Certain fighters need to hang it up

Over the years, we have witnessed some of the greatest fighters to ever be in the sport of MMA. Whether it was in the UFC or Pride they have entertained us for years and put on performances that we will never forget. Only things with these fighters is that they do not know when to hang it up. Am I the only one who is tired of seeing some of my all time favorites take a beating and still want to keep fighting. Why keep messing up your legacy when most fighters can be like George St. Pierre and leave knowing he beat everyone he faced and is one of the all time greats. Recently fighters suffer at the hands of humiliating losses and continue to hurt not only their legacies but their health. As dominant as they were in their hay day they just lack the “punch” they once had and continue to turn us as fans off. As much as we want to see them hang it up they still continue to fight and we still continue to support them. We may never see a prime great in their late 40’s and I feel fighters need to give it up while they have a chance and risk messing up the fans view as great figures in MMA history.
