I didnt get a good look at the groin kick, but the way he hesitated before he fell after the head kick made it seem like he was over selling the shit outta the whole situation. I cant stand Aoki either. I think he is one of the most overrated fighters on the planet. I would like to see him fight some of the top lightweights from the UFC. I wouldnt give him a snowballs chance in hell of beating BJ, Florian, Maynard, Edgar, Griffin, Huerta, Sanchez, or Guida. I feel like a lot of the lightweights in Japan are overrated because they fight lesser competition. Just my two cents.
