Double coverage

This situation is often seen with standout wide receivers and running backs.

[1] It is extremely rare to have two defensive backs man-cover a single receiver.

[citation needed] Commentators who use the term "double-coverage" almost always mean a cornerback covering a wide receiver man-to-man, with a safety playing "over the top" (typically trying to stay in front of the wide receiver's route) for deep ball assistance.

Because zone coverage schemes often use six or seven defensive backs to cover the offense's five eligible receivers, one or two of these men can drop underneath a wide receiver's route while a safety or cornerback stays over the top.
