Regarding your quote in bold --- funny you should mention that. Based on the research I've done on golf lately, It's my impression that golfers are just recognizing that they actually don't see the club hit the ball because the force of the swing pulls their head up before impact. If they try to force their head to stay still through the swing, they are actually hurting the natural motion of the swing.
I wouldn't exactly compare it to a pool stroke because of the amount of movement involved and the intensity and force.
Fran,
As I said in a previous paragraph to that, I have never seen the implement hit any ball in any sport that I have played.
When I was teaching my oldest son to play golf there was a period where he started to stare at the ball with his hands & arms running across his body. I immediately explained the different outcomes & that he should not stare at the ball & to just let his head move when it wanted to do so. He never again stared at the ball. He hits the ball a mile & at sea level.
We have amazing minds & bodies & their connection is amazing too.
Sometimes what one does naturally is better than what is being taught until the 'science' truly understands & the teaching catches up to Mother Nature.
Now many times has a golf instructor said, 'keep your head down & look at the ball'?
If only I had a penny for every time.
Best,
Rick
