DEFENDING TRIPS- DISGUISE AND SCHEME



In this post I will focus on defending the trips side of a 3x1 formation. There are certain considerations that need to be made when planning out a strategy for dealing with trips. Here is the good news, usually, defending 3x1 is much easier than defending 2x2 formations. The defenses that have trouble with 3x1 formations are usually defenses that prefer to play the game with balanced fronts/coverages (hence the discomfort with the overload that trips create) or don't understand that defending trips like anything else is a risk reward game. The defense cannot stop everything, every play. The goal is to have the defense in the best position to defend the most likely range of plays the offense can run in a particular situation. Lets look at some different options you can run towards trips.

1. A Cover 3 concept.
2. An X-out concept like Special
3. A Pattern-match coverage with a safety poaching #3 (solo)
4. The Classic: Straight up Man or Man-Free

Using these 4 options we can up with a plan for handling trips in a general strategy. I am not gonna get to much into the technique or scheme of each of these, the links provided offer that. The first thing to consider is disguise.

DISGUISE

Disguising coverage in football is done in 2 primary ways.

1. Stemming and Moving around constantly every play to the extent that the offense does not know what you are in pre-snap

2. Show the same look every-time and then stem to your coverage right before the snap.

Either approach can work, but I will discuss the 2nd because it will easier to explain, and in my opinion is easier to execute.

I like running 2-Solo, so I prefer to base my trips look out of that.

From this look you can stem and work into the other looks without much difficulty.

Lets look at the others.


Looking at these alignments it should be evident that there is not too much movement involved in the stemming of each.


Again these are simple examples, but even in their simplicity they can be difficult for the typical High School QB to read. The other disguise principal involves the movement of the SS. Since it is harder for the SS to align himself out of position, he can be the defenses most liberal person stemming. He can move around, show blitz, man, ect.

WHEN TO CALL WHAT

This comes down to game-planning. The generic rule is to understand the strengths and weaknesses of each coverage. Here is a simple list. It is not complete nor detailed, but sufficient to illustrate the point.


Ideally, the defense wants to be in a coverage that best defends what the offense is trying to do. If the defense expects run toward the trips, then 3-Mable or 2-Solo are best. If the defense is worried about middle and quick game, then cover 1 is the best bet. Finally, if the single WR is a concern, then special bracket is optimal.

No matter what trips coverages the defense has in its package, they need to be coordinated and planned. The best way to protect each one is to mix them up and have a sound disguise for them. This post was a simplistic look at disguising and calling different coverages to trips. If anyone has any questions about anything let me know in the comment section.

Defensive Fundamentals: Training the Eyes

In my post about "Pattern Reading vs Spot Dropping" I briefly talked about the importance of training a defenders eyes.


When making any type of "reads" in football, it all boils down to the eyes. There needs to be methodology to where a players eyes are supposed to be looking and how they respond to what they see. The more clear we can be with the progression of a players eyes, their ability to diagnose a situation, and trigger the appropriate response; the better we can all be at coaching defense.
Determining a progression for the eyes to follow coupled with a set of movements (responses) is the key to effective defensive football. All positions on defense can involve this principal. In this post, I will look at different positions and describe possible eye movements and progressions.

Why the Eyes?

The #1 mistake on defense is a player having his eyes in the wrong place. No matter how well a player is taught to shed blocks, break and intercept passes, or form tackle, it can all be for nothing if the players eyes are in the wrong place. The various techniques we teach to our players are intended to be used during a particular situation. Few techniques (like back pedal steps) are used on every play. The majority of these techniques are situational. What good is squeezing a down block on a pass play? Or dropping to the flat on a run play? Neither of these techniques would be good because they are inappropriate for the situation.

What tells a player the appropriate technique for a particular situation? Some type of visual cue. Players execute their techniques more effectively when they begin to make the connection of a visual cue with the desired technique to execute at a faster rate. The single most important point to training the eyes, is it will allow a player to execute their various techniques in the appropriate situations at a fast rate. This type of mental/physical conditioning process is what allows players to play fast, and the key to consistent execution come game time.

