Find the right question.
- Feet moving while the ball is held → traveling.
- A stopped dribble begins again → double dribble.
- Boundary play → inspect where the player or ball touched, and who touched last.
- A clock-related call → distinguish the game clock from the possession clock.
Use the whole possession.
A short clip may omit the catch, a defensive touch or the start of a count. Replay from before the disputed action. Note the rule set and then use the named section of the rulebook; a single slowed frame often cannot establish the sequence.
