How to adjust to TE sets without a natural adjuster.
Spread and Pro-Style offenses utilize a Tight End versus three-down defenses because the defense lacks a natural adjuster. Unlike a four-down defense that can distribute their anchor points evenly across the formation, the 3-4 lacks the extra lineman to defend the extra gap (hence the name “Odd Front”). When faced with an 11 personnel formation, many 3-4 defensive coordinators choose to spin to single-high coverage to gain an extra man in the box. Another adjustment for many DCs in this situation is to attach the outside linebacker to the TE’s side. With the loss of a coverage man and overhang, the DC is forced to spin. When defending an 11 pers. offense from a 4-2-5 or 4-3, these little adjustments aren’t needed because the anchor points are evenly distributed and don’t need to be created.
In a four-down scheme, the defensive ends act as the walls of the box. When a TE is introduced into the formation, the DE to the TE’s side moves to a 9 technique (unless it is Trey and then he is in a 7 or 6i). The four defensive lineman allow the defense to stay even and adjust with the linebackers and secondary. The evenness of the four-down is why many spread teams attack 4-2-5 and 4-3 defenses from 20 pers., utilizing an H-back. In 20 pers., the offense can use the “H” to attack either side of the defense, reading the overhangs to determine what play to run. If the “H” was attached to the formation (TE) he would lose his two-way go.
Defending 11 pers. formations from a 3-4 boil down to understanding how certain fronts react to the extra gap. From a single-gap fit 3-4, a defense can easily adjust to TE sets and stay within a two-shell scheme. The lack of an adjuster is an issue, which is why many 3-4 teams that face the spread, and Pro-Style spread, choose to defend from an Okie Front because it reacts much like the four-down Under Front. Using the offense’s formations as a guide, it is easy to build simple rules within the defense, setting the strength and when to attach the OLBs, to alleviate the issues seen in many 3-4 defenses. Combining an Okie Front with a match quarters scheme can adapt and flex with any formation an offense throws out, it just boils down to how a DC chooses to line up.
MatchQuarter’s guide to breaking down your opponent’s run data.
Of the two play types, breaking down the run concepts is much easier than the pass break down. There is less individual player variance and most run concepts are blocked relatively similar across offensive playbooks. The front of a defense many times will dictate the types of gap and option plays a defense might see. When looking to break down the run it is important for defenses to consider what defensive schemes are showing up in their opponent break down. If the teams in a league or district all run similar defensive schemes then the breakdown will stay relatively true across opponents. It is when teams run different fronts that the run breakdown can give false tendencies. One thing a defensive staff must keep in mind is how offenses change run schemes when facing a four-down front and a three-down front.
In order to keep the breakdown streamlined and efficient, each data point must help the staff paint a clear picture of what the offense is doing. Much like pass concepts, each offensive type (Slot-T, Air Raid, Pro Spread, etc.) has a unique way of blocking traditional runs. Formations add to the variations in blocking schemes as well. For instance, in a two-back power, the offense may choose to “J” block with the H-back and down block with the Tackle, while another offense may insert the H-back as a lead blocker and out-block with the Tackle. Each play is Power, but a defense needs to know the difference in blocking schemes. Luckily, most offenses choose a single blocking scheme and stick with it (therefore, no need to tag the variation), but when doing self-scout, it is important to be able to sort the Powers altogether and the variations between them. Even a play like Counter can be run several different ways from a two-back scheme. Is the offense pulling the Guard and Tackle, or are they using the H-back as the fold player? Add RPOs and a defensive coordinator can have a lot of information on one line. A defensive staff must have a structured, almost scientific, way of breaking down an opponent.

