The Zone Blitz Explained

The zone blitz sends a surprise rusher and drops a lineman into coverage. See how the call works, why it was invented, and how offenses try to punish it.

Few moments in football are as strange to watch as a 280-pound defensive end turning away from the quarterback and backpedaling into the flat to cover a running back. The first time many fans see it, they assume something went wrong. In fact, the defensive end is doing exactly what he was told. His coach sent a linebacker, a safety or a nickel defender at the quarterback from a direction nobody expected, and asked the lineman to step out of the rush and take a coverage job instead.

That is the zone blitz: a pressure call that rushes five (or sometimes six) defenders, including at least one who normally plays in coverage, and drops one or more linemen back to cover short zones. It combines two ideas that used to be opposites. A blitz brings extra pressure; a zone shell keeps defenders facing the quarterback with eyes on the ball. The zone blitz tries to have both.

This article explains how the call is built, why coaches like it, what the dropped lineman is asked to do, and how offenses attack it.

The problem it was designed to solve

Traditional blitzes had a flaw. When a defense sent an extra rusher from a linebacker or safety spot, it took a coverage defender out of the play. Offenses learned to throw immediately to the receiver the blitzer had left uncovered, often a short route behind the line of rushers. This is the hot route described in blitz types and pressure packages: a quarterback who sees the blitz can find the open area in a second.

Defensive coaches wanted pressure without leaving that receiver alone. The zone blitz does this by arranging for a different defender to occupy the vacated space. If the linebacker who normally covers the flat rushes the quarterback, the defensive end covers the flat in his place. The quarterback who throws hot into the flat finds a defender already standing there.

Credit for developing and spreading the idea is shared among several coaches and is sometimes argued over. Dick LeBeau is the name most often attached to it, from his years as a defensive coordinator with the Cincinnati Bengals and later the Pittsburgh Steelers, and other coaches built similar calls around the same time. When you read about its origins, expect different sources to emphasize different people.

The basic structure

The most common zone blitz is called a fire zone. In its standard form it rushes five defenders and drops six into coverage, arranged as three defenders deep and three underneath. That coverage shell is the same as the one used in Cover 3: three deep defenders (two cornerbacks and a safety) divide the deep field in thirds, and three players cover short zones.

What makes it a zone blitz rather than just a Cover 3 with a blitz is who plays where. In a normal defense, the underneath zones belong to linebackers. In a fire zone, one of those underneath players is a lineman, and one of the rushers is a linebacker or defensive back.

A simple example, described in plain terms: Imagine a team in a 3-4 alignment with three linemen, four linebackers, two cornerbacks and two safeties. At the snap, the two outside linebackers rush from the edges. The nose tackle and one defensive end also rush. A third lineman, the other defensive end, steps back and drops into the flat. An inside linebacker also rushes through a gap. The other inside linebacker drops into the middle hook zone, the two cornerbacks and one safety play three deep, the second safety covers the opposite flat, and the dropped end covers the flat on his own side. That is five rushers (two outside linebackers, nose tackle, one end and one inside linebacker) and six in coverage.

If the offense expected the end to rush, it did not account for the player who covers the flat. If it expected the inside linebacker to cover, it may be surprised when he rushes.

Who drops and why

The dropped lineman is almost always a defensive end, and sometimes a defensive tackle in a 4-3 front. The coaches choose the player who is in the best position and who has the best athletic ability for the job.

The dropped lineman usually has one of three responsibilities:

1. The flat. The area along the sideline near the line of scrimmage, where a running back or tight end will go on a quick route.
2. The hook or curl zone. The area a few yards deep, inside the hash marks, where a receiver stops or turns back.
3. The "hot" receiver. Whichever player the quarterback will throw to after seeing the blitz. The lineman has been placed to take away the likely throw.

The lineman is not expected to cover deep or to run with a speed receiver. His job is to get to the right spot at the right time, with his eyes on the quarterback, and put himself between the ball and the target. Coaches look for linemen with long arms, since a long arm can deflect a pass that a lineman could not otherwise reach, and they often practice the drop as a skill with the linebackers.

The pieces and their jobs

The rushers

The rushers must create enough disruption that the quarterback cannot sit and scan the field. A common way to do this is to send a blitzer from a position that surprises the blockers, often from the side the offense expects to be quiet. The linemen who still rush have to do their normal jobs.

The coverage defenders

The six coverage defenders play a zone shell, usually a version of Cover 3. The cornerbacks cover the deep outside thirds. A safety takes the deep middle third. A linebacker takes the middle hook, and the remaining defenders (including the dropped lineman) take the flats or curl zones. Because they are in zone, they are looking at the quarterback rather than chasing a receiver, and they can react to the throw.

The communication

Zone blitzes require communication. The defensive line and linebackers need to know exactly who is rushing and who is dropping. A single mistake can leave a gap in the coverage or a receiver without a defender. This is part of why the call is mostly seen in defenses with experienced players and a lot of practice time together.

What it does to the offense

The zone blitz targets the process by which blockers and quarterbacks identify and answer a blitz.

