Trust me it's not a dependable swing, not a go-to swing, like he had before. Way too controlled, contrived, forced, and unnatural...his body is fighting it. He needs to get back-to-basics; most notably his alignment, natural weight transfer, better footwork, extension and release. I've been studying the golf swing for over 25 years, and his since he won the U.S. Amateur three times.
