3x1 Formations- Defending the Open Side

In my original post on Split-Safety coverage I outlined a simple system in the 4-2-5 for handling trips formations. The base adjustment is solo. This coverage locks the away side into solo coverage and allows the read side to defend the trips with a variety of options. This is the preferred way to defending the trips side of the formation. However, like any coverage, if you sit in it too long the offense will eventually attack the open side. Solo coverage is most vulnerable to the single receiver side. That is where special coverage comes into play.

Special is designed to create games and options on the single WR side. In this post, I will cover some of the coverage options that can be used have to defend routes to the single WR.

BRACKET

The first and most basic coverage to the open side would be "bracket." This coverage allows the WS to be in a position to aggressively force the ball on the run and take away the quick and intermediate routes of the #1 WR on pass plays.

The corner is man to man soft over #1. His rule is DGBD...Don't get beat deep. He has #1 and he needs to be able to defend the fade, post, corner, and skinny. The WS upon reading pass needs to work into a trail position on the WR. From this position he is man to man on any inside, outside, or stopping route by the WR. The linebacker will have the back man to man.

During the release phase the WS must work into a trail position. Versus a comeback route the WS should be in the proper position to take this route away.

Also, Versus a post, the WS and corner should have the WR on a high-low with no place for the QB to put the football.



TRAIL

Trail Coverage is the reverse of bracket. The corner will align outside and deny any outside releases by the WR. After the initial release the corner will work in a trail position, and is responsible for any quick, intermediate inside/outside cut bt the WR. The WS is soft man over #1 with DGBD responsibility.

This is a great change up and can easily be mistaken for solo coverage. This will be confusing to quarterbacks. Trail coverage on the dig route looks like this.

1/2's

The final option I will discuss will be simple 1/2's coverage. 1/2's coverages is a great change up on the open side. It changes up the run force to that side, allows the corner to sit and have interception chances, and keeps the backer from having to run with the running back to the flat. The only situation where the the backer would have the back man to man is on a deep release. I am not going to go into too much detail here, there is plenty of discussion and videos on playing halves coverage. Brophy especially has some good resources on running this coverage versus, multiple sets.

46 Defense- Cover 7

The 46 Defense designed by Buddy Ryan and evolved further through the work of current Jets Head Coach Rex contains many concepts that could be incorporated into different schemes. I know many coaches still operate for the most part out of a 1-High Middle of the Field Coverage look. In this shell the main coverages are 3-deep zone and man free. There are some things you can do, like roll the secondary into 2-deep coverage, but most people in “1-high looks” prefer to play 1-high coverage.

Buddy Ryan utilized multiple coverages in his 46 package. In addition to basic cover 3 and man-free, he integrated a number of rotation coverages each with multiple variations. The coverage I will be discussing today is “Cover-7” which is a (man-under halves) weak-side rotation coverage.


Base Rules



Coverage on the Wide-outs

The WS rolls to the weak ½ while the strong-side corner plays “thumbs” technique that involves him opening to the other ½. The other part of the thumbs is the jack backer getting underneath #1 and playing an inside-trail technique on the receiver. His job is to cover the inside cuts (and provide solid support on outside cuts) forcing the ball deep and outside to the deep corner.

Weak Corner and WS can play different games on the #1 WR. The options for them are:

  1. Fist
  2. Slice
  3. Fist/Slice

Fist is basic inside trail bracket coverage. The Corner lets the receiver get ahead while he trails him 1 yard behind and 1 yard inside. His key here is the WR’s hips (or feet). He is responsible for underneath coverage of the WR. The WS plays over the top and is responsible for deep to deep-outside routes.

Slice is outside bracket. In Coach Ryan’s playbook slice technique is described: “The corner drives through any outside break, and the Safety drives through any inside break.” It is used as an automatic inside the 20 yard line.

