Would Manny Pacqiauo Dominate the UFC Lightweight Division ?

He may have a chance against them if they wanna trade punches with him,but isn't Maynard known for his Lay N Pray? If that's true then he would end up like Toney. And i'm not sure about if Penn or Edgar would try to trade with him or take him to the ground too, but i don't think Pacman would stand much of a chance unless he learns some grappling and perfections it which would take years and remember he's still young, but not that young.
