because if you make one bad shot and someone capitalizes its basically game over in golf....it can come down to that putt that missed an inch left, or that 185 yard shot to the green that landed just off the fringe and not the green....he gets flustered.
but about his swing, it is insane, they did a sports science on him I believe and his hips turn so much more than anyone else in the history of golf. its pretty amazing to get that kind of rotation, I wonder if he will be able to keep that up later in his career or if it will cause physical problems.
and to the guy who said Tiger will be back...we can't deny it he is one of the best golfers of all time, but he is passed his prime, sure he might win another major maybe two....but he'll never be "back"
