However here is a point un-made that I think is even more valid: he doesn’t really need more distance, but with an improvement to his impact conditions (and shall I say, swing model), he could get the same distance with less effort.
I wrote about Cameron Champ last year after seeing him in the ’17 U.S. Open, and he’s going to be playing on the PGA Tour next season – which means you may see him pretty soon with the wrap-around season!
Now, there’s no reason that a kid hitting it 350 yards carry distance would need any more distance, but find me one person, even among the longest hitters, who didn’t want more distance with their swings.
I’ve found some video of his swing, although the one I can’t find online is the rear view of his swing that showed a separating left heel on the back swing pivot.
It could just as well have been a one-off however because from what I see in other clips I’ve found online, he doesn’t seem to do it all the time, and that is the only concern I would have for a 22 year old who’s driving it 350 yards – that he be doing it with a mechanically-sound swing action.
