After covering front matching previously, we can now explore options available to handle slot sets that are separated from the box. Typically, this is best understood from a 2-back look with a single receiver on the other side of the slot (allowing a variety of bracket looks and the linebackers matching back flow). The passing strength is immediately identified (slot) and the safety, corner, and overhang player can communicate how they would handle the 2-man routes out of this. These methods can also be applied independently to each side (split-field) when facing 1-back, as well.
 
With two receivers split from the formation (slot) you end up with a 3-on-2 advantage for the defense. As we covered before, there is a variety of ways to handle this. In attempt to tackle two things at once, we’ll cover these concepts using Saban-speak (out of Nick Saban’s playbooks). It should be noted that Saban’s “system” is extremely concise, flexible, and modular (in its application). What comes with those benefits is a dictionary full of terminology to communicate every conceivable action and response on the field. We’ll use his method as a way to keep a central thematic framework, but these concepts are relative to what everyone else does (so don’t get hung up on the verbiage).
FIST

The first is basic Cover 3 Sky (“Fist”) with what amounts to be the old “country cover 3”. Fist brings the overhang player down outside of #2 receiver serving as primary force. This defender will drop into the seam and not carry any route by #2 deeper than 12 yards and jump the first receiver to the flat. The corner would play all of #1 receiver vertical (or #2) out and up. The free safety would play middle of the field to the #2 receiver. Because these two receivers are handled by these three players, additional receivers (releasing back) would be immediately jumped by the next linebacker inside (Will) unless #1 or #2 released inside.
 
Examples of matching in Fist
Exceptions

• Vs 1 back – the FS will check to Rip/Liz rules (match left/right away side) and man #1 and #2.
  
• Vs Wide slot split (horizontal stretch) – with a great deal of space underneath to cover, a “TOKYO” (smash rule) call can be made to have the corner take all short routes and have the overhang defender carry a vertical stem.

 
Sky (Fist) remains an all-purpose coverage solution to slot, but can face limitations with quick 2-man games against the overhang player.








 
COVER R - ROBBER

We’ve covered robber coverage before and this version would be just like Virginia Tech plays it. This is best against a tight #2 with the FS dropping into the seam and the overhang player immediately expanding to the curl. This isn’t much different than TCU’s ‘2 Read’ (covered before). The FS acts as the robber, reading #2-to-#1, playing the front hook with a #2-to-QB-to-Alley fit progression.
 
The corner immediately drops to the deep third with the overhang defender jumping first receiver to the flat. With the corner committing to the deep half, any vertical route by #2 will be bracketed inside-out by the FS and corner.

Robber coverage remains arguably one of the best run down solutions, especially to the field.  1-back looks can be handled by robber, but do not provide the leverage security that 2-back does.
 
 

COVER 2 - CORA

This is traditional cover 2 cloud with the FS over the top in deep half coverage and defenders in the curl and flat. The overhang player will align inside #2 and the corner outside of #1.  With two outside underneath zone defenders on top of two split receivers, you have the ability to aggressively attack the quick game.  With any slot coverage, you are only as good as your answer to the smash route.  With true ‘Cora’, the force corner will sink in the flat (playing “TOKYO”) and the overhang will carry #2 vertical.

 
examples of matching in Cover 2  
 
Cover 2 is great against quick game and perimeter run game.  How a defense matches vertical routes in Cover 2 will typically be its weak spot.
 
 
One adjustment to this Cover 2 look is known as “Leach”. It is exactly the same with the exception of the overhang defender is man-to-man #2 (slot/curl). This would afford the (usually exceptional) slot receiver to be double-covered underneath or deep with the surrounding zone defenders.
 

COVER 4 - THUMBS

Thumbs is a 3-on-2 quarters principle that can morph itself into swipe bracket when only one receiver is vertical. The FS will double #1 or #2 from inside out with the corner playing deep third outside.  The overhang player is the sole underneath defender and will take first shallow out / in receiver between #1 & #2.

Quarters is great against vertical game and play-action, but the lack of underneath support can cause perimeter leverage issues the offense can exploit.
   

