Can Pacman dominate Lighweight division?

If Manny can beat Diaz convincingly.... no doubt that he can dominate this weight division (provided that he will not lose the discipline that he is currently displaying.

Manny Pacquiao has reached his peak. He's just in his late 20's and has may be a good 5 years of profitable fights. I believe he can dominate his weight division. As long as he keep himself humble enough, train hard, work hard, and help others, he will continue to win. But mark my word right here. Once he think of himself as somebody who can beat anyone at anytime, and starts to brag, that will be the start of his downfall. And you can then right down, "The Rise and Fall of Manny Pacquiao."
