I'd have to say the best point is that only Tiger knows the real reason, but all very good points! I was surprised to not see any hardcore Tiger defenders.

I think he was just unhappy about the way he finished, and even possibly a mental thing; to forget about the loss as soon as possible and not have the media remind him about it.

It was a team event, and rightfully so the focus should have been on the US victory, not the US victory and Tigers loss. Golf is a difficult sport to make about a team, and the media often doesnt help.
