Q: I have a one plane swing and I'm following your advice, but I'm blocking the ball right. What would you suspect is the cause?
A: You are too far underneath the swing in the downswing/impact area and not enough on the inner circle. Find my drills for being too much from the inside and underneath or on the outer circle. You need to turn your entire body, upper and lower body aggressively in the downswing and lower your right hand to a spot as near your right pants pocket that you can. From there just keep turning and let your right hand go around to the left close to your pants and do not let it swing outward towards the ball/target line. This will get you in-to-in on the inner circle...
