what's good for the goose is not good for the tiger

Well, it was all set up for Tiger. With the 54-hole lead at the Tour championship, and not having lost a 54-hole lead in 4 years, today should have been money for Tiger. Instead, Retief Goosen shot a lights-out 64 to come from 4 shots behind to win the tournament. Tiger struggled the back nine and indeed most of the day to shoot a 72. There were many positive signs this week of Tiger regaining his winning form, but today was a big disappointment, as even Tiger admitted.

If you haven't heard, Tiger's using a new 460cc Nike driver and was No. 1 in driving distance this week.
But he was last in driving accuracy. ESPN has a good article about the bad year for Tiger.
