When I began my career in golf, it was the Big Three who were the prominent golfers on television. Arnold Palmer, Jack Nicklaus and Gary Player. Their golf swings all looked different. In my years in training as a golf professional we were required to examine and be familiar with the progression and changes of the golf swing and equipment. This began with the olden day era of Harry Vardon then moved forward to the players of the day. Forty-five years on the experts have still not settled on a PERFECT SWING TECHNIQUE. I don’t think the average Jo golfer needs to know all about this, as it will not help his game next weekend. However for students of golf or advanced golfers it makes very interesting background knowledge.
