What is a blitz in football?
In football, a blitz is a defensive tactic where the team sends five or more defenders, instead of the usual four, into the offensive backfield with the primary goal of pressuring or tackling the Quarterback. Under normal conditions, the defense relies on four players from the defensive line (typically defensive ends and tackles) to rush the Quarterback. These players aim to beat the offensive line's protection and either disrupt the pass or bring the Quarterback down, which is known as a sack.
A blitz adds extra Pressure by involving players from other positions, such as linebackers or defensive backs, making it harder for the offense to predict and block effectively. The goal is to speed up the Quarterback's decision-making, force inaccurate throws, or create turnovers. While a blitz can be high-risk, since it leaves fewer players in coverage, it can also be high-reward when timed and executed correctly.
3 Main Reasons Why Teams Use a Blitz
1. Put Pressure on the Quarterback
Football blitzes are a great way to make the Quarterback uncomfortable. When a QB is under pressure, they're more likely to make mistakes, like throwing an inaccurate pass or rushing a play.
2. Disrupt the Offense
Football is all about timing. If a blitz throws off that timing, by forcing the Quarterback to throw too early or stopping a running back before they can make a move, the entire play can break down. Even if the play doesn't result in a sack, it can still lead to a missed pass or no gain.
3. Create Turnovers
When the offense is under pressure and out of rhythm, it opens up chances for the defense to take the ball away. A rushed throw could be intercepted, or a pass might get tipped into the air and grabbed by a defender. Blitzing in football increases the chances of turning defense into offense by forcing errors and seizing control of the game.
Types of Blitzes
Blitzes are a fundamental defensive tactic, but their true effectiveness lies in variety and deception. Skilled defenses disguise their intentions before the snap, blending different blitz packages to keep the Quarterback guessing. Whether it's an all-out rush or a strategic send of a single defender, the goal og football blitz is to disrupt offensive timing and force errors. Let's break down the key types of blitzes that experts use to gain an edge on the field.
1). Linebacker Blitzes: meaning & types
Inside Linebacker Blitz (A-Gap or B-Gap Blitz):
This is a common blitz where one or more inside linebackers rush through the gaps between the center and guards (A-gap) or between the guards and tackles (B-gap). The goal is to quickly break through the middle and collapse the Quarterback's pocket.
Outside Linebacker Blitz (Edge Blitz):
Here, an outside linebacker or sometimes a defensive end attacks from the outside edge of the offensive tackle. This puts pressure on the quarterback from the side and is especially useful if the quarterback tries to roll out or if the offensive tackles are left to block alone.
Double Linebacker Blitz:
This play sends two linebackers at the same time, either both inside, both outside, or one from each side. The idea is to overwhelm the offense by creating extra Pressure at the point of attack.
2). Safety Blitz
A safety blitz is exactly what it sounds like — a safety, usually positioned deep in the defensive backfield, suddenly charges forward to pressure the Quarterback or stop a running back near the line. This aggressive move aims to surprise the offense and disrupt their play quickly. Legendary players like Troy Olamalu made this blitz famous with their speed and timing.
However, it's a high-risk play. If the offense reads it correctly or has strong protection, the safety's absence can leave the middle of the field wide open, leading to big gains or even long touchdown passes. That's why safety blitzes require perfect timing and execution to be effective.
3). Zero Blitz
A Zero Blitz is one of the most aggressive defensive strategies in football. In this play, the defense sends every available rusher—often six or more players—after the Quarterback, leaving no deep safety help behind. That's where the name "zero" comes from: zero deep coverage.
It's a high-risk, high-reward tactic. If the blitz gets home quickly, it can lead to a sack, a rushed throw, or even a turnover. But if the offense picks it up or reacts fast with a quick pass, it can leave the secondary exposed, often in one-on-one matchups with no help over the top.
Coaches typically call a Zero Blitz in clear short-yardage situations or when they believe they can catch the offense off guard. When executed correctly, it can completely change the momentum of a game.
4). Inside Blitz
An inside blitz is a classic and highly effective pressure blitzed football tactic. In this play, linebackers target the interior gaps between the offensive linemen, often where the protection is most vulnerable. The goal is to overwhelm the middle of the line with more rushers than it can block. When executed well, this forces the Quarterback to abandon the pocket quickly, disrupting the timing of the play and making it harder for him to read the defense or throw accurately on the move.
5). Zone Blitz
In a zone blitz, the defense mixes things up to confuse the offense. Instead of all the big guys running the line and rushing the quarterback, some drop back into pass coverage. At the same time, the linebacker, who usually covers receivers or plays the run, charges into pressure the Quarterback.
This blitzkrieg football strategy makes it hard for the offense to read what's coming. The blocking assignments get tricky, the Quarterback has to adjust quickly, and the receivers may end up facing unexpected defenders in coverage. It's a smart way to disguise Pressure while still protecting against the pass.
6). Cornerback Blitz
A cornerback blitz, often called a "corner blitz," involves sending a cornerback—usually responsible for covering a wide receiver—rushing toward the Quarterback instead. Like safety blitzes, this strategy sacrifices coverage in hopes of catching the offense off guard. It's a high-risk, high-reward play: the defense is betting that the corner can reach the Quarterback fast enough to disrupt the play before the open receiver can be targeted. When timed correctly, a corner blitz can completely throw off the offense's rhythm and force a quick mistake.
7). Run Blitz
A run blitz is a strategic move designed to stop the offense's running game, not just the pass. When a defense predicts a run play or the direction the runner will take, they send extra players quickly to that spot. The goal is to meet the runner early and shut down the play before it can gain momentum. This aggressive approach can disrupt the offense and keep them from gaining important yards on the ground.
How does an Offense Beat the Football Blitzes?
The goal of a blitz is to get to the Quarterback fast, so to stop it, the offense needs to act even quicker.
Quick Passes
If the Quarterback can spot a football blitz before the snap, he can know where his open receiver will be. He can beat the defenders rushing him by throwing the ball quickly to that open player. This often leads to big plays, especially when many defenders come in a blitz. Running backs are often the target because they're close to the Quarterback and can run short routes to catch the ball before the defenders arrive.
Mobile Quarterbacks
A quarterback who can move well can avoid the blitz by dodging defenders and running out of trouble. When a mobile quarterback escapes the blitz, he can turn a broken play into a big gain by running the ball himself.
Max Protection
Offenses can also use special blocking plans called max protection. In this setup, extra players stay back to block instead of running routes. This gives the Quarterback more time to find an open receiver. The running back and tight end help block the blitzers, slowing them down so the Quarterback can throw with less Pressure.
No matter the blitz, it often leaves a weak spot in the defense. The Quarterback's job is to find that weak spot—either by reading the defense before the snap or quickly after Pressure starts. The best quarterbacks can read the football blitzes as they happen and get the ball to the open player fast.
Conclusion
Football Blitzing is a fundamental defensive tactic that adds excitement and strategy to football. While it carries risks, when executed well, it can instantly change a game's momentum. Knowing what is a blitz in football and how blitzes work helps fans better understand the game's complexities and the skill it takes to outsmart the opposition. Appreciating these defensive moves enhances the overall experience of watching football.
