    Defensive Front Seven 101

    Alright, the season is over, and it's time to look to free agency and the draft to fix the myriad of problems confronting the Bills run defense.

    To begin with, when you have a conversation about position and need, it's important we're talking the same language. I've seen the phrase 1 and 3 technique, as well as the phrase 1 and 2 gap tossed around rather inaccurately on these forums, and think it's time to focus the discussion a little.

    As i always like to say, Football is not rocket science.

    To begin with, we will start with defining what football scouts/coaches/insiders mean with the word "technique" when discussing the front 7 (mostly the DL)

    1-Gap vs 2-Gap

    1-Gap: A defensive player with a 1-gap assignment is ideally a smaller faster player. His duty is to knife upfield, in an assigned gap, gain penitration, and disrupt the play in the backfield. The overwhelming requirement for a 1-gap player is speed and quickness, he is, ideally, not playing to absorb blockers.

    2-Gap: A defensive player with a 2-gap assignment is typically a larger, heavier and stronger defender. The 2-gap defender's job is to eat blockers, hold the line of scrimmage, wait for the ball carrier to commit to a side, and then react to the ball carrier's action. 3-4 defensive linemen and inside linebackers ( as well as their outside linebackers, depending on the scheme) are generally all 2-gap players.

    Technique refers to the position the defensive linemen (or, less commonly, linebacker) lines up, at the snap. The following picture highlights the positions (or gaps) the linemen can line up at.





    On the Techniques
    *note,I'll not cover all the positions for the sake of brevity. Most, due to the fact they are not base DL positions, rather situational ones.

    0 - This is the technique the "classic" 3-4 Nose Tackle plays. Some 4-3 Schemes, like the 46, use an "unbalanced" defensive line and prefer to line a DT up over the center in the zero, either slanted or shaded to a side. Typically, the slant or shaded 0 is a pass rush or 1-Gap Alignment. Any DT who plays Nose Tackle in the NFL has to be huge, typically the bigger the better. Most alignments which utilize the NT (excepting when slanted) call for the NT to play 2-gap.

    In the 4-3 the 0 technique MOST OF THE TIME is played by the Middle Linebacker with 2-gap responsibility. When the defense has a MLB playing the 0 technique, it will have a DT covering up the MLB with a 1 technique 2-Gap DT.

    1 - The "classic" 4-3 DT plays the 1 technique 2-gap, primarily. This is Tim Anderson's responsibility in the Bills' Tampa 2

    2 - The 2 technique is often the sole domain of the 3-4 MLB (both of them), it is a 2-gap position... (though some 'classic' balanced fronts for the 4-3 on passing downs will put it's DT's wide, and 1 gap them for a pass rush)

    3 - This is a popular technique depending on the front and scheme can be played by any number of positions. In the Tampa 2 (and many unbalanced 4-3 fronts), this technique is covered by a DT, who is a 1-Gap defender. The 3-4 in many of it's fronts will have it's DE's sit here in a 1-Gap to clog the inside run, in short yardage.

    5 - This is the most common technique played by 3-4 DEs, and "run stopping" 4-3 DE's in both unbalanced and balanced fronts. Trevor Pryce when he was on the Broncos was the best 5-technique player in pro football. Ideally, you want a 280-310 pound DE in the 5 technique, who can hold the point of attack. Depending on the scheme and abilities of the 5-technique DE, he will be called to play both 1 and 2 gap (though more 2 gap in the 3-4 and strong side 4-3 DE).

    7- This is the most common technique for the pass rushing end in the 4-3 (1-gap) in an unbalanced front, or a passing down.

    8- This is the most common technique for the 3-4 Strong Side Linebacker (2-Gap)


    In the base Tampa 2 the Bills like to run, the assignments for the DL are ideally the following.

    5/7/9 technique - Schobel
    3 technique - Tripplet, McCargo
    1 technique - Anderson
    5/7 technique - Kelsey/Denney


    How does all of this pertain to the Buffalo Bills?

    -The main problems the Bills had this year were not penetration from it's 1 gap defenders. The basic problems the Bills had this year, was our 1 technique tackle rarely deserved a double team, and even more rarely, could hold the point of attack.

    Without a 1 technique holding up a guard and center, the MLB cannot properly play his 0 technique, as his ability to cover his two gaps will be compromised by the fact he'll have to fight off blockers. When the center or guard is getting his hat on the MLB, most of the 4-3's run stopping ability is pretty much compromised.

    Compound this with the fact, the Bills don't have a single DE who can 2-gap from the 5 technique effectively, and our run defense will look like it did.

      because they compensate by putting the DE's wide, like outside the tackle to the side of the formation with no TE (the diagram shows two TE's although most offenses only use that set in short yardage situations).

      Great info- thanks.

        Re: Defensive Front Seven 101

        well, in the Tampa-2 the DE's are in the 7 technique on a LOT of downs.

        For a 7 technique, the general idea, is for the DE to get upfield in the "C" Gap, turning the play back inside to the MLB. The ideal, is the Tackle will be drawn away from the guard, creating an exploitable "b" gap for the 3 technique to hit.

        When the DE is in the 9 technique, it's a long yardage passing down

        The DE will play the 5 technique if the game plan calls for it (generally, against running teams), or on "running" downs.



