Coach Nana explains the "Cover 2 Man" defense, which is called separately from a standard Cover 2 zone. This defense features a "two high shell," meaning there are two safeties deep, who are free to cover their two halves of the field, acting as zone defenders. Below the safeties, the defense plays man coverage. The corners cover the outside receivers, while a linebacker or nickel back takes man coverage on other receivers. The Mike linebacker is typically assigned to man up with the running back. This scheme is a combination of zone and man coverage, similar to a Cover 1 but with two safeties.
