If the backswing was so important to making a golfer strike the ball well and produce a
repeatable golf swing then why do the golfers above have different styles at the top of their swing?
Is it really a fundamental to playing good golf?
The answer is NO- it isn't a fundamental ... however... the answer could also be a resounding YES..
Yes- because how we position ourselves at the top of the swing can set forth the entire motion
of the downswing movement and path to help us produce the desired result.
The important thing here to remember is that we HAVE to find the best top of the swing position for US.
The best spot that allows a steady flow of direction change from top to down and ultimately through and beyond to the finish.
