Split-field Quarters is one of the most adaptive and flexible defenses a modern defensive coordinator can base out of. It molds and flexes to fit whatever an offense can throw at it. Offenses can only throw so many different numbers on either side of the center; up to four eligible receivers at the most, and Quarters can adapt to all of them. At the fundamental level, Quarters is based off a numbers system. The corners always relate to #1, the safeties and outside linebackers #2 (bracket), and the Mike always relates to #3. If a player can count to three he can play Quarters.
Utilizing split-field coverages takes the Quarters scheme one step further, creating even more adaptiveness and flexibility. Being able to tag a base defense with small coverage manipulations can transform a static Quarters look into a robber, invert (Sky), or trap coverage. Pressure doesn’t always have to be the answer either. The defensive coordinator doesn’t have to outsmart his coaching counterpart on the other side of the ball, just the young QB trying to run the offense.
Many coordinators want to focus on pressures as a way to combat offensive schemes. Don Brown, the Defensive Coordinator for the University of Michigan puts the words “Solve your problems with aggression,” in his install playbooks. Pressures are a great way to force the issue with offenses, but sometimes a defense needs to sit back and run its base. When sending five or more, a defense loses a man in coverage and can get overexposed or become deficient in a certain zone if the blitz coverage is not structured correctly. On early downs, many top DCs like to sit in their base defense. Being static can have its own set of issues too, but adding coverage tags to change leverage points and run fits can be just as “aggressive” as a pressure and force the QB to beat the defense and not the OC.
Aggression can mean a multitude of different things when it comes to defense. The obvious answer is to blitz, but defenses can manipulate the secondary to be aggressive in their pass distributions and against certain receiving threats. Every offense has counters built into their scheme to take advantage of a defense vacating zones or spinning to single-high. Not every problem can be fixed through blitzing. Sometimes you have to play your base. Below are three ways a split-field Quarters team can tweak their coverage while staying sound and aggressive in nature. You know, Cautious Aggression.
