I think people really underestimate Jones' grappling. His active unorthodox striking style coupled with his ridiculous reach is more than enough for any fighter in the UFC. I believe in a year from now he will still be champ. He is still a couple years from his peak so he only gets better.
I could see this match happening next year since JBJ will have cleared most, if not all of the UFC LHWs out by then.
