Feel free to bump this if I turn out to be wrong.

Tiger isn't going to win again (with his current style of play). Yes he's just out there hacking it around for his foundation but I never got the sense that he was taking it easy. He was going full throttle with a bad back. This tells me that Tiger will never learn to dial down the aggression. Not a good sign for someone whose career hangs by a ligament.

If he hit driver at 75%, or took an extra club on his iron shots, played it more safe on his body, I think he's good enough to win some tournaments. But it looks to me like Tiger thinks he can win majors by gutting it out, back or no-back. I think that style of play will work against him and he'll never win, retiring from golf around age 40.
