The "defensive zone" in ice hockey refers to the area of the rink where a team's own goal is located. This zone extends from the goal line to the blue line, and it is crucial for a team to protect this area to prevent the opposing team from scoring. Players must work together to defend against attacks and regain possession of the puck. In the defensive zone, players often employ strategies such as forechecking and backchecking to disrupt the opponent's plays. Effective communication and positioning are essential, as players need to cover their assigned areas and support each other to maintain a strong defense.
