Pacquiao will batter Diaz no question, Pacquiao even though he is an aggressive fighter has some good boxing skills, and like Rains already pointed out is an underrated counter puncher, plus he has a lot more in his arsenal than the old version of Pacquiao jab, jab, straight left. Pacquiao has got some weaknesses that a good boxer can take advantage of but an aggressive brawler with no defense and no real skills, isn't going to trouble Pacquiao at all. Diaz isn't gonna know what has his him come Saturday night.
