I posted something about Justin Thomas last March, a posting which I’ve since removed because of the grumpy tone (I was annoyed by the constant references to his being “pound for pound the longest driver on Tour”), but what I said about his long distance driving was mentioned by Brandel Chamblee in the post Round 3 “Live From” on Golf Channel.
Chamblee showed a graphic that illustrated how Thomas gets it done, and that has to do with impact conditions over raw club impact speed.
I have figured out a way to slow down the Mike Dunaway“stickman” swing gif. that I created years ago, and I found his positions to be illuminating.
There was a lot of discussion back in the Mike Austin days of the then-named DJ Watts Golfblog (later changed to Wax Golf when my swing theory diverged from the Mike Austin model in 2013), about their impact positions.
