Seeing What You Missed in Your Last Game

You remember last Saturday's game ?

Lucas kept missing his shots from the pivot. Kevin wasn't in the game. And on defense, you conceded too easily on the right side in the second half.

You're certain. You saw it. Did you?

What I Was Too Slow to See

I was coaching a youth team. We had an excellent scorer — the kind of player you naturally rely on in key moments. When he came in on the run, he scored. Game after game.

What I hadn't noticed — and what an opposing goalkeeper had perfectly identified — was that in those situations, he always shot to the same spot. No variation. Ever.

In the return fixture, that goalkeeper anticipated it. And again. Our player's performance collapsed. Under pressure, he was forcing his shots more and more. His confidence was eroding. And I was looking for explanations in his physical condition, in the context.

The reality was elsewhere. It was in a number I had never looked at.

What the Brain Does During a Game

A handball match is 60 minutes. Two teams on the court. Phases of play unfolding at full speed.

Nobody can see everything. Not even the most experienced coach.

So the brain does what it knows how to do: it chooses. It filters. It retains what confirms what it already believed.

Lucas has been missing his pivot shots for three weeks? The brain will notice them. It will also — without consciously deciding to — move on more quickly from the moments where Lucas got it right. Kevin looked disengaged? The gaze lands on him at the wrong moment, missing the sequences where he defended well.

This isn't a lack of professionalism. It's biology. Psychologists call it confirmation bias: we perceive, above all, what validates our existing beliefs.

And in sports coaching, this bias is everywhere.

The Untouchable Starter

Every coach has had a player like this at some point.

The one who has been starting all season because he "brings something". Because he's serious in training. Because last year, he came up big in three important games.

This player gets your trust. And that trust colors how you watch him in a game. His mistakes are easier to overlook. His efforts are more visible. His replacement, meanwhile, has to work twice as hard just to get noticed.

This isn't bad faith. It's human.

Objectifying Intuition, Not Erasing It

A coach's intuition is precious. It's built over years of experience, games lived, players observed. It would be a mistake to throw it away.

But intuition alone remains fragile. It can be right. It can also be the reflection of a bias, fatigue, or a particular emotional context.

Objectifying your intuitions doesn't mean replacing them. It means giving them facts to stand on. When you sense a player isn't in the game, being able to check — and sometimes discovering you were right, or that the reality is more nuanced than you thought. That's what turns a feeling into a solid decision.

The best coaches don't choose between instinct and facts. They use both.

A Game's Memory Is Always a Reconstruction

After the final whistle, you think you remember the game. In reality, you remember a handful of standout moments — the goals, the glaring mistakes, the emotional highlights — and your brain fills in the gaps with what it thinks it knows.

Two coaches who watched the same game can arrive at very different readings. Each is right, in their own memory. Neither is necessarily right about what actually happened.

That's why post-game debriefs can be complicated. Not because you lack competence. Because you're working from memories, not facts.

What It Changes, Concretely

Imagine coaching based not on what you think you saw, but on what actually happened.

Knowing, backed by numbers, that your team systematically loses the ball in the last five minutes of each half. That your defense on the right side isn't actually the problem — it's the defensive recovery after transitions. That Lucas, despite his two visible missed shots, has the best decision-to-efficiency ratio in your squad over the last six games.

This isn't about questioning your coaching instinct. It's about giving it solid foundations.

The best coaches don't rely solely on intuition built from experience. They know that intuition backed by data can be the difference that tips a game.

What if, for the next game, you also relied on data to bring a fresh perspective to your coaching?
