Hi There,
You are correct in your assumption, if you could teach someone from chipping and then pitching they would get a better perspective of what is required in the full swing, especially at impact. It is also easier to achieve contact with the ball, thus gaining confidence.
The problem is no-one ever does because it's a macho thing, as soon as they see the long
clubs it all goes wrong, more brawn than brains I'm afraid.
You could make a much better player from scratch to scratch with patients.
Ian.
