It is remarkably easy to become an accountant beside a junior sports field. One child comes off twice while another stays on. Ten minutes becomes fourteen. By the final whistle, the numbers feel like proof.
But a stopwatch records time, not the work being done inside it.
The same minutes can be a completely different job
Rugby union and rugby league: a middle forward can spend a stint carrying into contact, tackling, getting back onside and working through the middle again. A winger may stay out much longer and see the ball only a few times in that particular game.
Touch: middles repeatedly work through the centre in a fast game and are commonly rotated in short stints. The child coming off after five hard minutes may have done more running than someone who has stayed on twice as long.
AFL: on-ballers and rucks can rotate through demanding contests and stoppages, while key-position players may be managed differently. A wing in AFL can also be one of the biggest running roles on the ground—which is precisely why labels and minutes alone tell us very little.
Football (soccer): a central midfielder covering both attack and defence, a wide player making repeated high-speed runs and a centre-back holding shape are all doing different physical and tactical work. Ninety minutes is not one standard job divided evenly between eleven children.
Hockey: rolling substitutions can mean short, intense bursts for field players while a goalkeeper or another role stays on much longer. Coming off regularly is often part of how the game is played, not evidence that a child is less valued.
Basketball and netball: pace, defensive assignments, match-ups, fouls and court position all affect rotations. A basketball player working through screens and rebounds is not doing the same job as the player handling the ball, just as a netball centre covering most of the court cannot be compared minute-for-minute with a player restricted to one end.
Junior sport is not elite sport, and no coach gets every rotation right. These examples simply show why one child playing ten minutes and another playing twenty does not automatically mean they received the same opportunity to do the same work.
Sometimes the kid simply needs a break
In any sport, some children go hard for their first stint and are completely puffed by the end of it. If they stay out there and begin walking between efforts, the children around them often have to do more. Taking that player off may not be a punishment or a sign the coach does not rate them. It may simply mean the child needs a break and the team needs fresh legs.
Sometimes the whole mystery disappears when somebody explains the rotation to the child in plain language:
“A couple of minutes to get your breath and you will be back on.”
“You look puffed. Let's get you a break.”
“You are walking out there. As soon as you walk, you are off for a break.”
The last one can also be a bit of a “hey” moment. If a child is walking while the children around them are covering the extra work, it is fair to point that out. The break gives them a chance to recover, but it also makes the expectation clear: effort is not only personal when your teammates have to pick up what you leave behind.
That does not require a public dressing-down. It tells the child why they are coming off, what is expected when they are on and that the plan still includes sending them back out.
The bench matters too
There are also children sitting on the bench who have trained, turned up and equally deserve an opportunity to play. Every extra minute given to one child is a minute that cannot be given to another. Fair does not always mean identical minutes in every game, but every child should have a meaningful chance to contribute.
A familiar sideline version of this ends with a parent angrily challenging the team manager about their child's limited minutes. The child may have just worked hard for ten minutes, needed the rest and been perfectly comfortable with the rotation. The team manager may not even be the person deciding the substitutions.
Before the clipboard is blamed, there is a much simpler place to start: did anyone ask the child?
How did that stint feel? Were you exhausted? Did you want to go back on? Did you understand what the coach wanted from you?
That does not mean every concern about playing time is wrong. Favouritism can happen. Rotations can be confusing. Communication can be poor. It only means the stopwatch captures one part of the decision.
If the concern still matters after the emotion has settled, ask the coach one calm question: “Can you help me understand the rotations and what my child is working towards?” That will usually get further than a statistical case presented to the team manager in the car park.
The stopwatch can start a conversation. It should not be allowed to finish it.
