What hockey rules are really organizing
- Territory and entry: blue lines and the red line control when a team is onside, when a puck can be legally sent deep, and when play has to be brought back.
- Possession under pressure: the rules let players battle for the puck, but limit sticks, hands, holds, and body contact that create unfair advantage or danger.
- Stoppages and restarts: face-off locations, delayed whistles, and puck-out-of-play decisions matter because hockey resets play constantly.
- Scoring protection: goal-crease questions, goalkeeper contact, kicked or high-sticked pucks, and video review rules decide whether a goal counts.