COVER 5 – COUGAR / IOWA
Adding this as a final thought, Cover 5 is the man-under with deep half help. The FS will rob everything inside with the ability to double either receiver deep.  I didn’t provide any illustrations as it is pretty self-explanatory and is the ideal passing coverage.  The FS will rob everything from the inside.  Because the corner (your best cover guy) will be man-to-man on #1 outside wide “on an island”, you will typically have a 2-on-1 cone/bracket on #2 between the deep safety and the overhang player.

Unrelated to everything.... Just passing along an interesting development in artistry.....something interesting is afoot with one of our time's most creative storytelling voice, David Simon (and company).  Simon, of "The Wire" fame (and brilliant treatment of "The Corner" and "Generation Kill"), is deep in his current passion; the unique Americana invention of New Orleans music told through its principle actors (the musicians). The visual-novel of  "Treme" nearing the end of its second season has become an acquired taste for many.  Those missing out on the brilliance in its subtleties (it isn't meant to be swallowed whole, but savored by digesting each scene) of scenes and dialogue are losing sight of what the series (and Simon's craft) is about. I felt it was worth noting as the appreciation of performance art (and original storytelling) is becoming a dying craft.  Perhaps best summarized here by actor Clarke Peters.
My point in offering these thoughts is to pass along an observation of the use of technology as the social apparatus of our time.  The series (like any other event) is being chronicled online in various blogs.  One of which, Back of Town ,  has become a way of appreciating the episodes with many people responsible for telling this story.  With regular, affable interaction with (the real) Davis Rogan, Tom Piazza, David Simon, and Eric Overmyer and from the perspective of a 1-to-1 relationship (and not that of a lecturer or host), giving participants the organic feeling of being involved in the actual process.  This type of discourse wouldn't have been possible even five years ago - its exciting to watch this process develop, especially in the environment that this series has found itself in; a humble and artistic community of writers with a production geared for the exact opposite [commercial] appeal of its on-air counterparts.  I'm not sure what will come of it, nor am I star-struck that the production team would interact with consumers, but how it shapes the course of artist-audience relationship is something to watch.

Last year, we covered Nick Saban’s 1-high defensive principles, so its only fitting we review his 2-high concepts now. The bulk of understanding Saban’s philosophy resolves around digesting his vocabulary. This ‘vocabulary’ provides a comprehensive communication method for technique or concept that remains universal though his different sets.

With the propensity of 1-back attacks, and as illustrated with the 3-deep coverage series, a defense has to have a competent answer to the threat of 4-receiver vertical stretch (2x2 or 3x1 formations). This is why we see most every defense basing out of a 2-high coverage shell. This provides a comfort zone for defenses to match 2x2 formations and will illustrate why the 3-4 becomes a choice to achieve this balance (can adjust to two detached receivers to a side while keeping a 2-high coverage shell).

The easiest way to immerse yourself in his 2-high concepts is to start with Saban’s do-everything Cover 7. Cover 7 is man-to-man match quarters; 4-on-3 strongside / 3-on-2 weakside. At its most basic application, it is just a standard quarters defense. Each side will match according to the split of the formation and game plan. Because it can be adjusted in so many ways, the consistent 2-high shell can give a myriad of looks but remain constant before the snap.

TRIANGLE


To help digest this, its best to think of this in terms similar to the TCU coverage concept (with the exception of MOFO safeties). Away from the passing strength, you will have one receiver split, and at the most, two. This is referred to as the ‘triangle’ side, for the 3-on-2 apex the defense has (safety, corner, backer against a receiver and back). Typically, the dominant receiver will align as the passing strength (X).

With Cover 7, he can easily be accounted for in a few ways;

• aggressive man-to-man with corner (“MEG”) or
• double-coverage bracket between the corner and safety (“CONE”)

A “MEG” (technique) call will be made that declares the corner will man up with the #1 receiver wherever he goes (#1 will be matched by the corner).

A “CONE” call will double the single receiver much like how traditional quarters is played to the single-receiver side (if X is shallow, corner gains depth to his ¼ and safety constricts his deep middle ¼ ).


This leaves the #2 receiver or back-out as the only threat to be matched by the safety and backer (Will). The Will matches the fourth receiver (X,Y,Z are accounted for – so whoever becomes the 2nd receiver away from strength) or the 1st crosser (coming from the passing strength).

