Fighters I think Pacquiao could KO due to their horrible Glass Jaws: Roy Jones Jr Fraudley Rahman Wlad if he could reach his Chin.
Let's get real here. Audley is a 250 pound, 6'5" genuine heavyweight. He'd only need to land a half dozen punches to flatten Manny. Audley only lands 2 punches in the fight, Pacquiao wins UD.
Im going with Audley, i think he overwhelms Pacman with his amazing work rate and killer instinct and KO's him...
Harrison would not put up as much of a fight as Valuev (By the way does anyone know of a pic where Pac and Valuev are together? just for the humor value of it)