In this post, I will look at 3 different positions and describe possible eye movements and progressions.

1. Middle Field Coverage-Free Safety

Run: Alley Player Inside Out
Pass: Middle 1/3

I have discussed part of this technique already, but I will begin here with initial pre-snap eye keys. Player should align in the middle of the field and then get his eyes on the center or most visible offensive linemen. At the snap the FS should get into a backpedal and read the center for run/pass.

Eyes on Run Plays : If the linemen attacks aggressively forward, the safety should immediately get his eyes in the backfield to diagnose the direction of the run flow. Upon identifying the flow, he should Plant, point, and drive towards the ball carrier on an inside out path. On his pursuit he should keep his eyes on the ball carriers inside hip and maintain vision on a path that has the ball carrier inside and in front of him.

Eyes on Pass Plays: When the linemen key works backward (indicating a pass) The FS should maintain his backpedal and immediately get his eyes on the QB's non-throwing arm. He is looking for the long-arm of the QB. Upon Reading the long-arm the FS must intercept the pass with his eyes. This means he needs to locate the place on the field he needs to break to in order to make a play at the pass. Upon locating this position he should take a straight line to this spot. While in pursuit he should swivel his eye's from his aiming point back to the ball.

---- This is a simple progression of eyes that will keep the Safety in proper position. Must busts that the free safety makes will be one of two things. A. The player did not have his eyes on the proper place. B. A misread will prevent the player from executing the proper technique.

2. Press-Man-- Corner

After aligning properly inside, the corner will put his eyes on the inside hip of the WR. The corner is a dedicate pass player and will only play the run if #1 he FEELS the WR trying to block him (a good WR will run him off, so I don't plan for this too often) or he hears his FS or coach yell "Run, Run." Baring those non visual exceptions the corner will have eyes on the inside hip initially. He has 4 different techniques to execute in man coverage.

- Release
-Jam
-In-phase
-Out-of-Phase

The release phase begins with initial steps by the WR. During this phase the corner will use slide steps to move vertically and replace steps to move laterally. These steps are used to keep in the proper inside relationship with the WR. The corner is keying the hip because it is a true read for him. The WR's feet, chest, and head are all more misleading than the inside hip. What he is looking for from the hip, is for it to commit. When the hip commits the corner is now in the jam phase. When the hip commits it turns and breaks a 45 Degree barrier. Upon reading a commitment of the hip, the corner gets his eyes on the near number (pec) of the WR and jams it with his off hand while opening his hips. The opening of the hips and off-hand jam are designed to keep the corner on top of the WR.

For example, we will assume the WR releases outside. Once the initial jam is done, the corner must assess his position on the WR. Can he see the near number of the WR or not? If he can, he is in-phase, and his eyes will focus on the WR's eyes with his peripheral vision on the V of the WR's neck. If the WR's eyes turn to look for the ball, the corner turns to play the ball as well. If his eyes and V of the neck turn back, then the ball is under-thrown. The corner needs to basketball block the WR from coming to the ball while making a play on it himself.

If the corner cannot see the near number after the jam phase, then he is out of phase. His eyes will not leave the WR until the whistle. He will key the WR hands. If the hand move to catch the ball, then the corner will wait for a "1000-1" count then rake the WR's hands.

----------- Mistakes like opening the hips the wrong way, wrong hand on the jam, getting beat off the line, and allowing an easy catch are all problems that start with the eyes. Corners get beat inside on slants when their eyes migrate up to the WR's chest. Many catches are made when a corner is out-of phase with a WR and then peeks back to find the ball. These techniques are not very effective if the eyes are undisciplined.

3. Defensive end in a loose 5 technique

C-Gap Player
Technique: Squeeze on down-blocks, does not get reached, Spills the ball on pulling plays, Outside contain on pass.

