Unless someone uploads all the martial arts and appropriate skills straight to JDS's brain like they did to Neo in the Matrix to fix his nonexistent MMA skills he does'nt stand a chance other then landing a lucky punch in my opinion.
In other words JDS needs a miracle. Cain by vicious beating again, probably even more worse then the first time.
Cain's a very slight favorite in the next fight IMO. People need to realize that heavyweight fights are very rarely close, and the first guy to land something big usually wins. You can't put too much stock into how bad JDS looked for the majority of the last fight. Remember how easily he stuffed Cain's takedowns at the beginning?
