Dimeback

In American football, a dimeback is a cornerback or safety who serves as the sixth defensive back (fourth cornerback, third safety; and in some rare cases, a fourth safety) on defense. The third cornerback or safety on defense is known as a nickelback. The dimeback position is essentially relegated to backup cornerbacks and safeties who do not play starting cornerback or safety positions. Dimebacks are usually fast players because they must be able to keep up on passing plays with 3+ wide receivers.

Dimebacks are brought into the game when the defense uses a "Dime" formation, which uses six defensive backs rather than four or five. Usually, a dimeback replaces a linebacker in order to gain better pass defense, although some teams may substitute the extra defensive back for a defensive lineman in their dime formation.

American Football

Game play in American football consists of a series of downs, individual plays of short duration, outside of which the ball is dead or not in play. These can be plays from scrimmage – passes, runs, punts, or field goal attempts (from either a place kick or a drop kick) – or free kicks such as kickoffs and fair catch kicks. Substitutions can be made between downs, which allows for a great deal of specialization as coaches choose the players best suited for each particular situation. During a play, each team should have no more than 11 players on the field, and each of them has specific tasks assigned for that specific play.
