I'm going to be rooting for DC, but I think Jones will win. There is no way DC will "destroy" Jones. Jones's wrestling, TDD, striking, muy thai, and length is way too good for anybody to "destory" him. Not even Cain, and I think Cain would win in a fight against Jones.
DC has a chance to get Jones to the ground and use some nasty ground and pound but that will only happen in a round or 2. I don't see him riding it out to a decision, because Jones wrestling is too good to let that happen for 5 rounds. DC striking is questionable but his grappling and wrestling can tire Jones out. It's a very interesting fight. I honeslty can say I can't wait for September 27th.