After he aligns outside the offensive tackle the end will key the feet of the offensive linemen. He is trying to identify which foot the linemen will step with.

If the linemen steps with his inside foot, he is trying to down or scoop block another defender. Upon reading this the d-end should step laterally with his inside foot and squeeze the down-block. While squeezing down the line his eyes should peak down the line for any pulling lineman. If a pull is coming he must attack the inside shoulder of the linemen with his outside arm. If he does not see a puller, he gets his eyes on the backfield, he will take the running back on any read option.

If the linemen steps with his outside foot the end will step with his outside foot. He continue to read the feet for the second step. Is the lineman's feet working backward, toward, or around you. These cues will alert the end to what type of block he is facing. If the feet are working backward it is a pass block, this tells the end to get up-field and rush the passer. If the feet work toward him, he is getting a drive block, he must stay low and hold his ground. Now his eyes flash to the backfield to locate the ball carrier. He will remain in his C-Gap until the ball commits away from it. Finally, if the feet are working to get around him, he is facing a reach block. He must work his hips around the blocker and hold his gap integrity.

--------------Again eyes here are crucial. Defensive ends who run up-field on down-blocks are a major problem for 4 man fronts. This problem opens up huge running lanes for counters and options. This problem is a lack of focus with the eyes. When I see this on film, the d-end usually has his eyes on the backfield and can't see the down-block. Another error is a slow-pass rush. This is a problem that coaches who over-emphasize the need to attack the linemen. Some ends will be so focused on attacking the linemen that they take to long to recognize that it is a pass play. By the time he knows it the QB has had time to settle in the pocket and begin his throwing motion.

Conclusion

These are just 3 quick examples. Every position and technique in defensive football begins with reads. The key to good reads are the eyes. If you focus on the eyes of your players you will see a dramatic improvement. The eyes are the link that we have from reads to techniques. The better we are at coaching this process and emphasizing it to our players, the better our team's overall performances will be.

Cover Black- Inverted Man-Under Halves

Spread Teams put stress on the defense. The challenge of defending the pass and run effectively put the defense into difficult decisions. The need to stop the run while at the same time maintain excellent pass coverage is difficult. Zone coverage is the mainstay of choice vs the spread because of these needs. Zone allows all eyes to be on the run while coverage is developed to protect deep passes. Because of this, offenses attack defenses with quick/short, intermediate, and outside breaking routes. In response to this defenses have mixed in man coverage variations to deal with this attack.

Man coverage can take away short and inside breaking routes. Outside routes are harder to cover because of the inside-leverage defenders use in man coverage. In certain man coverages defenders can use outside-leverage. In order to use outside-leverage the defense needs to provide inside and/or deep support to remain sound. A popular coverage to use when the defense wants to defend the pass is man-under halves support.


In this coverage the players in man coverage will use a trail technique and the safeties will provide deep support. Any outside cut and intermediate inside cuts should be covered by the man defenders. However, there are two drawbacks to this coverage. First, the quick inside slants are hard to cover. The man defenders are out of position to cover these routes due to outside alignment and there isn't anyone that can provide immediate help to these routes. Second, run support is weak. The man defenders are too far from the action to provide adequate support and the safeties are gaining depth to provide deep pass support. This limits run support to 5 players. Given that the offense has 6 players to use in the running game, this puts the defense at a disadvantage versus the run. Due to these drawbacks the defense usually runs this coverage in long yardage situations where the threat of the slant and run is of less concern.

The does not put the defense in the best position, because the best coverage for deep to intermediate pass plays is restricted to long yardage downs. However, the offense can run these types of passes on any down. How can the defense improve this position? For one, the defense will need to utilize this coverage on situations other than long yardage. Another thing about today's spread offenses, is that they can check into different plays depending on what the defense gives them. This alignment will invite offenses to check into running plays.

