He HAS proven himself. It cannot be doubted. He HAS made "enough" money. He has made his name one that will be remembered. Honestly, I think he should bail. If he continues to fight, the potential revenue he could make in the future could drop a lot if he gets beat up a couple times. He got beat by Nate, but he won the rematch. That didn't hurt his image too bad. Got beat by RJJ. But did last 8 rounds. His image is still not hurting. But he has to retire or fight. And if he retired right now he could still stay relevant in other areas. If he fights and losses, well, look at how relevant RR is nowadays.
