Ah, khaldun007, don't you love excuses? Yes you do. Penn lost to hughes, end of story.
But backt to the topic at hand. Penn has evolved much more than Pulver recently. I think he is better than the first time they fought actually. he is more experienced and more well rounded. He will win by sub or ko. I put sub but that is just slightly more likely. It doesn't really matter. He'll still win.
