I agree.  He got so obsessed with the power game that he wasn't hitting any fairways.  It looks like he has lost some weiight too.  I know that Hank Haney hated the fact that Tiger was bulking up as it took away some flexibilty and feel.  Butch Harmon has commented on this as well.  He looks a lot more comfortable with his swing and his short game seems to be back...if he can putt well he will win a few more times this year.