• Blockers assign themselves to the wrong rusher. A guard or tackle who expected a lineman to rush finds that lineman has dropped, and a blitzing linebacker is coming from a different gap. For a moment the blocker is blocking air, or a rusher is unblocked.
• The hot read is taken away. A quarterback who sees a linebacker blitz and prepares to throw to the vacated area finds a lineman there.
• The protection count is wrong. Offenses count rushers to assign blockers. A zone blitz has the same number of rushers as a five-man pressure, but from different players than the count assumed.
• The quarterback hesitates. When a quarterback is unsure where the pressure will come from, he can hold the ball a fraction too long.

The effect is not only a sack. Often the benefit is a rushed throw, a throw into coverage, or an interception from a lineman who has dropped into the quarterback's passing lane. Defensive coaches are glad to see a lineman intercept a pass, because it shows the call did what it was meant to do.

How offenses attack it

Offensive coordinators have studied the zone blitz for as long as it has existed. The standard answers are worth knowing.

Throw quickly behind the blitzers

Because the blitzers leave their zones, the area directly behind them can be open. A quick pass over the middle to a receiver who runs a short crossing route can beat the blitz, as long as the quarterback gets the ball out before the blitzers arrive. The challenge is that the dropped lineman is in that region, so the quarterback must read whether the zone is covered.

Attack the dropped lineman

A defensive lineman in coverage is usually the weakest pass defender on the field. Offenses look for a way to isolate him: a running back running a flat route against a defensive end, a tight end running a short out. If the quarterback recognizes the matchup, he can throw to the player the lineman cannot cover well. The defense knows this, so it uses the dropped lineman where the throw is least likely.

Run the ball

A zone blitz thins the defense against the run, since a lineman leaves the line of scrimmage and the blitzers may overrun the play. A well-timed draw or a counter play can gain large yardage. Offenses watch for the signs and may check into a run when the defense shows a pass-friendly alignment.

Screens

A screen pass is a natural weapon against any blitz, because the rushers are running toward the quarterback and away from the receivers. A zone blitz can be more difficult to screen, since a dropped lineman is in the area where the screen is set up, but the principle still works when the timing is right.

Slide protection and max protection

Linemen can slide their protection in one direction to account for a blitzer, and running backs can stay to block. These adjustments reduce the number of receivers but give the quarterback time.

Pre-snap recognition

The most valuable response is knowing the blitz is coming. A quarterback who sees a defensive end standing in a two-point stance, rather than the usual three-point stance, may suspect that he will drop. It is the same concept explained in quarterback progressions: the quarterback's first read begins before the snap.

Common forms of the zone blitz

Names and details vary from program to program. The following list describes the shapes most coaches recognize, not a universal vocabulary.

The "exchange" version needs a little explanation. Two defenders on the same side of the line swap duties after the snap: the defender who looks like a rusher drops, and the one who looks like he is dropping rushes. The effect is a form of misdirection.

The 3-4 and the zone blitz

The zone blitz has a particular connection to the 3-4 defense, discussed in the 3-4 defense explained. In a 3-4, there are four linebackers, and any of them can rush or drop. That makes it easy to create a rush from an unexpected player while another linebacker or a lineman covers. The offense cannot tell from the alignment who is coming.

However, zone blitzes are not limited to the 3-4. Many 4-3 teams use them. The call works anywhere there are enough athletic players to execute it.

Risks and limits

The zone blitz is not a free lunch. A few of its weaknesses:

• A lineman in coverage is a gamble. If the quarterback recognizes the matchup and throws to a back or tight end against him, the lineman may be out of position.
• There are fewer players in coverage. Compared with a four-man rush, there are fewer defenders in the secondary. A beaten defender has less help.
• Execution requirements. One misstep can open a hole.
• Predictability. If a team uses the zone blitz too often on the same down, the offense will recognize it and prepare.
• Weaknesses in the run game. Defenders in space and linemen in coverage mean fewer players at the line of scrimmage.

Coordinators therefore choose their moments. They may run the zone blitz on third down and long, or when the offense is in a formation that tends to throw. They may avoid it when the quarterback is mobile, since a quarterback who scrambles can find open space.

Misconceptions

• "A zone blitz is the same as any blitz in a zone defense." Not exactly. A zone blitz specifically involves a defender who is not usually a rusher and a lineman who drops.
• "The lineman who drops is being wasted." He is occupying a zone and removing an easy throw, and his absence from the rush is part of the disguise.
• "The call always sacks the quarterback." Often the goal is a hurried or hesitant throw.
• "Only NFL defenses use it." Variations are used in college and high school football, wherever the players are good enough to execute the assignments. In younger leagues, rules may restrict blitzing, so check your league.

Spotting one on game day

Watch the defensive linemen when the ball is snapped. If one stands up and moves away from the line, you have probably seen a zone blitz. Then look for the blitzer who took his place in the rush, and check where the quarterback throws.

The short version

• A zone blitz rushes five or more defenders, including at least one who normally covers, and drops a lineman into a short zone.
• Its purpose is to keep pressure on the quarterback without leaving the hot receiver uncovered.
• The standard fire zone uses three deep and three underneath defenders, as in Cover 3.
• The call confuses blockers, whose protection count and assignments assume the wrong players will rush.
• Offenses respond with quick throws, attacks on the dropped lineman, runs, screens and slide or max protection.
• Its main risk is a lineman in coverage; it also needs communication and good timing.
