Keep One. Change One. I had an interesting conversation with a player recently during practice. We were working on changing a technical skill. Rather than giving him a list of corrections, I asked him to focus on two things as the drill progressed: Keep one thing. Change one thing. Keep one element of the skill that was already working. Change one element that we were trying to improve. That's it. As the drill progressed, we could evaluate the adjustment, reinforce what was working, and gradually introduce another change. It got me thinking about how we coach skill development. As coaches, we often see five things we'd like an athlete to correct. And because we see them, we want to fix them. But does giving an athlete five corrections actually accelerate learning? Or does it create five competing thoughts when they're trying to perform a skill that needs to become instinctive? There's a difference between understanding a correction and being able to execute it. And there's an even bigger difference between executing it in a controlled drill and trusting it under pressure. I think our job as coaches is to make the next adjustment clear enough that the athlete can explore it, feel the difference, and eventually own it. Not every rep needs another correction. Sometimes the athlete just needs another opportunity to figure it out. Keep one. Change one. Repeat. I'm curious how other coaches approach this. When you're helping an athlete change an established skill, how much do you introduce at once? And how do you know when they're ready for the next adjustment?
