This is not, I will say off the bat, any comparison between skill level or ability – people are always confusing swing technique versus the overall game or ability of a swinger and the two are not the same.
I have been looking at Cameron Champ’s down swing to impact however and have compared it to Brooks Koepka’sand this is the thing:
Here’s what I saw when I went looking for Brooks Koepka’s6 mph decrease in club head velocitybetween 18″ pre-impact to impact, and it should be plain to see for anyone who analyzes motion.
I’ve said before, been saying for years, actually, that when you squat into the address you will restrict hip turn, and when you restrict hip turn on the back swing, your hips will reach impact position before the upper body.
You’ll recall that during Tiger Woods’ last disastrous attempt to return to play on the PGA Tour, I made a tongue-in-cheek suggestion that he might look at another golfer’s swing (one Hideki Matsuyama) and perhaps ask him how to do it, if he insisted on a planted-heel golf swing.
As modern swings go, yesterday’s Waste Management winner Brooks Koepka(with his maiden PGA Tour win) has a swing that could be much, much worse.
If you’ve noticed that I don’t actually praise any modern swings, that’s because I feel they are mechanically-unsound, dangerous to the average person and simply not something I’m going to go out of my way to say nice things about.