MatchQuarters guide to breaking down your opponents passing data.
Once the down and distance data (D&D) and formation data is placed into a breakdown, the task turns to breaking down the plays an offense runs. Breaking down the run can be easy as long as the coaches inputting data speak the same language. At the root level, power is a power, counter is a counter, and zone is a zone. The biggest task in breaking down the run is if the team is a read/option team and deciding who the conflicted player is (who are they reading). In many cases, especially at the high school level, the plays are basic and can be easily labeled. Pass plays, on the other hand, are a whole different animal.
Unlike run plays that have a base set of rules and can easily be determined, pass concepts can get muddy fast. With so many moving parts and different tags to concepts, it is hard for defensive coaches to look at pass data and not have a convoluted mess. With so many variations within offenses and different tags for certain players, it can make a defensive coordinator feel like he is lost in a sea of data. Add the factor of formations (2×2 versus 3×1 pass can be mush different) and it multiplies the problem. Continue reading “Breaking Down the Pass”

Finding defensive lineman is hard, especially at smaller enrollment high schools. The trend from four-down to three-down is always fluctuating. As more teams turn to spread because of the lack of lineman, it is only natural for defensive coordinators to go small as well. Adding athletes to the field is never a bad thing, and if the “heaviest” set a defense will face is a two-back 20 personnel set, then why not keep a faster defense on the field? The trend is playing out on Saturday’s too. Look at any conference that is heavy spread and the defenses are just smaller. They have to be. The phrase, “Speed kills,” has more validity than every before.
The spread offense is based on the inside and outside zone, plus the reads and RPO’s that go along with them. Many add gap plays, but the offense is predicated on the cutback. This can be a devastating play to defenses that have immobile defensive lineman, or linebackers that over pursue. The point of a zone play is to engage the point of attack, allow the defense to commit, then wall off the over pursuit. The cut-back lane is the sweet spot for the offense. In this day and age, the great defensive minds turn disadvantages into their own advantage. If a team is zone heavy, why not plug the middle and force the cutback early, if not drastically? Most high school offenses rely on a speedy back to hit the outside or cut it all the way to the backside. Again, why not make that an advantage for the defense? The 3-4 Tite, can be a simple way to eliminate the inside zone, make the read for the QB harder, and force the teams that like to run outside to run outside to open defenders.

Inside zone is not a new play to defensive coordinators; neither is the split zone, but it can give defenses fits if not fit up correctly. In its simplicity, it is a creative play to challenge a defense. Unlike its zone counterpart, the split zone creates an extra gap. The play itself is much like the counter without the pulling guard. When offenses run counter the linebackers can react to the pulling guard and fit the extra gaps. The split zone forces the linebackers to fit their gaps. This puts pressure on the secondary (mainly the safeties) to ensure their fits are correct. In the clip below, Iowa St. runs a gap plug blitz and the defensive end to the H-back runs up the field to hold the “C” gap. The out block by the “H” creates an extra gap. The safety to the play should have fit the inside shoulder of the “H” because the DE was taking the outside. Instead, the safety stays outside and is blocked out, leading to Baylor’s first score of the day. Bottom line, split zone has to be treated as though it is a gap play (think power/counter) or a defense will be gashed.
Teams that run inside zone are looking for the cutback. Versus a zone play, the linebackers have to fill their gaps (there is no puller). The offensive line creates a wall and allows the running back to cut back to the open weak side. In the clip above, ISU was running a run stop blitz, but because the safety didn’t fit his gap, it led to a touchdown. Teams that run split zone and the read-option offshoot, need to be played as though they are gap scheme heavy teams. Add RPO’s to this play, and it puts tremendous pressure on a defense, all from a simple zone scheme. There is hope, much like the zone read, a defense can attack this play on the principles of the offense. Continue reading “#FMT – Defending Split Zone”
Transition seamlessly from defending the spread to stopping power football.
There is not a more difficult time than the present to be a defensive coordinator. The amount of offensive formations, schemes, and alignments has never been greater. Present day defensive coaches can see an offense that bases from an empty set (3×2/4×1) one week to a power set (2×1 with two backs) the next. When changes in the scheme are so drastic it is easy for a defensive coordinator to find himself changing his base every week. With the advent of spread offenses, the power sets (2×1 with a tight end and H/fullback) are becoming less prevalent. It is difficult for a 4-2-5 team to play a wide open spread team one week, only to turn around the next week and face a smash mouth power/counter team. With a good set of base rules, a defensive coordinator can seamlessly maneuver the nuances of defending any formation thrown his team’s way.
