Three Coverages Every Quarters Team Needs in Its Toolbox

Go beyond static Quarters and be aggressive in your coverage schemes.

Split-field Quarters is one of the most adaptive and flexible defenses a modern defensive coordinator can base out of. It molds and flexes to fit whatever an offense can throw at it. Offenses can only throw so many different numbers on either side of the center; up to four eligible receivers at the most, and Quarters can adapt to all of them. At the fundamental level, Quarters is based off a numbers system. The corners always relate to #1, the safeties and outside linebackers #2 (bracket), and the Mike always relates to #3. If a player can count to three he can play Quarters.

Utilizing split-field coverages takes the Quarters scheme one step further, creating even more adaptiveness and flexibility. Being able to tag a base defense with small coverage manipulations can transform a static Quarters look into a robber, invert (Sky), or trap coverage. Pressure doesn’t always have to be the answer either. The defensive coordinator doesn’t have to outsmart his coaching counterpart on the other side of the ball, just the young QB trying to run the offense.

Many coordinators want to focus on pressures as a way to combat offensive schemes. Don Brown, the Defensive Coordinator for the University of Michigan puts the words “Solve your problems with aggression,” in his install playbooks. Pressures are a great way to force the issue with offenses, but sometimes a defense needs to sit back and run its base. When sending five or more, a defense loses a man in coverage and can get overexposed or become deficient in a certain zone if the blitz coverage is not structured correctly. On early downs, many top DCs like to sit in their base defense. Being static can have its own set of issues too, but adding coverage tags to change leverage points and run fits can be just as “aggressive” as a pressure and force the QB to beat the defense and not the OC.

Aggression can mean a multitude of different things when it comes to defense. The obvious answer is to blitz, but defenses can manipulate the secondary to be aggressive in their pass distributions and against certain receiving threats. Every offense has counters built into their scheme to take advantage of a defense vacating zones or spinning to single-high. Not every problem can be fixed through blitzing. Sometimes you have to play your base. Below are three ways a split-field Quarters team can tweak their coverage while staying sound and aggressive in nature.

MQ Film Study: Defending 20p – Minnesota vs Michigan (2017)

MQ takes a look at how Don Brown’s defense handles 11/20 pers. formations.

One of the toughest personnel groupings in football to defend is the 11/20 personnel Spread offense that utilizes an H-back/TE hybrid to create extra gaps and a multitude of formations. Teams that have a hybrid TE can line him up in the backfield, at slot, or on the line. The flexibility that an H-back brings to a multiple Spread offense is evident in the way the college game is evolving. More and more offenses are turning to hybrid “big” bodies to give defenses different looks on any given play. Going form a two-back three WR formation one play and a Pro Spread TE formation on the other.

One formation, in particular, is the weapon of choice for many teams that run Bash concepts, or “back away” runs, the 20 pers. “sniffer” look. One advantage offenses have by using a “sniffer” H-back is that he has a two-way-go. He can insert into an open gap (Iso), kick out the end man on the line (Power), pull along with another lineman (counter), or arc to seal a linebacker. There are a plethora of ways an offense can attack a defense using this grouping and formation. The addition of an extra blocker into the box also forces some teams to spin the secondary to add extra men in the box (which allows the offense to blow open the top on an isolated secondary player).

Don Brown, the Defensive Coordinator for the Michigan Wolverines, used a unique style of defense (shown below) to combat the Minnesota Gophers multiple 11/20 pers. running attack. The Gophers were entering the game 4-4 and looking to bounce back after a close loss to Iowa (10-17), while the Wolverines were looking to continue their winning ways having beaten Rutgers the previous week (35-14). Minnesota’s offense under new head coach P.J. Fleck is a mixture of TE sets and Spread sets.

When looking at the scheme Brown chose to defend the Gophers 11/20 pers. formations, one will notice the ultra aggressiveness towards the run and the lack of “coverage” for the H-back. Brown also had several change-ups and automatics to motion and the different formations the Gophers threw at the Wolverines. Below is a diagram of how Brown blitzed the Viper anytime the H-back motioned away.

01 [MIvMN] Base DEF

Coach Brown during his clinic talk at the 2018 Lone Star Clinic noted the absence of the TE in the passing game during the Big 10 season. Outside of Troy Fumagalli at Wisconsin and Mike Gesiki at Penn State, one will be hard-pressed to find a TE that merits an extra man in the passing game. This allowed the Wolverines to add an extra defender in the box against most Big 10 opponents without worrying about an “H-Pop” or a TE streaking down the middle of the field.

