3 Keys To Controlling The Line Of Scrimmage

As a general rule, we like to be as simple as possible in our techniques and progressions when setting out to control the line of scrimmage.  We believe that repeatable processes that encompass nearly everything an offense can show us is vital to the success of our players.  Our drill work is repeated progressions stressing “Your technique will make you right.”  Furthermore, we believe that playing fast in a good call trumps playing tentatively in the perfect call.  There is a high amount of stress placed on physicality and effort pursuing the football on each and every play.  Watching the video and studying scouting reports are also critical pieces of defending your opponent’s run game.  We believe that these philosophies have led to our consistency and success on the defensive line.

Getting Aligned

In mixed downs, our alignment rules are generally stringent and uniform based on our call and the offensive formation.  We typically align with a 60/40 weight distribution with our covered hand down.  In our stance, we stress being comfortable and keeping their bodies aligned (feet, knees, shoulders, hands) toward their pre-snap alignment technique.  Their eyes should be focused on their man, or first threat, as we employ a man-to-ball key.

Our defensive ends’ pre-snap width is determined by the location of the running back. If the running back is aligned to our side, we get in what we call a “Trading Paint Alignment.”  This essentially means if we were to stand side by side with the offensive line, we would be close enough that our shoes would “trade paint” with the offensive lineman.  If the running back is aligned away from our side, we loosen up and width aligns for success. A running back in the pistol set would key both defensive ends to a “Trading Paint Alignment.”  For programs that like to stand their defensive ends up, we still use these general guidelines except we have gone away from the “near foot forward” thought process.  We have found our guys felt more comfortable having their covered foot back which would be exactly the same as if they were in their three or four-point stance.

Our defensive tackle’s alignment in our four down sets works to use any spacing the offensive line gives us with their pre-snap splits to our advantage.  Typically, we will align in the middle of the gap. Therefore, the only real difference between our 4i and 3 technique or G and shade would be which hand we have down or foot we have back in our stance.  Again, we are trying to use spacing to our advantage by not allowing either offensive lineman to have a leverage advantage pre-snap.

In our head up alignments, we look to split the cylinder of our first threat. Our post-snap assignment will key us into which hand we will have down.  For example, if we are playing a 6 technique and are responsible for the C-gap, we will play with our outside hand down.  This would be the same in our 4 technique and 2 technique assuming we are responsible for our adjacent, interior gap.  If our gap responsibility is determined by the flow of the offensive line post-snap, which is common for the nose guard in our three-down package, we will key the running back for our pre-snap stance.  We assume, until the offense proves differently, the side of the offset running back will be the backside of their run game and vice versa. Therefore, we align with our corresponding gap hand down based on whether we have the front or backside A-gap post-snap.  Pistol sets prove a little more difficult to determine without extensive film study and solid tendencies.  In a situation where there is no telling from the offense, we tell our nose guards to align in their most comfortable stance.

Block Recognition Progression

In a head-up or inside alignment where our pre-snap gap is determined, we base out of a four-step progression.  In an outside alignment, we base from a three-step progression.  Both of these progressions are all-encompassing of every type of run scheme our opponent can give us and can be tailored to your defensive coordinator’s run fit philosophies.

Our four-step progression generally applies to our 6, 7, 4i, 4, 2, G, and 0 techniques.  We believe in this progression due to the ability of the arc release in the various zone read and midline schemes that we see on a week to week basis.  The four-step progression plays out as follows:

Our first threat is the person we are aligned across from in our corresponding technique.  Our rule is “If he wants us, we want him.”  If our first threat does not want us, we do not want him and our eyes transition to the near hip of the interior defender.  If his hip is toward us, he becomes our new first threat, and we anchor our gap responsibility.  If his hip is away from us, our eyes transition to traffic.  Traffic encompasses any type of puller action back our way.  We frequently use the phrase “Check for traffic before you cross the street.” The street essentially stands for the heel line of the offense.  Since our eyes have naturally worked to the inside in our previous progression, we tell our defensive lineman to see front side to backside to the backfield in the scan. Whether your defensive coordinator spills, boxes, or splatters pullers are all determined by your individual run fits. If there is no traffic, our eyes have already worked their way to the backfield, and we are now able to slow play or feather the quarterback in their zone-read or option game.

Our three-step progression applies to our 9, 5, 3 and shade techniques. This progression eliminates step two of our four-step progression simply because we are either an edge player or are already aligned on our interior offensive lineman.  This progression is as follows:

These are executed exactly the same as the previous progression with the elimination of the second progression as we addressed above.

Again, these two progressions will cover anything an offense can run at you.  We have a saying around the office, “A shade is a shade and head up is head up no matter where you’re aligned.”  This simply reinforces to our players how completely encompassing these rules are when applied correctly.  There have been times in my career where we only three-step and two-step progressions due to us being an exclusive bend and chase team never reaching the quarterback mesh point.  There have also been times we have been exclusively spill, box, splatter, or a combination of the three.  That is the beauty of this progression.

