Hopefully Cro Cop can comeback strong and whup some ass in UFC. I've been a fan of his since he koed Bob Sapp. Mirko shouldn't be physically shot and i don't believe he is. His main problem in the UFC it seemed was a lack of motivation and desire to fight. When you don't have the desire to get it on and fight your performances will suffer, and that is clearly what happened in his brief UFC stint. I do believe Cro Cop at his best could come back and be UFC champ if he can perform like he did in his hey day.
As accusatory as that statement may be, the fact that many former Pride fighters have not fared well or, have not fought at all(155lb class) since Pride closed down and went to the states. With testing not being done in Japan, it is very unlikely that most if not all the former elites were performance enhancing drug-free.
