If he doesn't end up in the UFC it won't mean too much. Although we could get a few entertaining fights outside of the UFC. But it would be nice if he showed back up in top form and made a run at the UFC HW belt.
Technical Primates -Werdum is way better.Catlin - He will only tarnish his legacy even more if he returns.
Unless he beats his opponent. Which maybe, just maybe, is a possibility (given the fact that he's probably the best HW of all time and everything)
One of my all time favorite fighters. I don't want to see this honestly. Only way I could get stoked about this is if he moves to LHW.
Just can't really see him doing well at HW anymore.

That doesn't make him the greatest Middleweight of all time.