Throughout the game, Brown’s defense was able to contain the Gophers running game, limiting them to just under 100 yards. As stated, Minnesota rarely used the TE/H-back in the passing game allowing Coach Brown to be ultra-aggressive to the run. Though the lack of an extra defender opened his secondary up to deep shots outside (and some did hit home), the Wolverine defense was able to limit Demry Croft, the Gophers QB, to a measly stat line of 5/12 for 74 yards passing. Below is a film study of how Coach Brown and the Wolverine defense defended the Gophers multiple 20 pers. looks.  Continue reading “MQ Film Study: Defending 20p – Minnesota vs Michigan (2017)”

5 Tips For Blitzing From The Secondary

MQ discusses 5 things to remember when blitzing from the secondary.

Utilizing the secondary in blitz packages is one of the most underutilized tools in a defensive coordinator’s toolbox. As many DC’s will point out, blitzing from the secondary will expose the defense to man-to-man coverage, but if used correctly (and in the right situations) a secondary blitz can hit home. When offenses create pass protection schemes they use the box numbers in front of them to divvy out responsibilities. Whether it is Big-on-Big (BOB), slide, or zone protection, the secondary is rarely accounted for in pass pro. Knowing this, and utilizing the secondary in pressure packages, can give the defense an added advantage and lead to QB pressures or sacks.

Using the secondary near the box is not only for the pass. Much like pass pro, some offenses do not account for the secondary in the box. This can be used to the defense’s advantage. Putting a secondary player near the box and knowing he will not be accounted for is an automatic win for the defense. The use of “trapping” the secondary near the box can also be used to confuse “check-with-me” teams. By placing a secondary player near the line of scrimmage (LOS), the offense must decide if the defense is blitzing or will drop the player back into coverage. By utilizing the secondary in pressure packages a DC can create a simple confusing alignment that offenses have to respect. If done right, using the secondary to leverage the boundary can add to the box numbers without spinning to single-high and exposing the defense to verticals down the seam (or a LB guarding a speedy slot WR).

Defending Trips – Special Coverage

If the offense won’t throw to #1, lock him up and reduce the field.

When defending a team that runs Trips it is important for the defense to have multiple coverage options. Depending on how an offense chooses to attack a defense the selection of the right coverage can be crucial. Being able to switch from base coverage to base coverage allows the defense to keep the offense on its toes. If a defense only runs one base coverage against Trips, offenses will quickly find a way to exploit it. This fact alone should encourage a defensive staff to carry multiple coverages into a game and be able to use them when the opportunity arises.

Many times offenses use the #1 receiver as a decoy or chooses to run him off to create a void so the #2 or #3 WR can run an out route into space. One way to counteract the nonuse of #1 and outs by #2 or #3 is to run Special Coverage. Unlike Stress where the Sam is blind to what the #3 WR is doing, Special eliminates the #1 completely and reduces the field. The Sam takes on the responsibility of a Two-Read CB. His eyes are squarely on #2 and will carry the vertical of #2 if the offense runs vertical routes. Like Stress, the key player is the Sam linebacker and his ability to run with a vertical route. Eliminating #1 puts the Sam on an island with #2. As stated earlier, having options in coverage is important to defending the spread. A defense must be able to adapt to any situations and adjust to any formation/scheme thrown at it.  Continue reading “Defending Trips – Special Coverage”

How I Teach Match Quarters – Pt. 1

A clinic on the pedagogy of match quarters. Pt. 1 — Teaching the CBs.

01-sky

Teaching the Corners

Four Read (Sky)

The corner’s alignment in Sky should be front toe at six yards and shaded to the “inside eye” of the receiver. The term “inside eye” means if the CB were to walk up to the WR his outside eye should look directly into the inside eye of the WR. This allows the CB to hold inside alignment without giving up too much space in between. Six yards is a good depth because it is not too deep that it automatically gives up the underneath and not too close that the CB ends up in “no man’s land.” The CB’s stance is an “open” stance or the inside toe on the01-stance heel of the outside foot. I’m not a big proponent of getting the butt to the sideline and shuffling out (basketball style) because match quarters is different than true zone. It is essentially a hybrid man scheme, where the CB takes the #1 WR a majority of the time (and the safeties bracket the #2 WR with the outside linebackers). I like to keep my corners square in order to break on the out and slant routes. I find that as players shuffle out basketball style and butt to the sideline, they start working to the sideline and give up the advantage of inside alignment. The point of match quarters is to force the least percentage throw, the fade or deep comeback, thus, I keep them square and we “slide” out.

