Start with the question
Every useful metric has a question behind it. Efficiency asks how often a team creates value. Explosiveness asks how much damage a successful play creates. Field position asks where possessions begin and how that changes scoring expectation.
If the question is unclear, the metric will feel like jargon. Start by translating the number into a football sentence, then decide whether that sentence helps explain the team, player, or game you are researching.
- Use the glossary when a term is unfamiliar.
- Read the units before comparing values.
- Avoid mixing metrics that answer different questions.
