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?
Nope, JDS's only chance is to land another wild haymaker. Other then that he's got nothing on Cain despite the outcome of their first fight. Sorry if the truth got you upset.
And yes you can put a lot of stock to how badly JDS got beat up, his face was literally broken and his soul was stolen. That's what happens when you run into a superior fighter and don't have all the necessary tools.
