curious as to why you would think he is done? YE Yang loss? Scandal? or just a hunch?
One of the parts of the game I have studied at length is the mental game, because of its importance.
When Tiger wrecked his car, and in turn his private life, it messed up a certain "harmony" in his life (a word I have used countless times before to describe this). Therein was created an imbalance within his life that has caused him much trouble. Since that day, I told myself and everyone who I get into this conversation with that he won't win another major, or return to his former dominance, until he stabilizes that imbalance and recreates the harmony in his life that made him so successful.
I never said he wouldn't win again, because that's just asinine, but I believe he is done in majors until the aforementioned is attained. He may win this tournament, but that imbalance created a weakness that other Tour players have recognized, which is why very few feel mortal against his immortality. That's why I believe he doesn't have this tournament in the bag. If he fires a 71, and one of the players at 11 fires at 65-66, it's game-set-match.
