When we think of past Open Champions PGA Tour player Ben Curtis is often forgotten about. He was no doubt a very surprising winner of the 2003 Open Championship. Major winners Vijah Singh, Tiger Woods, and Davis Love III were all right behind him. Curtis had a tough time adjusting to being an Open champion, but he has been playing better over the last couple of years.
Ben Curtis has a back swing that is all his own. It is not as crazy as Furyk's, but it is a little choppy. He picks the club up very quickly with his hands, and he has a little extra movement at the top of his backswing. I would certainly prefer not to see those things in a golf swing. There is already enough movement in a golf swing, and like most sports, the game becomes simpler when you eliminate unnecessary movements. The less extra movement in your swing means the easier it is to be consistent and have great contact.
When watching the video I want you to notice to how tall he stands at his address position. He is not hunched over. It is not that you have to be tall to hit the ball far, but you do want to stand tall into the golf ball.
The key thing to learn from Curtis is that he trusts his motion. He trusts his swing and knows his ball flight. It is that trust, which has lead to confidence, which has him playing better and better. If you look at the end of his swing..does his finish position really look any different that most other players. No. This means that if you can develop an effective repeatable motion that you can trust, then go with it.
Golf is not like figure skating. There are no judges evaluating and scoring your game. Golf is about getting a little ball into a hole. If you can get the ball in the hole, it does not matter how you do it. My dad always said "there is no room on the scorecard for a description."
