What Mr Hall would like us to visualize is the putter is two halves it has the upper half and it has the lower half. What he wants you to do is feel like the ball is impacted by the upper half of the putter 1st as opposed to the lower half. What most amateurs do is they use their wrist and when you use your wrist the bottom part of the putter impacts the golf ball when this happens the clubface lays back on the ball is launched into the air. If you hit the golf ball with the top half of the putter the putter shaft tends to lean forward and the ball has to come off in more of a rolling type of fashion.

Now this is not reality this is more of a thought and even more of a feel so the feeling for you is to make sure that if there's a race between the upper half and the lower half the putter the upper half always wins. Now one caution you want to make sure that you take this literally and don't overcook it if you lean the putter shaft too forward and you drive the putter into the golf ball you're going to have the ball start to bounce. So once again just gently talk your wrist forward and let the other have the putter leave the race to the ball if you do so hopefully it will make a lot of putts that's what I'm talking about.
