Base formations

The zone blitz is usually executed from one of three zone coverage formations.


Cover One

Cover one is identical to cover zero (where there is no man covering deep into the field, making the coverage mostly man-to-man) with one major exception. One player, typically the weakside or "free" safety is left with no man responsibilities, and can instead roam the intermediate to deep zones.


Cover Two

Fire zone

A fire zone blitz is a specific zone blitz in which the defense rushes 5 with a 3–3 coverage behind it—three deep defenders and three underneath defenders. Although the fire zone can be run out of many fronts and alignments, the main points are the weakside defensive end or end man on the line of scrimmage away from the blitz dropping off into coverage, and pressure coming from the opposite side of the field. For example, in a 4–3 front, the backside defensive end will drop off to the curl and then the flat, while the strong safety will drop down and cover the frontside curl to the flat. The non-blitzing linebacker will take the middle hole and the other two linebackers will stunt with the defensive line to try to pressure the passer. Typically the other three defensive linemen will slant away from the linebacker blitz. This type of blitz can be effective because the defensive line may draw some of the protection away from the rushing linebackers, and the defensive end may drop into a passing lane as the quarterback notices the non-blitzing linebacker drift towards the middle of the field. There are many variants of this blitz from many different looks, but the base concept is a 3-deep, 3-underneath coverage, 5 rushers, and a player up front dropping back into coverage away from the blitz side.


Advantages

The zone blitz is also an effective scheme when defending the
screen pass A screen pass is a play in gridiron football consisting of a short pass to a receiver who is protected by a screen of blockers. During a screen pass, a number of things happen concurrently in order to fool the defense into thinking a long pass is b ...
. In a zone blitz especially designed to defend the screen pass, defensive linemen initially identify the running back or other potential recipients of a screen pass in order to cover them specifically rather than dropping into a zone. Covering a specific player is much easier for a defensive lineman who does not normally play in the open field. The blitzing linebackers are at an advantage in screen situations because they are more likely to actually pressure the quarterback who is trying to lure slower defensive linemen upfield and not expecting the significantly more athletic linebackers. The combination of the hurried quarterback and the quickly-covered screen receiver often results in a sack, an interception by a defensive lineman, a tackle for loss of yardage, or an incompletion. A very good example of this defensive scheme by LeBeau is the 100-yard

Disadvantages

The last advantage highlighted above is also perhaps the principal disadvantage to a zone blitz, in that one or more defensive linemen may be required to drop back into coverage while linebackers take their place in rushing the quarterback. Linemen, by design, are the biggest, heaviest, and slowest members of the defense on the field. Asking them to cover a speedy slot receiver or an athletic, pass-catching tight end is often a losing proposition. Most, if not all, linemen, simply do not possess the speed to legitimately cover wide receivers for more than a few yards. These kinds of personnel mismatches can lead to easy completions if the quarterback can correctly identify them. An additional disadvantage is that a zone blitz is less likely to be effective against the running game than a traditional blitz, since the linemen, often the best defenders against the run, have dropped off of the line of scrimmage in order to participate in pass coverage. For this reason, the zone blitz is most likely to be effective in down and distance situations that dictate a passing play (i.e. third down and more than six yards).
