Zone defence is a defensive strategy used in team sports, such as basketball and football, where players are assigned specific areas of the playing field or court rather than marking individual opponents. This approach allows teams to cover more space and protect key areas, making it harder for the opposing team to score. In zone defence, players work together to anticipate the movements of the ball and the opposing players. By focusing on their designated zones, defenders can quickly shift to help teammates when needed, creating a cohesive unit that can effectively counter offensive plays and limit scoring opportunities.
