cornerback

A cornerback is a defensive player in American football who primarily covers wide receivers to prevent them from catching passes. Positioned near the sidelines, they focus on disrupting the passing game through coverage, tackling, and sometimes blitzing the quarterback. Cornerbacks need agility, speed, and good instincts to anticipate play strategies and react quickly. Their role is crucial in pass defense, making it difficult for the offense to complete throws and gain yards through the air. They also support the run defense, tackling ball carriers when necessary.
