Cain is like a Mach 3 version of Randy Couture. Quicker, better cardio, and more power. Randy used to break people, and although Junior didnt quit, he looked broken after the first round. Similar to the syliva randy fight. The recent fight was like a mirror image of that couture fight only with latest and best mma fighters dueling it out.
A fully fit Cain could hold onto this title for years, junior may have met his match.
