Rugby Union

Lomu's breakthroughs become more informative when viewed alongside the passing and positioning that brought him the ball.

Timing, legal body position and repeated involvement explain the less conspicuous work around rugby's contact area.

The famous 2003 final drop goal also provides a route into understanding organisation and the preparation of a scoring position.

Identify rugby union's framework before applying assumptions from American football or rugby league.

Different scoring methods create different choices about territory, possession and the value of the next phase.

Binding, stability and the release of the ball make a scrum more than a contest over who pushes hardest.

Throwing, jumping and support turn a touchline restart into both an aerial contest and a tactical platform.

The ball's location and whether it remains carried by a standing player help distinguish rugby union's contact phases.

Landing area, pursuit and the defensive shape afterwards determine whether a kick creates a useful advantage.

Reduced numbers and shorter matches amplify the importance of coverage, possession and immediate support.
