Why are folks "down" on Haney? Tiger perfected his swing plane under Haney. Everyone got on the "laid off" bandwagon criticism. But laid off is when the clubshaft is under the left arm plane at the top. Tiger was pretty much spot-on, perhaps just a HAIR under plane at the top, much like Hogan and Sorenstam, two of the straightest pure ball-strikers ever. Remember, Tiger's been the best iron player in the game for a long time. His problems have ONLY been with the driver. Yet folks act as if his swing needs a complete overhaul.
Tiger has picked up some yards with the driver recently. But its due to finally ditching the highest-spinning, shortest-hitting ball in golf. He was giving up 15 yards, easy, with that "marshmallow" he insisted on playing...until now. Tiger's always the last one to take advantage of technology.
If I could make on change to Tiger right now, it would be to extend the arms away from the body slightly more at address, so when he goes "down" after the ball, he STAYS down, instead of "backing up" out of the way just prior to impact. Virtually every great driver of the ball has the grip cap several inches "out" from under the shoulder sockets. Tiger USED to be there. Not anymore.
