The answer is…..only on the way down! Having a picture perfect back swing only makes it easier to accomplish that very necessary picture perfect down swing. However, this is only in theory.
Too many golfers spend years working on trying to make all the perfect swing motions shown in golf magazines and on TV, only to waste valuable years that you cold have been spent enjoying the game. There are no points for technique here. This is NOT the Olympics!
What about Lee Trevino, Jim Furyk, Tony Lema, John Daly, and yes even Sam Snead did NOT have a perfect back swing. I remember seeing Sam for the first time in Miami at the Eastern Airlines Open and thinking, holy cow, he’s over the top on the down swing! Not really, but I was only 14 then and learning.
Here’s an analysis of a very successful player, Jay Haas. His back swing is certainly less than perfect. It might be that one needs to have better tempo and balance to repeat a back swing that is not perfectly on the swing plane. I have always said that great balance, rhythm and tempo will overcome swing faults.
Take a look at this analysis and see what you think.
