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.

Play Action Passes-Defending the Bootleg

I apologize for the return to the 60's hand drawn diagrams. Football season makes it hard to find enough time to write a post much less design the diagrams for it. I hope that the drawing do the job of illustrating my point.

Power running and pro-style offenses use play action passes to keep the defense off balance. One of the most difficult types of play-action passes to defend, is the bootleg. The bootleg puts pressure on the defense because it begins as a play that shows run action in one direction and then develops into a passing play attacking the defense the other direction. The bulk of the pressure comes from the offense forcing the defense to pursue one way and then have to quickly change direction and locate passing threats while simultaneously containing the quarterback. In this post I will explore defending the bootleg. First, I will explain the idea and concept of the bootleg. Then I will give a few examples of how to defend it out of cover 3 and quarters.

UNDERSTANDING THE BOOTLEG

To understand the bootleg, you must first understand the major reason that running teams use it.


#1 It punishes over-aggressive run play

The bootleg is an often used play, but derives it power the same way an infrequent trick play does. What are trick plays used for? For the most part it is not intended to "trick" the defense as much as it is designed to keep the D honest. For example, if the offenses is a big toss sweep team, they should have a toss pass in their game plan. This is important because it is needed to keep the corner and or safety from playing the toss too aggressively. If a toss team begins to notice that the corners and/or safety are playing the toss too aggressively, then they should run the toss pass. This is smart for two reason: First, it takes advantage of the opportunity to make a big time play. Second, it will take away the aggressiveness of the corner and/or safety, even if the ball falls incomplete. In effect the toss pass is the playbook to keep the defense honest. If the defense chooses to play the run over aggressively, then they will be punished by the bootleg pass.

#2 It utilizes 5 threats to attack the defense

The bootleg applies just like the toss pass, however defending it is more complicated then the toss pass. The toss pass involves one major threat and requires one player to defend it. On the other hand, the bootleg offers up to 6 threats. The more threats a play has, the more difficult it is to defend. This is the feature that makes the bootleg a great play. The majority of play action passes usually involve 4 threats. The bootleg usually has at least 5.


There are 5 Threats

1. Flat Route
2. Intermediate Route
3. Deep Route
4. Back Side Stretch route (post or dig)
5. Quarterback Run

* There is the 6th threat of the RB throwback, but I will not explore that option here, I classify that play as a trick play that punishes a defenses backside defenders for over pursuing.

The fifth threat is what separates the boot from other play-action passes. In normal play-action passes the QB sets up to read the defense, but in the bootleg he is rolling out away from flow and becomes a downhill running threat. If you are able to cover all the routes, you still have the threat of the quarterback run.

#3 It is simple to execute and change up

The boot is also easy for the offense to change up. They can run the same concept with the same reads, but be able to change up the routes. For example, they can run the boot strong and get the same look.


Not much has changed other then direction and the fact that TE runs a settle route. This route is still the intermediate read for the offense. The other 4 routes are present. The boot can be run from almost any formation as well.


Here the boot is happening out of double tight 1-back. Even though the TE (Y) and Z WR are running different routes (a push and post-corner), they are still attacking the flat and deep.


The boot can be extremely dangerous from overloaded formations like this. These sets force the defense to adjust on alignment and still maintain the ability to cover all 5 threats of the bootleg.

DEFENDING THE BOOTLEG

The first step in developing a sound defense for the bootleg is to develop rules and recognition points for bootleg strong and bootleg weak. These rules vary depending on the coverage called.

Cover 3 (Middle of the Field Coverage)

Rules for bootleg weak:

Play Side:

Flat defender----Gain Depth and break on the flat route
Corner-- Cover the deep route #3
Hook Defender---- Find and cover the drag#2
Free Safety------ Protect the middle field and eliminate the post#4

Back Side:

Flat Defender------ Check RB for throwback pass & get under the backside WR if he runs a dig#4
Corner---- Squeeze the Post to the FS #4
Hook Defender---- Become secondary contain on the QB. #5




The play side flat defender needs to gain depth and maintain leverage with the fullback attacking the flat. This is intended to allow the flat defender to help out on the intermediate route and be in a position to keep the flat route to a minimal gain. By gaining depth the flat defender give the QB the immediate read to throw the flat route. At times the hook defender can be sucked up on the run and have trouble getting to the drag.

Defending the strong side boot is very similar to the weak side boot.

Rules for Strong Side Boot


Play Side:

Flat defender----Gain Depth and break up on flat route #1
Corner-- Cover the deep route #3
Hook Defender---- Find and cover the settle route #2
Free Safety------ Protect the middle field and eliminate the post#4

Back Side:

Flat Defender------ Check RB for throwback pass
& get under the backside WR if he runs a dig#4
Corner---- Squeeze the Post to the FS #4
Hook Defender---- Become secondary contain on the QB. #5


The difficulty with the strong side boot is the settle route. The SS is put in a bind. If he is used to help on the settle route, the full back will be open and in a position to gain a good amount because of the SS leverage. On the other hand if he jumps the flat route, the hook defender will have a difficult time jumping the settle route. The strong side boot operates similar to the "stick" concept. It is covered more effectively if the hook defender is aware of the route and sprints to it as soon as he reads strong side boot.

