Football coverages explained: Cover 0 to Cover 4

Before every snap, the quarterback has a few seconds to answer one question: what is the defense doing? That answer is called the coverage, and it tells you where the open receiver will be. This guide explains the five coverages every QB and every fan should know, in plain language.

Step 1: man or zone?

In man coverage, each defender follows one receiver wherever he goes. In zone coverage, each defender guards an area of the field and covers whoever comes into it.

A quick trick: send a receiver in motion across the formation before the snap. If a defender runs with him, it’s probably man. If the defenders just shift a little and stay in their areas, it’s probably zone.

Step 2: count the deep safeties

Look at the defenders 10 or more yards from the line of scrimmage. That number is the fastest clue to the coverage:

Deep defendersLikely coverage
0Cover 0 (all man, blitz coming)
1 safetyCover 1 (man) or Cover 3 (zone)
2 safetiesCover 2
2 safeties + both cornerbacks deepCover 4

Cover 0

No deep safety at all. Every defender covers a receiver man-to-man, and the extra players blitz. It’s an all-out gamble: if the ball comes out fast, there is nobody deep to stop a big play.

How to beat it: Throw quickly. Find the hot route (often a slant) before the blitz arrives.

Cover 1

Man-to-man coverage with one free safety deep in the middle as help. Cornerbacks usually line up close to the receivers.

How to beat it: Crossing routes and rubs (like Mesh) make it hard for defenders to follow their man. Slants and quick routes away from the safety work too.

Cover 2

Two safeties split the deep field in halves. The cornerbacks stay short and guard the flats. It protects against short throws to the outside.

How to beat it: Attack the hole between the cornerback and the safety along the sideline (the corner route in Smash), or the middle seam between the two safeties.

Cover 3

Three defenders deep (two cornerbacks and a safety), each guarding a third of the field, and four underneath. Very common at every level.

How to beat it: Four verticals: four receivers going deep against only three deep defenders. Curl-flat and flooding one side also stretch the underneath defenders.

Cover 4

Four defenders deep (two cornerbacks and two safeties), each guarding a quarter of the field. It shuts down deep passes but leaves space underneath.

How to beat it: Take what they give you: curls, flats and quick outs underneath, where the defense has fewer players.

Watch out: defenses disguise

Good defenses try to fool the quarterback. They might show two safeties before the snap and then rotate one down at the snap, turning Cover 2 into Cover 3. That’s why QBs look again right after the snap to confirm the coverage.

Practice it

Reading coverages is a skill: the more plays you see, the faster you recognize them. In PreSnap you see each of these defenses from the quarterback’s eyes, pick the right throw and get instant feedback from a coach’s whiteboard. It’s free, with no sign-up.
