Diego is a fucking animal. There's is nothing you can do to that guy to make him mentally quit. The beating BJ Penn put on him proved that. He's gonna keep coming until the final bell or the doctor puts an end to it. You're gonna have to choke this guy unconscious or knock him unconscious to stop him and no one has figured out how to do that yet. If he's still conscious, he ain't gonna quit.
