Look, man. I think that this is one area of the fight game where Pac can really make a difference in fights. He has a devastating left hook to the body, but he's not committed to the body attack. In Marquez IV, a body shot made Marquez do a little wounded gazelle dance. Against Brandon Rios, a Pacquiao body shot had Rios bending at the weight pretty dramatically. Same w/ Margarito, who dipped low and couldn't guard his face after Pac landed the kidney shot.
You do realize that Pacquiao fights out of the Southpaw stance, yes? Or did you forget about that little detail? Lol...
