Defensive drills are practice exercises designed to improve a player's ability to defend against opponents in sports like basketball, soccer, or football. These drills focus on skills such as positioning, footwork, and reaction time, helping athletes learn how to anticipate and counter the movements of their opponents effectively. Typically, defensive drills involve scenarios where players must react to offensive plays, maintain proper spacing, and communicate with teammates. Coaches often use these drills to reinforce defensive strategies and build team cohesion, ensuring that players are well-prepared for competitive situations.
