join the party, say huh ah, nice to be here and last the distance like Clottey, Cotto and Margarito. Shane is gonna fight and Pacman should be ready for the bombs that we know Mosley can deliver... It's up to Pacquiao if he's gonna step in, stay and punch or if he's gonna touch him there plenty of times while he's always jumping out and coming in.