The initial step of the CB is to slide out, or step-replace for three steps. Most offenses will attack quarters in the soft underneath zone. The slide technique is essentially a three-step read. We are pushing off with the front foot and stepping back with our inside foot. These are quick steps and our feet are never too far off the ground. The corner should have “hot” feet and stay in his “tuck.” This positioning allows the CB to drive on any ball underneath, essentially off-man. After the initial three-step read, the CB transitions into his regular backpedal, reading the WR’s departure speed.

The CB’s eyes are looking at the #2 WR through the QB. This completes his “triangle.” It is important for the corners to be able to see through their entire peripheral vision. Keeping an eye on the departure speed of #1, while reacting to the route of #2. In Sky coverage, the CB is the deep player. His responsibility is to “top” the deepest route or drive on anything underneath by the #1 WR. The only route combination that changes the assignment of the CB is a stop/corner, or China/Smash route. In that case, the CB would give a “stop” call, flip his hips to the sideline and mid-point the stop and corner route (same as in Cloud or Two Read). If the team is running a stop/bender concept to hold the OLB in the curl, the CB should drive on any ball thrown to the #1 WR. Everything is predicated on the #2 WR. In the video below you will see a good example of sliding out and keeping inside leverage by the field corner.

Defending Stack and Bunch Sets

Theories on attacking the spread’s cluster sets.

One of the hardest sets in football to defend is the cluster or stack set. Spread offenses utilize this set to get the defense’s outside linebackers in run/pass conflicts. Unlike a traditional 2×2 set, the defense has to adjust to the width of the receivers. Stacking them creates width, and width creates the conflict. Spread teams rely on the open “B” gap to build their RPO’s and offensive gameplan. By stacking the receivers out wide, the defense is forced to adjust. In a two-high system, the player in conflict (usually the Will LB) has to choose, cover down to his receiver or hold tight to the box. If he stays close to the box, the offense is going to throw the quick screen and create a 1-on-1 open field tackling matchup with the safety or corner. In most cases, the defense wants to avoid this as much as possible. On the other end of the spectrum, if the defender widens to the cluster set, the offense has a 4-1 box and a clear running opportunity. Versus a two-high system, there is a great chance for the offense to part the field like the Red Sea for a big gain. Ask any offensive coach, a 4-1 box is a magical thing.

In the image below, Penn St. runs and Under front and “hips” it’s Sam LB to the strength. In most RPO style offenses, this is a clear pass read. The Sam has to honor the run read and step to his gap. Even with zone away and a gap exchange with the crashing DE (in this set the DE has dive), the Sam has to take a step towards the box. The QB is taught to read the Sam’s path and throw the screen. Penn. St. is most likely in a “Cloud” coverage (Two Read) and the safety is bailing on the snap. Easy pickings for any decent offensive coordinator. It’s a conflict of philosophy; the offense wants 1-on-1 matchups and the defense wants a plus-one. In order to create a six-man box and protect against the run, the defense has to spin to single-high, but to keep a plus-one in pass distribution it has to stay in two-high, something has to give. MatchQuarters explores the options.

Leveraging the Boundary

Using the boundary CB and Safety to confuse RPO and check-with-me teams.

Basing out of a defense that has split field coverage has its advantages when it comes to 2×1 and 3×1 sets. Many spread offenses split the field themselves, only reading one side of the formation. This allows defenses to take advantage of the one read RPO systems that many spread teams utilize. No matter what the defense throws at a split field match quarters team, it can align in the correct coverage. Another way to protect the defense is to formation the defensive play calls.

The single receiver and slot receivers are the main targets for RPO spread teams. They use the leverage of the secondary against the defense, reading dropping safeties and the depth of the corner. The single WR side usually sees the quick hitch or slant off of play action. Teams like Baylor use the leverage to RPO vertical choice routes. A defense can confuse the QB by playing with the leverage of the secondary pre-snap. This may seem like single-high to the untrained eye, but with a split field coverage scheme, a defensive coordinator can change the leverage to the boundary (single receiver side) and still run the base quarters scheme.
