The secondary is responsible for:
- preventing a score from the offense
- Countering receivers on the offense

A defensive back is another name for a player in the secondary. Defensive backs can refer to cornerbacks, linebackers, free safeties, or strong safeties.
The cornerback is a defensive back who protects against the pass and counters wide receivers on the offense. Cornerbacks must follow receivers that run routes on the field to prevent a pass from being caught.
The linebacker is a versatile defensive back that can protect against the pass, blitz the quarterback, or tackle the ball carrier depending on the play.