Defeating Blocks On The Line Of Scrimmage

Now that we have discussed our alignment and block recognition progression, we can discuss how we defeat base, zone, and double team blocks.  We treat these blocks the same so this progression is largely encompassing as well.  This is also a three-step progression that is simply broken down into first, second, and third phase of the progression.

Our first phase begins execution at the snap of the football.  We strive to get our first two steps into the ground as quickly as possible knowing that contact will occur on the second step.  If we are in a shade, our eye landmark is on the “V” of the armpit.  We believe in this landmark simply because the body follows the eyes.  In the past, we had trouble with players ending up too thick on their first threat allowing them to get neutralized from their gap. This has greatly resolved that problem. Our eye landmark in our head up alignments is still the “V” of the neck.  Our hand placement in our shade alignment is the gap side shoulder and the gap side number.  In our head up alignment, our hand placement is on the cylinder.  Cylinder simply means both numbers.  Whether we are shaded or head up in our alignment, we always stress to strike immediately with the palms of our hands, our thumbs up, elbows in, and tying our hands together.  We grab cloth when we make contact with the offensive line.  As we strike, we stress keeping our body position and shoulder position square and level.  This helps ensure that we are re-establishing the line of scrimmage, not playing around blocks, or splashing off blocks.  Ideally, the culmination of the first phase should have us tight to our defender, in perfect hand placement, with the brow of our helmet in contact and level with the “V” of the armpit or “V” of the neck depending on our pre-snap alignment.

Our second phase begins with the extension of our arms in order to continue re-establishing the line of scrimmage and create spacing for our escape. As we extend, it is important that we also step vertically with our gap side foot.  This not only creates the power to remove the lineman from his spot, but it also slows or stops the lateral movement of the offensive line.  Ideally, our body position at the end of the second phase should be at a forty-five-degree angle with full arm extension on our first threat.  Our eye placement, hand location, and shoulder level should all stay the same through this process.  If our eyes transition to the backfield or ball carrier in this phase, we have a much higher likelihood of being moved from the line of scrimmage or, worse, being pancaked by our first threat.  Hand location fundamentals and shoulder levels will aid in the third phase when we work to post or shed our blocker.

The third phase for us can look one of two ways.  The first could be what we call a “Post” which is essentially locking out our first threat, at distance, with our near side hand keeping our gap side leg and arm free.  We execute this by re-squaring our body after stopping the momentum of the offensive lineman keeping our near hand posted on his gap side number.  After we have “Posted,” we stress heavy weight displacement on our inside foot in order to limit the drift caused by the offensive line trying to finish their blocks.  This body position restricts interior gap space while allowing us to transition to a flat pursuit angle if the ball does get into our gap.  The second way this phase could play out is a full escape progression.  With our hands still locked in our landmarks at extension, we execute what we call “Driving the Bus.”  “Driving the Bus” simply implies that our hand placement is similar to that on a steering wheel and offensive linemen are as big as busses.  Thus, the phrase “Driving the Bus” was born, or so I was told a long time ago.  Regardless of the origin, we execute a violent steering motion moving our inside hand down in conjunction with our outside hand up like turning a steering wheel. This action is why it is important to maintain level shoulders and hands so the player does not lose any of that range of motion in this violent action.  After we have “Driven the Bus,” our inside hand can now disengage the gap side number as it transitions into a rip or arm over movement.  Our outside hand will remain engaged until the rip or arm over is completed in conjunction with our inside foot now stepping through the space we created in our second phase when we worked to extension.  We tell our players they should be in balance and able to play in three dimensions after the completion of their shed.  Now that we have either posted or shed the block, our eyes can transition to the backfield or ball carrier.  The final depth of our defensive lineman whether they have posted or escaped is around one and a half yards behind the original line of scrimmage.  This allows for minimal vertical spacing, which we feel is just as dangerous as horizontal spacing on the line of scrimmage.

Although I did not specifically address the double team block, we attack it exactly the same way we would a one-on-one block.  We stress playing our first threat and that the second offensive lineman in this situation “Doesn’t exist in your world.”  We progress exactly the same way with the addition of the phrase “Step to skinny, rip to square.”  This means that when spacing is created by playing our first threat, we need to take advantage of that by stepping through to finalize our three-step progression.  Sometimes this space will never occur.  In that situation, we continue to engage our first threat knowing that we are restricting the climb of the combination block up to level two of the defense.

We hope this information provoked some thinking or validated a few coaching points that you or your staff has done in the past.  This progression really is as simple as we lay out in this article.  Again, we believe that simple, repeatable progressions allow our players the greatest opportunity for success.  We drill these things every day with the hope that it becomes muscle memory and reactionary rather than our young men having to analyze schemes or actions post-snap. We believe this has been the cornerstone for all our success on the defensive line.
