Storytelling Over Swing Data: Inside Jerome Theunis's Coaching Philosophy

Jerome Theunis was a golf pro himself — a Challenge Tour player who represented Belgium in the World Cup — before he became one of the most sought-after (and quietly under-the-radar) coaches in the game. It started with his roommate on tour, a young Nico Colsaerts, who got sick of finding golf technique books in the bathroom and Sharpie diagrams on the hotel TV. "I think you're pure psycho," Nico told him. A few years later Colsaerts was in the Ryder Cup, and Jerome had found his calling.

Since then he's worked behind the scenes with players like Adrian Meronk and Thomas Detry. In this episode, Jerome unpacks the parts of coaching nobody puts in a swing manual: why he flies across the world to consult other coaches on his own players — and why Sean Foley called that "the biggest proof of trust" a coach can give; the four things that actually happen when you bring in outside expertise, and why it almost never backfires; the concept of "novelty salience," and the parking-lot debrief with a PGA Tour player that ran 50 minutes over because reframing one piece of technical data changed everything; why touching a tour player's technique "de-skills" them — and how Tiger Woods rebuilt his swing three times without ever disappearing from leaderboards; the grip Jerome refused to fix on a world number 11, because some flaws are load-bearing; Randy Smith's audacious fix for a player who "swings it beautiful" but couldn't close — shaping shots on Sunday, from a 50-yard slice down to dead straight; and why Jerome believes storytelling and emotional framing — not swing data — are the one thing AI won't be coaching any time soon.

Equal parts skill-acquisition deep dive and behind-the-curtain look at how tour-level trust actually gets built, this is a conversation for anyone who coaches, teaches, or just wants to understand why the best in the world can shoot 65 on a course that's "long, tight, and high rough" and make it look easy.
