As stupid and idiotic as this sounds, I wonder if he would ever grow bored of winning, day in and day out, and just simply blow an FJ!, or not bet enough, or do something to end his reign. Mind you, this is not something that I want him to do, I enjoy seeing him as champ, but it's something I've wondered about.
Michael Larson, as we know, ended at $110,237 but he could have kept going if he wanted to - he chose to stop, as best I remember, and passed his spins. How much further he could have went, I guess, depends on if CBS would have stopped him.