        There are a few ways to exploit the Tampa 2 on the ground, the easiest is to line up balanced with two TEs, and force the DL to commit to a side, then run at the weak side. (same strategy works well against the 46, and other unbalanced line schemes in the 4-3)

        The other way, is to spread out, pulling the OLBs outside the tackles, and exploit the A or B-Gap with a pulling guard or FB.


        *note the graphic has 2 TEs for illustration purposes. If the Offense lines up with a TE on the right side, those "techniques" apply to the weak side, even without a TE on the line.

            well, if we're going to draft a DT to play 1 technique, we need someone who can 2 gap, with a large heavy body, who is not easy to move. Lots of teams are looking for those guys.

            I highly doubt we're going to draft Okoye (unless we think he'll make a good DE, and are looking for a good 5 technique end), as we have several DT's who can play the 3 technique, and that is NOT our overwhelming need at the moment (not to say our 3 technique tackles were great, just that they were not the weak link on the line).

                Re: Defensive Front Seven 101

                So would you at this point advocate going with a DE in Round 1 like Carriker, Anderson, Adams, Johnson, or Moses?

                Also is this the main reason why we got burned alot on outside runs last year? The fact that, Tim Anderson blows, and that we were severly lacking on the LDE side?

                Also where does Kyle Williams fit in?

                I got a ton of more questions, but I dont want to bog you down.

                  Yeah I am def. curious to know what you think will at the very least help.

                  I know your NOT an advocate of going DT round 1.

                    Re: Defensive Front Seven 101

                    You did a good job of explaining, but not every team uses the same terminology for "techniques."

                    In fact, most systems I've been a part of and/or have watched coaches go over their schemes at clinics, use a slightly different numbering system than what you show here.

                    In most systems, the even numbers are al of the "head-up" techniques:

                    2 is head-up on the OG
                    4 is head-up on the OT
                    6 is head up on the TE

                    And the odd numbers would be the shades.

                    This makes it a lot less confusing and a lot more communicable for players/coaches.

                    To compensate for the #'s out of order, we have what we call a "4i technique" (which stands for 4-inside) for inside the OT.

                    Also, you wouldn't have three "0-techniques." It would be "strong shade" or "weak shade."

                    And just to clarify, when lining up in a "technique," it refers to either head-up (as I stated), or the "inside eye" or "outside eye" of the OL in front of you. It's important to note that because it's a precise alignment, not just "that general area."

                    So, in the system I just described, a playbook of definitions would read like this for a DL:

                    0 - Head-up on the Center
                    Strong shade - Eye of the Center to the TE side
                    Weak Shade - Eye of the Center away from the TE side
                    1 - Inside eye of the OG
                    2 - Head-up on OG
                    3 - Outside eye of the OG
                    4i - Inside eye of the OT
                    4 - Head-up on OT
                    5 - Outside eye of the OT
                    7 - Inside eye of the TE
                    6 - Head-up the TE
                    9 - Outside eye of the TE

                    There is no "8-technique" using this system of terminology....unless, of course, there is an unbalanced line.

                    Not trying to steal your thunder, you did a good job. Just trying to help out, elaborate, and explain the difference in systems.

                      With that said, what do you think about Fletcher? The prevailing wisdom around here blames him for not making enough plays at the line of scrimmage. But sounds like you think our 1 techinique DTs compromised Fletcher's effectiveness as a run stopper.
                      Wake up, brush your teeth, and get ready for a day of hating the Dolphins. Or the Pats? How to choose?

                          What a refreshing thread ... it illustrates the large gap between those who know the game and those who claim they do.

                            ah. well that is a terminology difference there.

                            I have seen the slant/shade in place of the three 0 techniques... though i did make mention of them briefly in my original post. When you're slanting over center you're 1 gapping.

                            Never quite seen the 'heads up' 4, vs a simple five.

                            Nor do i remember hearing, playing the TE heads up being called a 6, though we both are calling the inside shoulder of the TE a '7 technique.' and the outside shoulder a 9 technique.

                            Seems the most significant variation are on the Tackle, where a 5 in your list would be a 1 gap outside the shoulder, and a 5 in mine would be a 2 gap heads up.

                            But then I've never been a defensive coordinator, so i am, by no means an expert on all the variances in terminology.

                              that's pretty much the case.

                              It's hard for the MLB in ANY 4-3 to be effective when you're getting a center, a guard, a pulling guard, Fullback, or combination of all four, getting a clean block on the MLB every single running play.

                              no DC would expect his MLB to be effective in that situation. I know as an OC, i loved it when we could get a clean hat to the 2nd lvl on the MLB, it opened up a LOT of the running game, and usually was the difference between a 2 or 3 yard gain and a 7-20 yard gain.

                              Watch Ray Lewis or Brian Urlacher. The games they dominate, they do not have anyone in their face (that's the way of the 4-3 Mike). The Super Bowl, however, the Colts had a FB, or Guard... or on many plays, even the Center, getting his hat clean on Urlacher, which took him right out of the Super Bowl. I think BU had 1 tackle for a loss, the whole game (though it might have been for no gain).

                              If we want to make due, with the DT's we have, the only other solution would be to get a prototypical Mike out of a 3-4 (6'4", 260), and plug him in the middle, so that he can have a chance to fight off the blocks reaching him. The problem is, finding a prototypical 3-4 mike, who can run well enough to allow us to play the tampa-2
                              My wife told me that if I had a dollar for every girl who found me unattractive, girls would find me VERY attractive.

                              MY WIFE SAID THAT!!!
