The biggest myth of the swing-your-swing movement, which is noble in its cause, is that you should leave it untouched.
Scottie Scheffler has one of the most unique swings in golf—and one of the most coached. The legendary instructor Randy Smith has been his coach since childhood, and together they've spent years tweaking and refining his move. The truth is that when it comes to swinging your best swing isn't resisting all change. It's knowing the right things to change to unlock your true potential.
Last year, writer Matt Rudy paired with Smith to tell the story of how Scottie got so good (you can read that fantastic article right here). In that article were four different videos of Scheffler through the years that few have ever seen before. Let's take a quick look at each of them.
Young Scottie
Before Scheffler hit his growth spurt, his swing had a classic junior golfer move: A club that was too long and heavy for him pulling him into a long backswing.
In the article, Smith said he and Scheffler routinely tweaked Scottie's grip over the years. Here, his left hand thumb is running more down the middle of the grip (weaker) and his right hand is more on the side of the club (stronger).
Junior Golf
Scottie chased distance any way he could get it as a junior golfer, and did it by hitting right-to-left draws, as he explained in Golf Digest's The Grid. This caused his takeaway to get more inside and his swing to move more in-to-out than it is now.
Notice, too, how Scheffler's head drifted continuously towards the target on the backswing, downswing and follow through. That's something that's about to change, too...
College Golf
Scheffler didn't just get taller—he also got stronger. This helped his body get a little more structure to his dynamic, athletic movement. His head stays slightly more behind the ball at impact. He also maintains some flex in his right knee as he makes his big turn on the backswing—it's what helps him drive his lower body so aggressively towards the target on the downswing.
Pro Golf
Scottie is your prototypical professional athlete now: Tall and strong. His left hand grip has gotten stronger and his right hand grip has gotten weaker, which Smith writes matches his body movements better. His backswing has gotten shorter since his junior golf days, too. But he has the same sense of clubface awareness that helps him hit elite golf shots.
