A defensive rebound occurs in basketball when a player retrieves the ball after a missed shot by the opposing team. This action is crucial because it prevents the other team from scoring and allows the defending team to gain possession of the ball. Players often position themselves strategically near the basket to increase their chances of grabbing the rebound. Successful defensive rebounding requires good timing, positioning, and physicality. Players must be aware of their opponents and anticipate where the ball will land after a missed shot. By securing defensive rebounds, teams can transition to offense and create scoring opportunities, making it a vital aspect of the game.
