Your child had ten touches last week and three this week. Same kid. Same club. Different oval.

If you are trying to figure out what went wrong, you’re not alone. But here’s the thing: nothing went wrong. Performance variation in junior players is so normal it has its own name in sports science circles — and if you know what to expect, it stops feeling like a warning sign and starts feeling like just… footy.

Why does a junior AFL player’s performance change so much week to week?

Because they’re kids, and kids aren’t machines.

Even elite adult athletes have significant game-to-game variation — that’s why coaches look at rolling averages, not single-game stats. For a ten-year-old playing under-13’s for the Kenmore Bears on a Sunday morning, the variables are multiplied about eight times over.

Opposition quality matters enormously. A game against a bottom-four side looks completely different to one against a well-drilled team who just came back from a carnival. Your child didn’t get worse between games. They just met better pressure.

The weather plays a bigger role than people think. A cold, wet oval with a slippery ball changes disposal numbers, marking contests, and how freely the game flows — for everyone. If it was the kind of morning where you were huddled in a jacket wondering why you’re doing this, their stats were probably down across the board regardless of who was playing.

Fatigue is invisible until it isn’t. Junior players don’t always know how to tell you they’re running on empty. A big school week, broken sleep, a busy weekend before — it all lands somewhere. Usually in the second half, when their legs stop doing what their brain asks. This is always a good reason to prioritise a quality sleep the night before a game.

Field position changes everything. If your child played a different position this week — even within the same general zone — their touch count, disposal type, and involvement can look completely different. That’s not regression. That’s a different role.

What a single game’s stats actually tell you

Not much, if you’re honest about it.

A single game is a sample size of one. In a sport where a kid might get three or four genuine opportunities to touch the ball in a quarter — depending on where play goes — a difference of six touches between games is the margin of two unlucky bounces and a forward pocket who beat them to a contest.

What a single bad game can tell you: whether your child finished strong or faded (which might be a fitness or fatigue signal), whether they were engaged and working off the ball, and how they handled adversity when it wasn’t going their way. A development coach watching that same game would probably focus on those things and barely glance at the score or the touch count.

Why season-long patterns are the actual signal

If you’ve been tracking stats across a few games, here’s what to look at.

Are they getting more involved in contested moments over time — not necessarily winning them, but competing? Are their decisions improving, even when the outcome didn’t go their way? Is their pressure — chasing the ball, getting to contests, backing up — trending in the right direction?

These things don’t show up clearly in a single game. They show up across eight, ten, twelve games. A child who had four bad games in a row and then three steady ones hasn’t regressed and recovered — they’ve been on a normal development curve. The bad games were part of the pattern, not exceptions to it.

The car ride home problem

There’s a specific kind of anxiety that lives in the ten minutes after the siren, when you’re trying to read your kid’s body language from across the oval and figure out whether to say something or stay quiet.

Most of that anxiety is about a single game. And most of it resolves itself if you give it a week.

The conversation worth having isn’t “what happened today?” It’s the slower one — maybe mid-week, maybe at dinner, maybe just occasionally — about what they’re enjoying, what they’re finding hard, and what they want to work on. That’s the conversation that maps to real development. The game-by-game debrief mostly just creates pressure. What they are mainly wanting after a game is simple support.

A stat sheet from one game is a snapshot. What you’re actually trying to build — for them, not for you — is a picture of a season. And that picture takes time.

One thing worth actually tracking

If you are going to record anything, record enough of it to see a trend.

Three or four games of data starts to mean something. Ten games is genuinely useful. One game, no matter how dramatic it felt on the day, is noise.

Apps like ScorX let you log touches, disposals, goal assists, and pressure acts game by game — not to obsess over any individual number, but so that at the end of the season your child can look back and see, clearly, that they improved. Not a feeling. Actual numbers. Kids who can see their own improvement are more likely to keep playing — which, at this age, is the whole point.

Frequently Asked Questions

Is it normal for a junior AFL player to have a big game one week and struggle the next?

Yes, completely. Even in the same team, against similar opposition, a junior player’s stats can vary significantly from week to week due to fatigue, field position, opposition pressure, and how the game flows. Single-game variation tells you almost nothing about development. Season trends are what matter.

What causes performance variation in junior AFL players?

The main factors are opposition quality, weather conditions, fatigue (from school, sleep, and activity outside sport), field position changes, and natural day-to-day variation in energy and focus. These are all normal, and all temporary.

Should I talk to the coach if my child has a bad game?

A one-off bad game probably doesn’t need a conversation. If you’re seeing a sustained drop in engagement or confidence over three or four weeks, then yes — but focus the conversation on how your child is feeling rather than the stats. Coaches notice a lot more than touch counts.

What stats should I track for junior AFL development?

Effort-based stats are more useful than outcome-based ones at junior level. Things like pressure acts (chasing and tackling attempts), involvement in contested moments, and decision-making under pressure give a better picture of development than goals or touch count alone.

How many games of data do I need before the numbers mean something?

Three to four games will start to show a pattern. Ten games is where you can start making reasonable conclusions about trends. One or two games — even if they’re very good or very bad — should be treated as data points, not verdicts.
