First Cormier needs to fight his horrible diet. Then he needs to fight about 30 pounds of fat. After that he needs to do a test cut to see if he can even make 205 with his "bad kidneys". After that, if he makes 205 in a test cut, he can start calling out people.
As far as right now, Any match up with him at 205 is nothing more than a Rickson vs Fedor Fantasy thread.