Quarters Coverage (Robber coverage to the passing strength)

Rules for bootleg weak:

Play Side:

Flat defender----Pick up flat route #1
Corner-- Cover the deep route #3
Hook Defender---- Find and get under the drag#2
Free Safety------ Jump on top of the drag #2

Back Side:

Flat Defender------ Check RB for throwback pass
& get under the backside WR if he runs a dig#4
Corner---- Stay inside the post #4
Hook Defender---- Become secondary contain on the QB. #5



There is a trade off in this coverage versus Cover 3. Robber coverage allows the FS to play the intermidiate route aggressively, this is really the route the offense is looking to pick up a good chunk of yardage and/or first down with. By playing the FS on the intermidiate route, you can provide stronger coverage on the main two options that the QB wants to throw without relying on a linebacker that is caught in a run/pass conflict. However, the drawback is that the backside corner has to defend the post alone...... this is the most difficult route for the corner to defend. The one point of relief is that even if the post does come open, it is the last WR that the QB checks and the hardest throw to complete.

Rules for bootleg strong:

Play Side:

Flat defender----Pick up flat route #1
Corner-- Cover the deep route #3
Hook Defender---- Find and get under the Settle#2
Free Safety------ Jump on top of the Settle #2

Back Side:

Flat Defender------ Check RB for throwback pass
& get under the backside WR if he runs a dig#4
Corner---- Stay inside the post #4
Hook Defender---- Become secondary contain on the QB. #5



Again the same trade off as before. Quarters coverage allows the free safety to play the intermediate route aggressively at the expense of putting the corner 1 on 1 with the post.

Final Point

In my opinion, and you can take it for what its worth. I am more concerned with covering receivers than reading the QB on play action passes. Upon recognizing bootleg, I believe it is more important for the defenders to find and cover the threats they are assigned to cover, than dropping while reading the QB. Bootlegs are executed by finding windows, it doesn't matter if the window is behind(vertical) or beside(Horizontal) defenders. By finding and getting to the threats, the defenders will do a better job of eliminating horizontal and vertical windows.

SUMMARY

The key to stopping the bootleg is quick recognition, and clearly defined rules. Rules allow the players to know which receivers to pick up, and keep completions to a minimum. Even if they do get sucked up on the play fake, they will know which receiver they are looking for as soon as soon as they recognize pass. Any play-action pass puts pressure on the defense. Teams will use it constantly to punish defenses that are over-aggressive on the run.

Zone Coverage Technique-Reading the QB

In pure zone coverage techniques that involve reading the QB, there are benefits and drawbacks. to it. The benefit is the ability to see the ball and ultimately take advantage of poor throws. The drawbacks are the precense of windows the QB can hit, given the lack of sight on the WR's. I have gone into detail on this on a previous post. However, even the biggest proponents of pattern reading have certain coverages that involve players that read the QB. First, any coverage that involves corners that bail at the snap, do best to involve some type of QB read to gauge the type of pass (3 vs 5 step). Any Middle Field Coverage, involves a FS that stays in his zone in the middle of the field while he reads the QB for an indication to break.


Another drawback to reading the QB in pure zone techniques is the QB's ability to look off a defender and then throw the ball the other way. For example, in cover 3 the FS drops down the middle of the field reading the QB. The most difficult play for this player to cover is the 4 verticals (double seam). QB's are taught to look one way and give a pump fake to get the FS to break before throwing the ball to the other WR, that the FS can't recover on. This creates a problem. On one hand, you cannot tell the FS to break when he sees the ball leaves the QB's hand, this will be too slow more often than not. On the other hand, you can't give advice like "don't fall for the first fake" or the like. The worst thing you can do to a FS in MOF coverage is slow down his breaks. The effectiveness of the coverage relys upon the FS's ability to break on the ball well.


Is there another solution? Yes! The key is in finding a reliable key to read on the QB that indicates a throw is about to occur. This key needs to be present only when the QB is going to throw and not part of the pump fake. Reading the QB's eyes is not reliable in cover 3 for the FS, because he can be looked-off. Reading the ball is no good, because A, the pump fake can get you and B, waiting until the ball leaves his hand will be too slow.


The solution is to read the QB's non-throwing arm. Teaching the FS (or any other pure zone dropper) to read the long-arm is an effective technique. The FS should break when he sees the QB's arm go long (or lengthen). The typical QB does not pump-fake with his off arm extended. The only active arm in a pump fake is the throwing arm (unless the QB pump-fakes with both hands on the ball, still there is no long arm in this type of fake). The long-arm is the motion a QB makes when his off hand creates separation from his body. This separation happens in the beginning stages of a QB's throwing motion. Have you ever tried throwing the ball with your off hand stuck on your body? Try it sometime, it is pretty difficult. Have you ever tried pump-faking with your off arm extended, its possible but it will throw off your throwing rhythm. Most QB's do not have the adequate time nor patience to develop this type of pump fake.

Another benefit of reading the long-arm is the indication of where the ball is going. The further the off-arm is from pointing at you, the further you have to break, this lets the player somewhat know what angle he needs to break on the ball at. He does not have to wait to see the ball in the air to know what angle the ball will be going.


Some QB's show a clear extension of the arm. Look at Carson Palmer below:


Others might not be as obvious, but will still show an extension of the arm when beginning the throwing motion, even Peyton Manning:


Try this out and practice this with your players. I have integrated this into our cover three technique and seen tremendous results. QB's can no longer look us off and we have a breaking key that allows us to get in motion before the ball leaves the QB's hand. This read can be equally effective with underneath droppers and corners.
