Dime Defense is a strategic approach used in American football, primarily in the secondary, to defend against passing plays. It typically involves six defensive backs on the field, allowing for better coverage against multiple receivers. This formation is particularly effective in situations where the offense is expected to pass, such as during long-yardage plays. The name "Dime" comes from the term "dime package," which refers to the sixth defensive back being added to the lineup. This strategy aims to enhance pass coverage while still maintaining some level of run defense, making it a versatile option for defensive coordinators.
