I think he wants one more fight and one more fight only. When you think about it, he went out the champion, and Fedor was the Pride champion. so he probably see fighting Nog as a no-win situation. In his mind the best should fight the best, not go through an elimination bout. With that said, I think he could bean Nog, but I also agree with him to some extent. He shouldn't have to prove anything and should fight nobody but the reining champ in another org to unify.
