If you stood behind the fence at one of my Sarasota junior sessions and counted how often I say something during a rally, you might think I was barely working. A player nets three balls in a row and I stay quiet. She finally finds the right height over the net, and only then do I say a word. Parents sometimes ask why I let the misses go. The honest answer is that after thirty years of coaching, I’ve learned that Michael Boothman talking is not the same thing as a player learning.
There’s a name for what I’m doing. Motor-learning researchers call it bandwidth feedback — you set a tolerance around “good enough,” and you only step in when the error crosses that line. Small misses inside the band get no comment. Big ones outside it get a short, specific cue. It sounds like laziness. It’s actually one of the most reliable ways to build a stroke that holds up under pressure.
What happens when a coach corrects everything
Picture the opposite. A player hits a ball, and before it even bounces the coach is talking: “bend your knees, watch the ball, follow through, get sideways.” Every single repetition comes wrapped in instruction. It feels thorough. It feels like coaching. And it produces a very specific kind of player — one who hits beautifully as long as the coach is feeding the next correction, and falls apart the moment they walk onto a match court alone.
The reason is simple. When a player leans on constant external feedback, they stop building their own internal sense of what a good ball feels like. The coach becomes a crutch. Take the crutch away — which is exactly what a match does — and the stroke wobbles. Researchers studying how often to give feedback have found again and again that less frequent feedback often produces worse practice-day results and better retention weeks later. The player who struggled a bit in practice owns the skill. The player who was propped up every rep only rented it.
The band lets a kid figure it out
This ties directly to one of my Six Pillars: Confidence Is Built, Not Given. Confidence doesn’t come from a coach saying “great job” after every ball. It comes from evidence — a player watching their own numbers climb because they solved a problem themselves. Bandwidth feedback protects that process. When I let a slightly-low ball go without comment, I’m giving the player the chance to feel it, adjust on the next one, and register the fix as theirs.
Here’s what it looks like on a Sarasota court. A twelve-year-old is working on net clearance in a live cross-court rally. My tolerance band is: clear the net by roughly a racquet-length and land past the service line. A ball that sails a foot high but lands deep? Inside the band. Silence. A ball that clips the tape and dies short? Outside the band. Now I give one cue — “up and over” — and nothing else. Nine times out of ten, the next three balls climb back into the band on their own. She corrected it. Not me.
Notice what the band also does: it keeps me honest about live ball. This only works inside real rallies, not off a basket feed, because the whole point is that the player is reading a genuine incoming ball and solving a real problem. Feeding perfect balls and correcting each one is the exact trap bandwidth feedback is designed to avoid.
How to set the band honestly
The band only works if it’s honest. Set it too wide and you’re just ignoring real problems — a player grooving a broken swing while you nod along. Set it too narrow and you’re back to correcting every ball. So I anchor the band to the one thing that actually decides points: where the ball lands, not how the swing looks. Height, depth, direction into a target — those are outcomes I can see and, more importantly, ones the player can feel. I mostly leave the mechanics alone unless a genuinely broken pattern is producing the misses. A useful test for parents at home: if you can’t describe the “good enough” zone in one sentence a ten-year-old would understand, the band is too vague to coach from. “Over the net by a racquet and past the service line” works. “Better topspin” does not. Clear bands make quiet coaching possible, because both of us already know what counts.
Why the silence is the hard part
I’ll be honest — staying quiet is the hardest coaching skill I know, and I still fight the urge. When you can see the fix, every instinct says to hand it over. But handing it over robs the player of the small, useful struggle that makes the fix stick. The discipline is in choosing when the error is big enough to earn a word, and trusting the player to handle everything inside the band.
For parents watching from the fence, this reframes what “good coaching” looks like. A coach who narrates every ball is not necessarily working harder or caring more. Sometimes the coach saying less is the one giving your child more — more ownership, more problem-solving, more of the durable confidence that shows up on a match court when nobody is there to correct anything. If you want to see how this fits into the wider system, our coaching approach page lays out how the pillars connect on court.
The band isn’t about ignoring mistakes. It’s about respecting them. A miss inside the band is a player learning. My job is to know the difference — and, most of the time, to keep my mouth shut long enough to let it happen.
