The one with a different answer is probably the best player. His or her answer will have nothing to do with their swing. That player already knows that improving one's swing DOES NOT guarantee an improvement in their golf game.
Most golfers mistakenly believe the golf swing is the most important thing in golf.
Their belief is understandable. Sadly many of today's teaching professionals continue to promote that belief. I confess, I too was guilty of it. The truth is you only use a full swing on about one third of your golf shots. Think about this, in order to shoot par you are allowed 36 putts which is exactly half of your shots on a par 72 course.