If second receiver aligns (outside the box) the Will adjusts and walks out to split the difference. Typically, if a second receiver shows to the ‘triangle side’, any “MEG” call would be adjusted to “MOD”, which simply has the corner playing off-man on the first receiver.

The “MOD” call declares that the corner will not take #1 on anything under 5 yards and will be anticipating some kind of 2-man China/Hi-Low concept from these two receivers (Will would now match #1 receiver short / corner would now match #2 receiver high). These adjustments can be called / declared by the safety, but more often used per game plan.



STRONG / PASSING NUMBERS



Believe it or not, that was actually the ‘hard part’. Quarters into the passing strength is actually quite simple, as it really is just standard quarters rules. With two receivers to the passing strength, you have the vertical stem of #2 being controlled by the deep safety, and any vertical by #1 being handled by the corner (unless in “MEG”). The SLB / Nickel will take the first receiver to the flat, the Mike will match the final #3. This should sound extremely similar to how pattern match coverage is introduced and used in 3-deep zone and fire-zone pressures.

The “MEG” / “MOD” adjustment is available to use on this side, as well. Why would you use this? Why wouldn’t you just hang back in standard quarters? Because the common weakness of quarters in the perimeter distance for the OLB to respond to. By modifying how the #1 receiver is played, you can remain in the same coverage with a minor tweak on the (standard) routes that will be used to attack quarters coverage (underneath). With a corner locking down the #1 receiver, it will become a 2-on-1 match between the OLB and deep safety.

A ton of examples of Cover 7 (with and with out meg/double meg)






Vs 3x1
Cover 7 can adjust to all formations, but what happens when faced with trips, as is common with most ‘spread’ or 1-back formations? The answer is, “ZEKE”, which is just a banjo matchup for the linebackers. We’ve seen this before with the Rip/Liz post on 3x1. It is essentially saying the outside linebacker takes the first out route, the inside linebacker will take the second out route.
The inside linebacker will take the first inside route, the outside linebacker will take the second inside route.
Away from trips, “MEG” will be played against any single receiver The Will matches man-to-man on any back release as the 4th receiver releases.

If the #4 receiver aligns as a slot (now a 2-man receiver threat is present), the “MEG” is off and adjusted to “MOD” technique by the corner.

If the #4 receiver flow strong (to the trips), then they will be playing ‘3 Buzz Mable’, which is just man-match banjo with the safety dropping into the hook area (and Will expanding as force player). This rule also applies to 2-back flow (both backs release to the strong side) action.

This post has been in the works for a while, but possibly more apropos after the Arkansas game where there was considerable controversy of ‘blown assignments’ regarding the Razorback’s first score. On paper, it actually wasn’t an impossible matchup; 2x2 matched with an even Cover 7 coverage, the field corner is man-to-man in MEG. It really became a 3 receiver flood, so the Will would've matched first outside (F), Mike would cut the crosser (Y) and with #2 shallow and away, the Sam would've dropped into the dig.






With having given a basic overview of Saban’s quarters coverage, it will provide context in which to gain understanding in how he handles slot formations (where the real tweaks in the scheme come from). I hope to be able to provide an addendum to this by going over Saban’s Cover 2 package, as well as other slot adjustments from 2-high.


Possibly, in the future we will explore his other coverages, but in the meantime, here are how he defines other zone coverages….

Cover 4 - is a 5 under / 2 deep (corner & free safety) against slot formations.
Cover 2 – is 2 deep (free and strong safety) 5 underneath
Cover 6 – is 3 deep 4 underneath with a weakside rotation
Cover 8 – is quarter halves matched (strong side plays quarters / weak side plays cover 2)
*cover 5 (man under 2 deep)
*leach – 4 under 2 deep where the star (nickel) is man-to-man on the slot receiver

Slot coverage variations:
Fist(c3)/Cover 4/slot (c1)/cora(c2)/switch(c2 corner over)/R (robber to 2 open)/thumbs(C3)/iowa (3on2bracket)

While exploring the defensive adaptations to offensive trends towards "the spread" (Va Tech in the 90s / Saban Cover 3 adjustments ), and not intending to repeat any of the fantastic coverage of TCU defensive tenets done at Run COD Hit, it would behoove us to at least go over how TCU would confront 2x2 / 3x1 formations out of their base split-field coverage, '2 read'.

