[O.B.Left]

K the geometry of the circle so far assumes a flat lie.

MJ re guys we love who wrote books and said they played the ball in the "same place" was t it vis a vis the left foot? If so and if they also narrowed their stance progressively consider how the left shoulder moves vis a vis the left foot. A wide stance versus a narrow stance. You could consider that if they did actually imploy a constant ball position vis a vis the left foot ( which is debatable) they had effectively moved the ball back of low point with their narrower stance. I'm writing on my iPhone my apologies if I'm not clear
