Most golfers look at Jon Rahm swing and cannot work out how he generates so much speed. If your top and bottom half are in the correct order and you are coiling, you can swing the shaft faster. Players that talk about dropping the arms and swinging the arms from the top are coilers. If you slide laterally with your lower half going back your arms have to wait coming down. In this new Tour Lesson Gary compares a couple of major winning swings, and explains the different arm directions and the way they generate speed.
