He's about average to below average as far as distance goes. His backswing with the bowed left wrist doesn't bother me because he gets it 'on plane' in the downswing every time. He's known as a good ballstriker who hits sizeable draws and his miss is an over-draw.
Watching his swing, he hangs back a bit thru impact, shoulders get really vertical, he 'swings out to the right' quite a bit and his rate of closure is very high. Pretty typical for a Tour player who hits that big of a draw.
But, with his level of quality ballstriking, it's easy to see that he has great timing and great hand-eye coordination. Somebody with 'pretty good' timing and hand-eye coordination, would likely be much less of a ballstriker IMO because that swing requires a lot of it.
If he was really long, like top 20 on the PGA Tour long, I'd consider that length for a swing that requires the timing and hand-eye coordination that he has to be a fair tradeoff. IF that was the case and I was him, I'd take solace that I have good hand-eye coordination and timing that most of the time I'll be okay and my top 20 power would bail me out a lot as well.
But, he has more or less average to mediocre power for a Tour player. I've seen the video of him on Trackman and he's basically understanding the elementary basics of D-Plane. I can't remember what his face and path numbers were, something like 1* face and 3* path. But he got the idea down and was practicing that diligently.
I think the pitfalls for a player like him is when he starts over-drawing it more and then starts missing shots to the right as well because he can't time the rate of closure as well as he once did. In the past, with the old ball flight laws...I think he would likely have mis-identified the problem. Now with Trackman, he can go and measure his numbers and if he's over-drawing, he'll know why and if he's blocking, he'll know why.
Still though, it wouldn't shock me if he has some issues in the future because he's still got to know how to fix issues biomechanically.
