Palmer's swing was -- and is -- far from pretty. His finish, a pretzel-like aftermath of released energy, will never win any prizes for aesthetics or grace. Having been taught by his father to hit the ball as far as he could.Palmer was probably one of the finest drivers ever. His hard swing and go-for-broke mentality was perfect for hitting the long ball. "He's a charger, in everything he does, and this reflects itself in his very fast, all-out swing," Gary Player once said.Despite taking a ferocious cut, Palmer was able to maintain control of his motion. A big reason was that he kept his head so steady throughout the swing. Jack Nicklaus, in studying the Palmer method, said, "You'll rarely see a golfer who turns better with less hint of sway either going back or coming through."And Palmer has always hit his woods much better than his irons. "There is no question that my iron play has been a real detriment to my golf," he once conceded. But what truly made Palmer great was his short game. Once again, Nicklaus provided his expert analysis, saying, "Arnie at his best was the greatest chipper and putter I've ever seen."Today, a look at Palmer's swing shows that it's not what it used to be.Peter Kostis sees several points Palmer could fix, beginning with the setup: "At address, Arnold is favoring his left side much more than he used to; he's not setting up behind the ball as much as he should. In addition, he is bent over the ball too much."When things go wrong, Kostis believes, a large part of the reason can be found in the address position. "The vast majority of the time, what you do in your swing is the result of what you've done with your setup," he says. Palmer's faulty setup leads to a poor turn that's restricted and a swing plane that's flatter than would be acceptable.Also, Palmer's head movement -- formerly an asset due to its stability -- is now a liability. "During the swing, Arnold's head starts left, moves right, then slides back left again and then falls back right again," Kostis explains. "If you're not steady, it's difficult to consistently hit the ball solidly."At the age of 66, Palmer's competitive career is drawing to a close. He already has bid tearful farewells to the U.S. Open and the British Open. But long after he has finished playing, Arnold Palmer will be remembered -- not for his swing, but for his contributions to golf.Palmer's swing was -- and is -- far from pretty.
