His mind is fine, his chin is the problem, he looked great against fedor, the dude tonight, but once they tapped the chin it was lights out. Maybe if he got rid of those stupid twilight teeth things he wears and switch to a real mount guard he would be fine.
Anyone getting hit like Arlovksi in the Fedor and Rogers fight would have gone to sleep just like Arlovski.
It's his guard! If you have a solid guard, that protects your chin = no problem for chin.
