How the call is made
- Decide whether the action is legal contact or a foul.
- If it is a foul, judge the level: careless, reckless, or excessive force.
- If the player is reckless, a yellow card is usually needed. If the force is excessive or the challenge endangers safety, it is usually red.
- Then ask whether the foul stopped a promising attack or denied an obvious goal-scoring opportunity.
- Combine the foul and sanction into the final decision.
