Roger Federer won almost 80% of his matches but only 54% of the points he played. Even one of the greatest players ever lost nearly every second point.
That should change how we think about mistakes in tennis.
Traditional coaching often treats consistency as error avoidance:
❌ Keep the ball in
❌ Repeat the correct technique
❌ Eliminate variability
❌ Stop and correct every mistake
But tennis is an adaptive problem-solving sport. Players must respond to changing information, pressure and an opponent actively trying to make them unsuccessful.
An error does not automatically indicate a technical problem. The opponent may have created a difficult situation, the decision may have been appropriate despite the outcome, or the mistake may provide useful information for the next action.
When coaches intervene after every missed ball, players can learn that mistakes are dangerous and that the coach must provide the solution. This can produce cautious players who protect practice performance instead of exploring what the game affords.
Federer’s message was not that errors do not matter. It was that one unsuccessful action should not control the next.
For coaches:
1️⃣ Stop judging every action as simply right or wrong
2️⃣ Give players time to adapt before intervening
3️⃣ Explore the intention behind the action
4️⃣ Distinguish poor decisions from unsuccessful outcomes
5️⃣ Design practices that include pressure, failure and recovery
6️⃣ Help players become less dependent on the previous point
Confidence is not believing you will never miss. It is trusting your ability to adapt after you do.
The goal is not to develop players who avoid failure, but players who remain functional while failure is happening.
Even Federer lost almost half of the points he played.
It really was only one point. Then the environment changed and another problem emerged. 🎾
How differently would you coach if you expected players to lose almost every second point?
