^I agree he would have had problems finishing it on the ground. He simply didnt have the grappling skills to hold even a zombie JDS down to land much GnP to finish it. But on the feet he had PLENTY of oppertunities to finish it, and probably could have. JDS was against the cage trying to Anderson Silva his way out of shit and was just getting smashed. Cain then switched to wrestling to avoid losing stamina and risking getting tagged. If he had kept it standing, I think the ref would have stopped it, regardless of JDS' heart.