Fist/Slice is an interesting adjustment. Is a unique bracket that works well against a slot WR (but good on a single WR). The corner forces the WR outside (same as fist) then crosses over him to a point 3 yards outside and even with the WR. This is a difficult read for the offense because the corner appears to be denying the inside breaks while inviting the outside breaks. However, after the initial jam, the corner works to take away any outside breaks. This is a great adjustment to teams whom like to run the “choice” route to the open side. The big question in this technique is how to properly defend inside cuts. Here the WS has inside cuts by #1. He should be aware of deep routes, but must play the inside breaks aggressively. The only problem with the aggressive play of the WS versus the inside breaks is the threat of the double move (i.e. Slant-go). The corner must help out with these situations. In Fist/Slice the corner must get over the top of #1 anytime he breaks inside to the WS. This is why the corner must play the WR outside and even, so he is in a position to get over the top of inside cuts. This technique allows the WS to play inside breaks very aggressively.


Coverage of the Middle 3


I have covered the bracket techniques used on the WR’s to each side. The remaining three eligible receivers require a coverage system. The Strong Safety, Mike, and Charlie have this responsibility. Their options are:

  1. Frank
  2. Zebra
  3. 3-Way

These coverages are varied techniques that alert the player for lock-man, 2-man combo, or 3-man combo responsibilities. Frank is very basic; the player has his assigned person in straight lock-man. There is no exchanging; you follow the receiver to the stands if he goes there. In the diagram below the SS has the slot man to man. There are times you can put the corner in Frank technique and allow the SS to play the brackets with the WS, but I will not discuss the variations here.

Zebra is a combo (banjo) coverage, this is common to most teams that run man coverage. In the above diagram the Charlie and Mike banjo the TE and back. Zebra is basically an alert for a possible 2/3 switch.

3-Way coverage is an alert for a 3-man exchange and more importantly a play action strong. On play-action the Charlie would have 1st man out, the SS would have the first crosser (the Mike would pass him off ), and the Mike would play the man in between the two.

Anytime the backers are not in 3-way, they must be aware of which of one is in Frank. Usually, if a player is in a frank technique, the other two are in zebra.


Adjustments


Like any coverage, there are going to be prepared adjustments for certain formations. Formations like wing-trips (12 personnel) create conflicts with the linebacker.


The Charlie and Mike are not in position to cover the 3 receivers. If the wing releases flat and the TE runs a corner, there are going to be problems. First, the Charlie would be responsible for the #2 WR (wing) but could easily get walled by the TE because of alignment. Second, the Mike will have difficulty getting underneath the TE. Besides checking to a different coverage, there needs to be more effective way of handling this Set.


The “I’m Out” Call


This call involves the Jack and Mike swapping responsibilities. The Jack now plays man with the Charlie and Strong Safety. He will now be in either frank, zebra, or 3-way. The Mike is now the player in “thumbs” playing inside-trail on the #1 WR. The full adjustment looks like this:

The drawback here is the positioning of the Mike in respect to the #1 WR. He has more distance to cover to get in proper trail relationship on #1. However, the defense is in a better position to leverage the routes of the middle three wide receivers. Even versus some problematic formations, this coverage can involve simple adjustments and remain sound.


Situations to Check out of Cover-7


Cover-7 is used to aggressively attack and take away underneath routes. It is most effective against 1 receiver to each side and a combination of the other 3 players in running-back or TE alignments. As a basic rule of thumb, cover 7 can be run whenever 3 eligible receivers are aligned in close proximity to the core of the formation and there is a wide receiver to each side. There is more to it than that, and spread formations/tight end trips/twins variations will take the 46 defense out of cover 7. The purpose of this coverage is to provide aggressive underneath coverage versus sets with a wide-out to each side.


Summary


Cover-7 is nothing new to football. Coach Ryan ran this coverage in the 1980’s. This era was dominated by running formations. Despite the fact that spread formations were not as big an issue, Ryan found a way to get his defense into a 2-High coverage from a 1-High shell. In addition to just getting into the coverage, he crafted a simple and effective way to change up the way he did his rotation coverage. This illustrates a timeless principal. For every coverage concept you have, it helps to have simple and alternative ways of running it. If you are a cover 3 person, it helps to change up which players have flats, Curls, and middle thirds. The 4-spoke, 3 deep rotation coverage are examples of this.

No matter the types of formations you see, you will always have to disguise and confuse the offense. Cover-7 is a great change up coverage that can be easily run out of a run-stopping front like the 46.
