This is a great drill to feel the sequencing of the lower body. By starting the swing from the 9 o'clock position you will have very little shoulder load, so the only way that you will create speed and solid contact is to use your lower body to initiate the swing. Also, this drill can be used to feel load on the downswing if you try to keep your the club at the 9 o'clock position as long as you can before you hit the ball.
