One thing the pros do is they expect one kind of delivery, and let their reactions take over if it’s a different length. Ponting for instance, would be looking to get on the front foot (he said when in form, his front leg would be hovering just above the ground right at release!)..if short, he would then be able to jump off his front foot, and hit those devastating pull shots.
Steve Smith on the other hand, goes back, and stays back if short (no further back movement).
I think for us, this is too much. Simple stuff like staying in a balanced position, clear mind, and eye on the ball ALL THE WAY OUT OF THE BOWLER’S HAND will solve a lot of problems.
