In a match-up made in a fantasy boxing world, Manny Pacquiao would be stopped facing off against Marcos Maidana from Argentina and I will tell you why. Pacquiao has never fought a fighter like Maidana in years. Maidana throws punches from weird angles and that would scare Manny more than ever. This is a Maidana with a trainer now and can jab and cut Manny off who really doesn't use the ring, he throws and steps right, that's it.
Manny Pacquiao would be scraps on the curb, dealing with the pressure of Maidana who's going to attack him differently than he has ever been attacked. This is a whole different monster, one he wouldn't want to face, at this point in his career. Maidana would knock Pacquiao out in about seven rounds.