The solution must then allow the defense to show this alignment but defend the run more effectively. If a defense can do this, then the offense will be in a guessing game. In short, the defense will have gained the upper hand. What type of coverage would this be? In comes Cover Black, an inverted man-under halves coverage.

COVER BLACK

Playing the Run

In cover black the defense shows the offense a man-under halves look and invites the run. The wrench in the works is that the defense has 7 players that it can commit to the run. The 2 extra run defenders are the safeties. The safeties need to stem to 1x8 alignment and flat-foot read thinking run 1st. On a run read the safeties can activate into the box quickly. Also, they will probably pursue freely because offenses do not account for the safeties in their run blocking schemes. This coverage is effective versus inside and outside running plays.

Versus the inside run

The linebacker is responsible for the A-gap. The FS sees the tackle move inside, so he move over to cover the QB pull. The WS sees the run action and activates to defend the B gap. The Defensive end leverages down the line and takes the back. If all goes as planned the QB will pull the ball not knowing that the FS will be in position to play him.

Versus the Option


Here the rules are little different. On fast flow the play side safety moves lateral and checks the slot receiver. If the slot releases towards him or vertical he needs to take away the play pass. The SS is man to man on the slot but begins with his eyes on the backfield. While jamming and disrupting the slot, he should trigger to run force whenever he sees fast-flow his way. The WS can protect the cutback by checking backside B-gap and then get into pursuit. The end can take QB.

Playing the Pass

The rules for the underneath man defenders are as follows.

1. Align o/s leverage on man
2. Maintain outside leverage and cover any outside cuts by your man
3. Stay over and outside your man on vertical releases.
4. If your man releases inside yell "in-in!" release him and continue to gain depth. (stay over the top in case he cuts vertical again. )
5. If you are covering a slot and your man is running a vertical route and you hear the corner make an "in" call, work inside your man. (You will not have post help anymore)

The biggest challenge is number 5. However, this is not a play type that people will run at a man under halves look.

Safety Pass Rules

1. Don't chase a shallow crosser. A shallow cross is a route that is below linebacker depth.
2. You have the 1st inside cut (past linebacker depth) of speed (don't take an inside cut by a TE).

Lets look at some diagrams of cover black in action.

Versus a Dig Post Combination

Basic rules application here. The SS makes his "in" call and gains depth. The corner should alert the SS to his inside cut so that he (the SS) can cutoff the route while the corner plays the route over the top. The FS will handle the dig.

Versus Vertical and Dig


This is an example where the SS will have to work inside his receiver. The corner will make an "in in" call. This alerts the SS that he has lost his post help, but will have outside from the corner. An important coaching point with this technique, is that the SS must work inside by going over the WR. He should be over and outside initially. It is problematic for him to work inside by going behind the WR, because if the WR cuts inside (ie Post) before the SS gets inside the WR will be wide open and have an easy lane to go the distance.


Versus the Deep Out by #1


The idea for the offense is to wall of the SS from getting underneath the out by #1. They run this when they expect the corner to bail and play deep zone. Versus man the route becomes more of a comeback. This coverage will look like zone to the WR's so they will try to wall with the slot.

Teams will not want to run a deep out to #1 versus this coverage, but lets talk about the technique to take this away.

The SS has to maintain outside leverage and remain over the top when the route pushes vertical. The FS should shuffle and look for inside cuts. The corner should stay outside and over, break aggressively outside as soon as the receiver breaks out. Due to leverage the corner is in perfect position to cover this route. The only difficulty will be if the QB throws the ball the WR's inside shoulder.

It is important for the SS to maintain proper leverage in this play, because he will be in perfect position to cover a corner route by the slot.



CONCLUSION


Cover Black is a great and deceptive coverage. It is a great change-up and stand alone coverage that can be run on any down. It is especially useful when your defense employs man-under halves. The offense will not be sure what coverage you are in when you align in this look. You can utilize man-under coverage on more than just long yardage situations when you have cover black as a change up.

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.