TCU's 42 defense is based out of Cover 2 "Read", which is really just a robber + quarters read out of a MOFC look. TCU will typically not play ‘2 Read’ against any 1-back look (preferring Blue or Cover 5), so what we are presenting is just a ‘worse-case’ scenario against this coverage.

Since they are splitting the formation in half, they are just reducing the concept down to the 1, 2, or 3 receiver matching. Just like the Rip/Liz adjustment covered before, when facing a balanced 2x2 formation, the secondary would have to declare which side they are going to play as the 'read side' (where the FS will be robbing). If '2 Read' is called, versus a 2x1 formation, the FS would naturally rob the receiving strength (2 receiver side). With 2x2, you would have to declare "reading left" to communicate the 'read side' and the 'away side', alerting the away safety on how he will handle #2. To the 'read side', this is how zone distribution would essentially play out in a nutshell.

"2 Read" is the base coverage TCU bases out of (it really is just robber). They may not even run this coverage much after installation, but it remains the elementary foundation for all subsequent variations regularly employed.

To get down to brass tacks, the rules are relatively simple and outlined below:

"2 Read" is the base coverage TCU bases out of (it really is just robber). They may not even run this coverage much after installation, but it remains the elementary foundation for all subsequent variations regularly employed.

To get down to brass tacks, the rules are relatively simple and outlined below:

Read Left

• Read side Corner- 1x7 match deep vertical threat
• Strong (read) Safety - 5x1 force on run / pass read: open to flat "swing deep to 3"
• Free Safety- alley fit on run / pass use 'Robber rule' - vertical by #2 / no vertical by 2, rob curl-to-post of #1
• Strong Backer -match #2 - #3
• Weak Backer - match #2 weak vertical
• Weak (away) Safety -run force / pass curl-flat "swing deep to 2"
• Away side Corner-deep 1/2 (over post of #1)

Read Side Communication

Corner is 1x7 in press bail shuffle with a man-clue of the #1 receiver. Corners always 1x7 unless #1 receiver is outside of numbers (they never cross the numbers in robber). Corners always play inside leverage, always protecting the post (because you don’t know if you’re going to get help from the FS). The post-snap cushion is not enforced, and in fact, Patterson wants receivers to break the defender’s cushion so he’ll only have to play one side now. If there is only one receiver split, the corner will man-turn into the route. If there is more than one receiver split, he will zone-turn into the route. Because this is a robber concept, the corners are taught to make the post a priority and, if necessary, align as much as 4 yards inside the receiver to protect the middle of the defense. With these rules, Patterson essentially invites offenses to run the post-corner because he feels he can take everything else away and force this difficult throw. To get the most out of this coverage, a pattern-match communication system is utilized to hasten how the 3 key defenders respond. The corner will communicate pattern response to his area players (FS & read side safety). Of the read side calls he will make (and responses) are:

CHINA

If #1 is short/hitch the corner makes a “China” call. This flags man responsibility for the Strong (read) Safety. The read side safety will run under (to) #1 because the corner is sinking (on corner route) to match the first outside short threat (flat). A short #1 with a detached #2 receiver typically is going to give you a “smash” (or China) concept, with #2 continuing to press vertical. With #1 shallow, the corner will declare “China” and immediately look to match #2 over the top (and outside). The “China” call also help identifies that there is no post threat from #1 and that #2 is the only other possible threat vertical, so the Free Safety will look to aggressively jump the route of #2.

OUT

If #1 receiver breaks out (he’s no longer vertical) the corner will continue to sink and look to match #2. The ‘out’ call alerts the Strong (read) Safety to look to rob #1 underneath at 10 yards out. Since this overhang safety is always aggressively expanding to the flat, he won’t be giving up much separation on #1, so the throw (to #1) would have to be shallow and near the sideline for a completion.

IN

If the #1 receiver is not shallow (‘china’) but breaks inside at a depth greater than 8 yards (‘dig’ / ‘curl’) , the corner will communicate an “IN” call . This alerts the read safety that there is a threat coming inside over the top (of his drop). The safety should look to become an outside-in player (he’s going to the flat right now, because he’s got a curl player dropping - the FS).

