Dimeback is the name for a sixth defensive back in American football . However, he only plays in a certain defensive formation. The dimeback comes into play when the defense plays in the so-called dime formation . 6 defensive backs play in the dime formation. The dimeback has to replace a linebacker or a defensive lineman . This is the case when the opposing offense is set up with 4 or more wide receivers . Since the dimeback may have to keep up with 3 or more wide receivers, dimebacks need good maneuverability and speed. The dimeback position got its name because essentially two nickelbacks are on the field at the same time. And two nickels (5 ct) are equal to one dime (10 ct).
