I have to disagree here. Cain certainly caused damage, he certainly was dominant; but he's the one with the broken jaw and the longer medical suspension. I think if Cain abandoned his strengths and fought JDS's fight, he'd get KO'd again. He's not a better striker than JDS, not by a long shot. But he's a more complete fighter, and thus he wins.
In the process of him allegedly fighting safely he absolutely dominated JDS and caused him pretty significant damage. So JDS should be happy then cause if that's Cain fighting safely he might have put him in the hospital for a lot longer if he was more aggressive.
