Great video as always. these should be collected and shown all at once. The best instructional pieces anywhere online. Dufner keeps his right elbow ahead of his hip line through out the backswing, seemingly making it really easy for him to follow the yellow brick road. What pitfalls if any are there in working on keeping the right elbow down and in front of the trail hip in the backswing? I played with a former college golfer that did the same thing and he could really hit it long for a smaller player. Is this something to work on or not for a player that swings way too much in to out ? Dufner has a great swing, really fun to watch someone with a compact swing hit the ball so well.
