e/Nickel defense

Information
has gloss	eng: In American football, a nickel defense is a defensive alignment that uses five defensive backs. The fifth defensive back is called the nickelback. The defense has five defensive backs, and usually has four down linemen and two linebackers. A lineup of three down linemen and three linebackers is sometimes used, but this is often called a 3-3-5 defense instead of a Nickel defense. The four-linemen/two linebacker version of the Nickel is generally more popular because it affords the defense greater ability to stop an opponent's running game.
