My teaching philosophy is pretty simple. I don't care what your swing looks like. It's all about impact! The golf ball doesn't care if you're across the line at the top. The golf ball doesn't care that your left foot came off the ground as you reach the top of your backswing. The golf ball doesn't care that your left wrist is slightly cupped. All you need to do is deliver the club face, with some speed, on a good angle. I have a motto. "Fix the face and everything else will fall into place." So many good (and bad) things in the golf swing are a byproduct of club face control.
