IMO Pacquiaos power is the same, he just got the right hook in hes arsenal now. He couldnt KO, DLH, Clottey, Cotto, Margarito. Even had trouble with Diaz after clean shots, and Marquez will just get back up. He's major advantage is, the bigger the opponents the slower they are, fast punch combos that land with power will sure hurt any opponent.
did you see that fight? lozada gave up and kept holding so the ref stopped it, malignaggi looked like **** ,lozada even worse it was not a TKO
