I've been a fan of MMA for a very long time. Before there was the UFC Brazil and Japan had their own little organizations running early forms of MMA bouts.

Daniel Cormier did say that he was hanging up the gloves by the time he was 40 or so. To be honest if he walked away right now, it wouldn't look bad on his part. Years of punishment and head trauma is catching up.

He was a dominant heavyweight in other organizations, and a lot of current fans don't know that. He moved down to light heavyweight because his teammate, Cain Velasquez was claiming that division.

The only tarnish on DCs resume is the 2 losses to Jon Jones. Mind you that Jon has failed for PEDs and Cocaine usage in both matches.

There will always be a dark cloud over DCs career, but by all fairness, there are rules and Jon Jones failed both times. Therefore, DC has nothing more to prove. If he bows out now, there would be no shame.
