One of the biggest mistakes adults make in youth sport is assuming that all children of the same age are competing on a level playing field.
They’re not.
A 13-year-old boy can be standing across the net from another 13-year-old boy and, physically, they may be years apart in development.
One player may have already experienced significant growth, increased strength, greater speed and improved power. Another may still be waiting for those changes to arrive.
The same applies to girls, although the timing and impact can look different.
This creates an important challenge for players, parents and coaches.
The player winning today is not always the player who will be winning in three years.
In fact, many successful adult athletes were not the dominant juniors.
Why?
Because performance during puberty is often heavily influenced by biological development, not simply talent, skill or future potential.
A player who matures early may enjoy temporary advantages:
- Greater power
- Faster serves
- More physical presence
- Better ability to defend and recover
Meanwhile, later-maturing players can find themselves competing against opponents who are physically very different despite being the same age.
This is one reason why rankings and results should be interpreted carefully during adolescence.
As coaches, we need to look beyond the scoreboard.
We ask:
- Is the player improving?
- Are they developing technically?
- Are they becoming more resilient?
- Are they learning to compete?
- Are they building habits that will serve them long term?
These are often better indicators of future success than a tournament result at 12, 13 or 14 years old.
At The Game, we strongly support the principle that development should take priority over short-term outcomes.
Puberty does not affect all players equally, and comparing children purely on results can create unrealistic expectations and unnecessary pressure.
Some players will be physically ready earlier.
Some later.
Both pathways can lead to success.
The challenge for coaches and parents is having the patience to recognise the difference between current performance and future potential.
The goal is not to be the best 13-year-old.
The goal is to become the best player – and person – you can be over the long term.
