Dimeback

A "dimeback" is a term, primarily used in American football, to describe a defensive back who enters the game in situations where the defense employs six defensive backs. This defensive alignment is known as a "dime package," hence the term "dimeback." The dime package is most frequently used in obvious passing situations, typically third-and-long or when the offense is near the end zone and likely to pass.

The dimeback is usually smaller and quicker than a linebacker, emphasizing speed and coverage skills over size and tackling ability. Their primary role is to cover wide receivers and tight ends, disrupting passing plays and preventing completions. While the specific responsibilities of a dimeback can vary based on the defensive scheme and the opponent's offensive formation, they are generally tasked with deep coverage, zone coverage, or man-to-man coverage on a slot receiver or tight end.

The need for a dimeback stems from the evolving nature of offensive playcalling, which often utilizes multiple receiving threats to spread the field and exploit mismatches in coverage. By adding a sixth defensive back, the defense aims to match the offensive firepower and improve their chances of defending against the pass. The player selected to be a dimeback is often a cornerback, safety, or a hybrid player capable of excelling in pass coverage.
