 You know, they're just done. I think of a guy like Vince Carter. Vince Carter in his prime was just a monster out there. But he wanted to keep playing. And he knew he wasn't the man, but he played for several years just being a guy out there. Most superstar, most guys that call it quits can still play pretty damn good. They can still probably be on a roster. But they just kind of know, all right, I'm not the best anymore.
