What Is a Blitz in Football?
Updated: Oct 10
A blitz is a defensive pressure call that brings additional rush threats, often from linebackers or defensive backs. Many statistical services classify five or more pass rushers as a blitz. Coaches and broadcasters sometimes use the term more broadly for a nontraditional rusher, so check the definition behind a blitz rate.

Four defenders can create pressure without a blitz. A defense can also show several possible rushers before sending only four.
The tradeoff
Sending an extra rusher can force the offense to identify protection quickly or block an unfavorable matchup. Unless another defender drops out of the rush, it also leaves fewer players available for coverage.
An overload concentrates threats against one side of the protection. A corner or safety pressure brings a defender from a position the offense might expect to cover a receiver. A delayed pressure waits for the protection or a back’s assignment to develop.
The defense needs a connected coverage plan. Extra bodies near the quarterback are not enough if an uncovered receiver gives the passer an immediate answer.
Common pressure families
A zone blitz combines pressure with zone responsibilities, often dropping an expected rusher into coverage. A simulated pressure can change which four players rush while preserving more coverage resources.
A Cover 0 pressure leaves no deep safety help. Receivers still have coverage assignments; zero does not mean all eleven defenders attack the quarterback.
A green dog is conditional: a defender can add to the rush when the assigned receiver stays in protection, under the defense’s rules.
How the offense answers
The offense can adjust protection, throw to a hot route, use a screen or exploit a running lane. The correct answer depends on where the pressure comes from and which space it leaves.
A quick completion does not automatically prove the blitz failed; a tackle short of the first down marker may satisfy the defense. Conversely, a hurried throw that becomes a long touchdown is not a success merely because the rusher arrived near the passer.
Count who actually rushes after the snap, then identify the coverage behind them. That shows the pressure’s real cost and benefit.
