Ken's got that thing about him.... he's like a magnet for controversy. He doesn't accept defeat well.
-He tried to take back his tap against Royce at UFC 1.
-He didn't do anything- regardless of the rules- at UFC 9 and complained about the decision. (Severn)
<mma2>
-He quit against Fujita after dominating him. He claims to have had heart issues, but I think he had cardio issues and was maybe a little discouraged when he couldn't finish him because he'd seen Fujita/Kerr.
-He was smashed by Tito Ortiz but furiously protested the stoppage, only to suffer an identical result 3 months later.
-He turned his back and fell into the ropes, as Sakuraba pounced on him. He proceeded to walk in the back and go on a tirade about PRIDE protecting their guy. He was furious.
Even I thought Royce's nut shot hurt him, but- just like with the boy who cried "Wolf"- I already quit listening to him at that point.
