Steep vs. Shallow (the actual data revealed)
So should you be more steep or shallow on wedge shots? Today we have the data and coaching on WHAT to do from the guy who gathered all the data from top tour pros. Fascinating info and easy to understand examples. Check it out! Big thanks to the folks at TPT Golf who helped make this video with Jon happen!

I met with Kolby Tullier, an amazing trainer introduced to me about 5-6 years ago by Tony Ruggiero.
Kolby works with top golfers like Justin Thomas and Tommy Fleetwood, so I knew I was in good hands. His track record speaks for itself.
We started with a really cool assessment using a machine called the Oxefit. It measured my jumping power and tested my left and right side stability with weights.
Kolby dug deep into my mobility, stability, and overall strength.
From there, he identified exactly what I needed to work on. We went through a series of exercises that were challenging but eye-opening.
It all made sense—why I’ve plateaued in my speed gains. Kolby’s saying is, “You can’t shoot a cannon out of a canoe.” And wow, do I relate to that!
Here’s a clip from Instagram of me getting absolutely crushed by one of the exercises. 😂
The Floridian Golf Course and Meeting Claude Harmon III
The next day, we headed to the incredible Floridian Golf Course, home of Claude Harmon III.
Holy cow, this place was unreal! Hands down, one of the best facilities I’ve ever been to.
Claude Harmon III is one of the purest elite coaches I know. He’s been around the best players in the world and knows exactly how to make them better.
I was curious to see what he’d focus on with me.
His main message? We spend way too much time on technique and not enough on execution. That really hit home.
For example, we looked at my approach game.
My worst strokes-gained stat this year is from 100-150 yards—my Shotscope data doesn’t lie.
In his studio (with force plates and all the tech that we could dive into technique), he simply asked me to hit a 100-yard shot and then a 125-yard shot.
The problem? My distance control was terrible. I had no clue how far my shots were going, and I couldn’t control it.
Then he asked: “How often do you practice this?”
My answer? I don’t.
Claude’s advice was simple but powerful: put in the work. Focus on execution and build this skill. It's what the best players do every day.
Sure, technique is important, but even the best players in the world are always refining it.
Execution, though—that’s where real separation in talent happens.
While at the Floridian, I also bumped into Dr. Nico Darras of Golf Blueprint.
As someone who’s obsessed with motor learning, I’ve been following his work for a while. It was awesome to meet him in person!
Here's a great drill you should check out and play with a buddy next time you're at a putting green.
Huge thanks to Rapsodo for making this happen and supporting great content. Couldn't do it without them!
Till next time

I had Coach Will Robins back on the channel to tackle the question I hear most often: When you’re missing shots all over the place, does course management even matter?
