What it is

Match coverage, also called pattern matching, is a way of playing pass defense that starts like a zone but turns into man-to-man once a receiver enters a defender’s area.

In a game

Each defender first has a place to go and a set of rules. If a receiver runs into his area, he covers that receiver wherever he goes. If nobody enters his area, he keeps playing zone and reads the quarterback. Many modern coverages, including most Cover 3 and Quarters calls, are really match coverages.

More detail

Match coverage tries to get the best of both worlds. A pure zone has holes between the defenders, and pure man coverage can be beaten by a pick or a good route. By matching, the defense keeps its eyes on the quarterback as in a zone, but covers receivers closely as in man coverage. The rules tell each defender what to do against each route, for example “take the first man into the flat” or “man on #2 unless he runs out to the flat”.
