defense / pressure
Five rushers attack from one side while a defensive end drops into a three-deep, three-under fire zone.
Animated assignment view

How it works
The defense exchanges traditional responsibilities: the nickel and linebacker pressure, the weak end drops, and the secondary rotates into three deep zones. The unusual distribution tries to produce a hurried throw into zone eyes.
Create overload pressure without surrendering all deep structure or relying on pure man coverage.
Some defenders who usually rush drop back, while defenders who usually cover rush. The swap can confuse blockers but still leaves zone coverage behind it.
Fire-zone spacing survives only if the seam defenders match vertical releases long enough for the deep thirds to gain leverage.
Call structure
The defense shows a conventional four-man front before exchanging the weak end for two second-level rushers.

How the Fire Zone Creates Confusion
A zone blitz, especially a fire-zone pressure, is designed to make the offense block the wrong people without leaving the defense completely naked behind the rush.
In this version, pressure comes from an unexpected source such as the nickel and an inside linebacker, while a defensive end drops into coverage. Behind it, the defense rotates into a three-deep, three-under zone. To the quarterback, the pre-snap front may look like a conventional rush. After the snap, the picture changes quickly.
I like this call on third-and-medium, against teams that rely heavily on slide protection, and when the offense is comfortable because it expects the same four defenders to rush every play. The overload can attack the protection's rules while the zone defenders keep their eyes on the quarterback.
The strength of a fire-zone blitz is not that a defensive end suddenly becomes a great coverage player. The strength is that the offense has to identify who is rushing and who is replacing. A blocker may turn toward a defender who drops while the real pressure enters from the edge or interior.
There is a price. With only three underneath zone defenders, quick spacing concepts can find open grass. The dropped lineman may be asked to cover an area where a slot receiver is far more comfortable. If the quarterback recognizes the pressure immediately, he may be able to throw into the vacated space before the zone can close.
I want to use this against quarterbacks who hold the ball while diagnosing pressure and against protection schemes that are rigid. I am less enthusiastic against quick-game offenses that spread the field, identify the hot area immediately, and make the ball come out in rhythm.
The defense also has to disguise the call. If the nickel creeps to the line too early and the end starts looking like he plans to drop, we have given away the trick before the snap.
A good fire zone blitz creates confusion without sacrificing all deep coverage. It is not an all-out gamble. It is a calculated exchange of responsibilities: send pressure from where the offense did not expect it, replace that space with zone coverage, and make the quarterback solve the new picture under stress.
