What is a nickel in football?

In football, a nickel refers to a specific defensive formation used primarily to defend against the pass. The nickel defense features a total of five defensive backs on the field, with the traditional four defensive backs (cornerbacks and safeties) joined by a fifth defensive back, typically a nickelback or slot cornerback.

The nickel package is often used on passing downs when the offense is more likely to throw the ball. By bringing in an extra defensive back, teams can have more coverage options and better match up against multiple wide receivers or tight ends.

Nickelbacks are typically smaller and quicker than traditional linebackers or safeties, allowing them to cover slot receivers or tight ends effectively. They are often tasked with covering the slot receiver or providing additional support in coverage.

The use of nickel defenses has become more prevalent in modern football as passing offenses have evolved to become more prominent in the game. Teams often use nickel packages as a base defense, especially against teams with strong passing attacks.
