The Nadal factor: why pros play with margin
Professional margin doesn't subtract aggression: it makes it sustainable over an entire match.
When you watch the best play, you notice a constant pattern: they don't live on the edge of the net. Their clearance is high, stable and designed to sustain pressure without giving away errors.
That net clearance does not reduce aggression, it makes it sustainable. It lets them hit hard with a higher percentage and keep control of the exchange for longer.
NetLiner replicates that logic by raising the visual reference and forcing you to build more robust trajectories. With practice, you discover that playing with margin does not take away weapons, it gives you continuity and better moments to accelerate.
Takeaway: high-level tennis does not depend on permanent risk, but on intelligent aggression with margin.
