Clearly, Woods didn't think the mental mistakes were the only things that cost him this Major. The one big question that remains to be answered about Woods is when he will win again, and it's important to bring another sports perspective into this equation: halftime adjustments.
Woods knew he wasn't making putts above the hole, but what did he do to prevent landing the ball above the hole on a consistent basis? Yes, the course was nearly impossible to play on certain holes. But if Woods knew he couldn't hit putts from above the hole because it was way too bumpy, he should have adjusted his strategy and swing to accommodate for that.
It's what great coaches/players do when one thing isn't working - find something else that does. Until Tiger does that, he's not going to be at the top of the leader board when the tournament is over.
