If you want to understand why people don’t like Bryson DeChambeau, all you have to do is watch him swing his club. His mechanics are deeply weird. He doesn’t bend his left arm. His club travels on a single plane, and all his irons are the same length. It looks like his swing shouldn’t even be legal, but it is. It looks like it shouldn’t work, but for some strange reason, it does. According to DeChambeau, his swing is the most physiologically advantageous one he could have. Golf is a game of physics and mechanical dynamics; golfers build their games based on the information available—that which can be observed, repeated, tested—and DeChambeau couldn’t care less what anyone thinks about how he swings his club.