Strong (Read) Safety

The (overhang) Safety aligns 5 yards deep on #2 (removed). Versus a standard tight end or pro look, he would align 3 yards deep and 7 yards widen (discouraging being reached on perimeter action). On EMOL high-hat pass read the target depth for his drop will be 8-10 yards. He is going to remain shallow on his drop with the intent to expand to the flat as quickly because the FS will be dropping inside of him in the curl (if that is what is threatened).

Don't get hung up on semantics - the 'read' safety "swing(ing) deep to 3" is essentially the standard 'curl-to-flat' responsibility, but an emphasis on staying shallow and man-conscious. This methodology helps the defender be less dogmatic and be an aggressive matcher in coverage ( if a man runs through his zone – he's got him vertical ). The rationale behind teaching it this way is to encourage the safety to open up and get to the flat (with no landmarks).

Free Safety

The alignment of the free safety will be 8-10 yards deep over the read side guard. This allows him to gain a clear read on an uncovered linemen and an quick response path to the inside vertical threat of #2.

Once the offense breaks the huddle, the free safety will identify the backs, determine the read side and communicate to the other defensive backs, “check 2 – read right” (coverage and what side is being matched). The response of the free safety is just like robber, with the #2 receiver as his pass key:

• #2 goes vertical, he matches all of #2 inside leverage.
• #2 does anything but vertical, he robs the curl/post of #1.

This vertical-clue will handle all routes deeper than 8 yards. If #2 is out (and under 8 yards), the free safety is communicating “WHEEL” to the corner (see the curl-flat combo illustrated above). This is essentially telling the corner, “you have an outside route by #2 - so you have curl-post help (from FS)”. This works even if #2 isn’t going to wheel that out route, but it lets the corner know he can now back off of #1 because of the help available.

When #2 is no longer vertical (out / out-up), the free safety then reads the hips of the #1 receiver. If #1 sinks his hips (for a break) the free safety will drive at the receiver’s break and step in front of him (interception point).

If the #1 receiver doesn’t sink his hips, the free safety immediately turns into the middle of the field (away from the receiver) to rob the post.

Inside linebackers
TCU's rules split-coverage rules mean they never have to displace the 6 in the box. The stacked (inside) backers would always match 2-to-3 regardless of formation with the other (away from final 3) being the rat in the hole. So if you’re a 4-2, its all relative if you play this with a 3-3; the numbers are the same. These players doesn't have to be anywhere fast, in fact, the slower they are at reacting the better, because they should be thinking draw or screen (off pass-action) initially.

For read side linebacker, once pass shows he is to middle drop vertical to find/match the final 3 receiver. This player is looking to defend his run gap first, then take away the hot (throw). By slow-playing pass action, he always tries to make #3 go over the top of him, and from there it just becomes a "man-to-man" zone as in basketball (boxing out #3 deep).

For the away side linebacker, it is essentially the same as the read side linebacker, with the exception of matching #2 (away) vertically. Typically, this player is the (wider) bubble backer and against any 1-back look, TCU will be slanting the defensive line. This linebacker must replace the former middle-of-the-field safety in the hole. Rather than a ‘robot’ reaction away from the ‘final 3’ player, he would gain depth vertically on #2. If #2 pressed vertically after 8 yards, the away side linebacker would have to carry him man-to-man regardless if he makes a break deep in his route. It isn’t pretty, but that is the answer for 1 back routes.

Weak (Away) Safety
On pass read, this player will play like a standard curl-to-flat player in cover 3. He has no immediate curl help and will work in tandem with the corner. He does not carry #2 deeper than 8 yards and does not reroute. He should never cross the hash when responding to an inside route, as the away side linebacker will be working to that area.

This is actually a great addition to standard robber coverage and the adjustment (with split-field) principle helps prepare your players for the ‘breakable’ scenarios. In the next (soon) installment, we will go over the very basic trips (3x1) adaptation using this same coverage.

This works great against most spread passing games and/or any type of even receiver formation (doubles/twins). As you can find in the playbook link below, "quarters" as it is called, provides a defense an aggressive safety-support run defense (because of a simple read for both safeties) as well as a fail-safe answer to two-man receiver game on the perimeter/vertical.
