I really believe in Nate and I think he can win this fight either by TKO or UD. I've never seen Marquardt in a bad fight. He has really grown on me lately, probably one of my favorites.
Maia is a stud, he will pose a threat to anybody. I'm not counting him out completely because it only takes one mistake to get caught in a sub...I just don't thik Nate will make that mistake. He's an extremely well rounded fighter - something that Maia has proven not to be.
