Cover 0 is a coverage that’s often played by teams at all levels. It requires a high level of skill to play effectively. Cover 0 is a type of coverage that requires no deep help.
Cover 0 is man coverage. It’s called cover 0 because there is 0 help deep. Players will play man-to-man coverage against the receivers while the rest of the player’s blitz. It’s high-pressure coverage that forces the quarterback to get rid of the ball quickly.
In this article, we’re going to break down cover 0 and how it’s played across the landscape of football.
What Is Cover 0?
As the name states, cover 0 is a coverage that has 0 deep defenders. If we’re looking at the other coverages, cover 1 has 1 deep defender, cover 2 has 2 deep defenders, cover 3 has 3 deep defenders, and so on.
Cover 0 has no deep defenders that act as a safety valve. Each player that is covering one of the 5 eligible receivers is simply on an island by themselves. They will have to mirror the receiver wherever he goes.
Often when teams play cover 0, they are blitzing the quarterback. The reason for playing cover 0 is to disrupt the quarterback’s timing, which we’ll explain later in the article.
Cover 0 is often played in longer down and distance situations, as it has a high risk and high reward outcome.
Teams must have good cover defenders to play man coverage successfully. It’s one of the hardest coverages in football to play, especially with the explosion of the spread offense. Teams have athletic players as receivers more than ever.
Why Teams Play Cover 0
Cover 0 is often paired with the blitz of 6 defenders. Teams will often elect to keep 6 blockers in to protect their quarterback if they run any spread system.
This allows for all of the defenders that are blitzing to have a one on one situation.
One-on-ones for a defensive lineman is ideal because it allows them to worry about one player blocking them. It also puts a tremendous amount of pressure on every single lineman to sustain their block.
When teams bring 6 players on a pass rush, they leave the running back to block either a defensive lineman or a blitzing linebacker. Running backs are rarely good blockers, so this puts the situation in favor of the defense from a pass rush standpoint.
Another reason teams will elect to play cover 0 is to force the quarterback to make a mistake. Especially at younger levels, the fear of seeing 6 defenders rush towards the quarterback is maximized.
Quarterbacks who are not trained on handling blitz situations will often panic and throw the ball up in the air to get rid of it.
Also, quarterbacks who aren’t trained will try to run away from the blitz, resulting in a major loss in yardage. This is a complete advantage for the defense if they’re facing this type of quarterback.
Disadvantages Of Playing Cover 0
The lack of support deep can really hurt cover 0. If a player happens to beat a player playing man-to-man football coverage, the quarterback can miss anywhere deep.
This is where we often see the ball being floated in the air, as the quarterback knows there’s no help or support deep.
It allows the quarterback to be freer on his releases, as he doesn’t need to worry about fitting the ball away from the safety.
Another reason playing Cover 0 can be a match-up nightmare is for a defensive player that isn’t as skilled as the receiver. This is where the quarterback can take advantage.
Teams often have a wide receiver that can physically and mentally dominate defensive backs. Leaving this player alone with another defensive player is asking for bad things to happen.
Defensive coaches need to enforce their players that defensive linemen and linebackers must move at full speed to disrupt the quarterback. That way, the defensive backs aren’t left covering speedy receivers for too long.
Giving a quarterback time to throw the football in Cover 0 is a nightmare for defenses.
Teams have chosen to use robber coverage (also known as palms) to make it even harder for quarterbacks.
How To Beat Cover 0
As with all of the coverages we teach, we also need to teach our players how the coverage is beat; that way, we can cover up the holes if we’re exploited.
There’s nothing worse for a defensive play-caller than consistently getting beat on coverage and not being able to fix it. If something is broken, immediately put a patch on the defense or show players how not to expose it.
Beating cover 0 requires two things, skill, and patience.
The skill aspect comes from the receivers. Oftentimes cover 0 is successful for the defense because the wide receivers don’t know how to get off a jam. Players are jammed at the line of scrimmage and don’t get very far.
This throws off the timing of the routes and leaves the quarterback in a bad position to throw the football. The average time to throw the football is 1-2 seconds, and time is extremely precious when a blitz is coming.
The second attribute is patience. The quarterback can’t panic when a blitz is happening. A scared quarterback will often make poor decisions and throw the ball to the other team if not careful.

We recommend having an immediate action plan for the quarterback to go through pre-snap. This will help the quarterback think more clearly about where to deliver the football, so they don’t get confused when the ball is snap.
If you’re unsure how to teach cover 0 and the progressions for the quarterback, Chris Johnston from Complete QB gave a great clinic on the different ways to approach man coverage here.
Once you understand how the offense will beat you playing cover 0, it’s much easier to defend against it.
Cover 0 is a high-risk, high reward coverage that can be used in any down situation, as long as the coach feels comfortable putting his players on an island to cover the other team’s receivers.
Last, if the coach feels as if the quarterback can’t handle the pressure of the blitz, this is the best time to blitz the opposing quarterback.
