Kenny Perry's swing with the driver is as unorthodox as it is effective. He keeps his right heel on the ground longer into the follow-through than anybody on tour, a move that you see a lot with the short irons but is less common with the longer clubs. The upside for Perry is that it helps him stay balanced and "grounded." It also helps him achieve his natural ball flight (a hard draw) because he hangs back on his right side a bit and rotates the clubface to a slightly closed position with his hands. Perry's move is becoming sort of a trend on tour, though other guys aren't taking it to the extreme he does. The idea is to keep the lower body quiet through impact.
I don't recommend this move for the average player, because the faster momentum with the driver can put a lot of stress on your lower back.
