zone dog
n.— «Instead of blitzing with man-to-man coverage behind it, LeBeau developed a way to pressure the quarterback by having a variety of players blitz from different angles to produce favorable matchups while backing it up with zone coverage. The technique, known as “fire zones” or “zone dogs,” now is used as a base pressure scheme by about a third of the teams in the league.» —“Steel Curtain now features frills” by Ken Berger Newsday (Long Island, N.Y.)
