How to Package Your Blitz Calls

Offenses are packaging their plays, why can’t the defense?

Packaged plays are all the rage right now in the world of offensive football. The emergence of the RPO has created a disparity between the offense and defense. As offenses find ways to package their plays and react off the alignment of the defense, it is putting tremendous pressure on defensive coordinators to call the correct pressure at the right time.

Spread teams are constantly looking to create matchup problems with formation into the boundary (FTB), wide splits, and tempo, the defensive schema must begin to change in concerns to playcalling if the defense is going to keep up, especially in regards to how defenses line up and attack formations. Defensive coaches who call plays/pressures by field/boundary or strong/weak need to adjust their theories.

Calling plays to a direction is no different than guessing and is short-sighted because no-huddle teams can run several different formations, and get into different personnel sets without subbing. In reality, by calling a “strong side” blitz a defense could be running it right into the exact thing it doesn’t want to, an extra blocker or puts their coverage into a critical situation. When offenses play with a tight end, or H-back, they can run a Spread set one play (10p), TE set the next (11p), and switch to a two-back power formation to finish it off (20p); all this while the offense tempos and the defense must adjust on the fly.

Defenses that don’t adjust their playcalling to formations have a tendency to call blanket coverages and blitzes. This can work for a while, but once an offense realizes the defense isn’t necessarily adjusting it can take advantage of the “country” coverages or un-formationed pressures. In the case of the diagram below, TCU had to defend an 11 personnel, 10 pers., and finally a 21 pers. set back-to-back-to-back with tempo. If a DC is not formationing his calls, he could get into something that is fatal or even worse not call anything and ends up predictable (static).


If a defense doesn’t package its blitzes, or formations its calls, then it is at a huge disadvantage. Guessing against tempo and RPO teams is deadly. On paper, the best way to approach calling blitzes is to allow the offense to get set and then call the blitz. That sounds great, but against tempo teams, it is impossible to wait. How does a defense call blitzes that react to the offensive formation? Simple, package the blitzes that come from the same blitz or movement tree.

Offenses combine different plays all the time. By combining several plays into one call, the offense can quickly react off the “box” numbers, defensive alignment, and/or coverage scheme. Essentially they can run a different play every time the ball is snapped without subbing (or even changing formation). One of the best examples of packaged plays by an offense was seen in the 2013 BBVA Compas Bowl in 2013. Ole Miss stays in the same formation, yet runs four different plays.

Combine this scheme with changing the formation and the defense can get off kilter fast if not structured right. Defenses can package calls or pressures too. One way is by packaging blitzes from the same tree and keeping the base defensive structure and rules. See the example below. The diagram illustrates the same blitz, “America“, but run to fit what the offense gives it. Like a defensive RPO. In this case, the blitz reacts off of the formation (2×2 and 3×1).

Building a Better [Zone] Blitz

Evolving the age old Zone Blitz.

America’s Blitz

Walk into most defensive staff rooms, ask what their #1 blitz is, and it will most likely be some variation of this:


The image above is “America’s Fire Zone Blitz.” A Sam/Mike edge blitz with full line movement, and the defensive end to the boundary dropping to the low hole (replacing the Mike). A “Fire Zone” is simply a blitz that sends five men and plays three under-three deep behind it (Cover 3).  Many times a defensive lineman is used to drop to the low hole (MOF), or to replace a blitzing linebacker (curl/flat). Other variations, like the one below, drop the safety into the box and have the DE sink to the curl/flat.

The emphasis for a defense in this type of blitz package is sending more players than an offense can handle to a certain side. Most offenses have hot routes to counteract a blitzing LB. To counter this, defenses started to drop D-lineman, or exchange the LBs responsibilities, into the vacated spots or rolling secondary players to the hot receivers. Here is an example of a Cross-Dog blitz (the term “dog” = LBs) with the DE to the boundary replacing the Will’s coverage responsibility.

Bill Arnsprarger is considered by football historians as the Godfather of the Zone Blitz. In 1971, Arnsparger began using a hybrid DE named Bill Matheson in coverage. This created a de-facto 3-4 and would eventually lead to a new era of defensive football in the NFL. The schemes relevance was solidified in ’72 with the only undefeated season in NFL history. The “No Name” defense ushered in the “Zone Blitz Era.”

The reason Fire Zones are so prevalent is they are easy to run and can use any player on the field. They are also considered a “safe” way to blitz. Arnsparger, considered the blitz safe because he was still playing zone behind a pressure. Legendary DC Dick LeBeau visited Arnsparger early in his career to gain knowledge about the scheme. The words “safe pressure” resonated:

Bill’s catchphrase was that he wanted to get ‘safe pressure,’ on the quarterback, and that expression stuck with me because that was a very succinct way to summarize exactly what I was looking for. Safe pressure. I walked out the door saying those words to myself.” – Dick LeBeau

To run a Fire Zone, a defense has to have two curl/flat players (or seam players), a low hole player (MOF), and three deep third players. This allows a defensive coordinator to get creative because the blitzers can come from anywhere on the field. If looked at as a numbers game, the offense should be able to handle the rush. Where Fire Zones work is by overloading a side, forcing the quarterback to move, and creating short inaccurate throws to hot WRs. The dropping D-lineman assists in the overload by trying to bait the nearest O-lineman into taking him, only to drop and leave a gaping hole for an oncoming rusher.
