I respectfully disagree. I understand your surprise with Tigers' collapse on the weekend, but what about Bay Hill and Muirfield? That swing is efficient, compact, and very effective. He was 2/12 with bunker saves in the U.S Open; how many strokes is that? His short game lost him the tournament.
He played bad on Saturday again, lost his momentum. I wouldn't call that a swing issue considering it has been a recurring issue for years. Complaining about his swing is like complaining about the split decision for the Pacman/Bradley fight. Tiger made the decision, and he's not going back.
