Tiger couldn't keep playing with the Butch Harmon swing, because a big part of it was locking his left knee on the downswing, and the knee couldn't take it, leading to one of his surgeries.
I also liked Max's quote, as a Cal guy, but Scheffler is clearly the best right now. He's in Tiger territory as far as being able to shape his irons in both directions. The way Augusta National played this weekend reminded me of Shinnecock when Goosen won. On grees that hard, you need to be able to curve the approach against the slope of the green in order to stop it, and Scheffler can do that in both directions. It allowed him to go at spots, IMHO, that his pursuers couldn't. I don't think Homa would have caught Scottie regardless, but what happened to him at 12 was one of the worst breaks I've ever seen a player get on that hole, relative to the quality of the shot.
