One other interesting factor that I heard on Twitter and would open it up to this DG is that Bryson's short irons and wedges having 6 iron length shafts helps keep his swing speed up through thick rough. Logically that makes sense, but I have no idea if it had any impact on the final outcome.
Not sure. I would have thought that the longer shafts make his swing plane slightly flatter and that's not as good for coming out of the rough, but obviously it didn't slow him down much, so maybe the gain in speed outweighs the plane.
I do find it interesting that he is explaining a lot of this openly and apparently without much prompting from golf writers.
I'm a fan of genius, but I also believe genius is overrated [or over-written, anyway]. What the great players have in common, and what all winners have in common, is making the most of their abilities while not overstepping them. Bryson is more inclined to do that with numbers, and in truth, most of today's golfers are doing that much more than before because we live in the age of Trackman -- Bryson just takes it much farther because that's how his brain works. But, I mean, I have been pacing off my putts and applying percentages in my head for uphill or downhill since I was 15. You can try to make it sound like rocket science but it is mostly just arithmetic . . . it's just that most golfers are not even good at arithmetic.
