At this point, we've covered the concepts of defensive gaps and techniques, and then we applied those concepts to the fundamental 4-3 defensive base formation: the 4-3 over. If you haven't read the first two chapters, I would advise you do so, given that we'll be using and comparing information from them in this post. Chapter One | Two.
The 4-3 Under
The 4-3 under formation has several similarities to its over counterpart, but also some stark differences that allow it to be more useful in certain situations. Let's start with what remains the same between the two.
Both packages have the same personnel. That is, both packages have two defensive tackles, two defensive ends, three stand-up linebackers, two cornerbacks, and two safeties. In both formations, the members of the secondary will line up in the same spot for a particular coverage. For example, in a cover-2, the corners will line up on the receivers and the safeties will each cover one half of the deep part of the defensive backfield.
The last similarity between the two formations comes with the weak side defensive end (weak vs. strong sides were covered in chapter two). With both the 4-3 over and under, the weak side end will line up in the 5-technique, just off the outside shoulder of the weak side offensive tackle.
Where the formations differ is when it comes to the linebackers, and remaining three defensive linemen.
For a quick recap of the 4-3 over, the 1-technique will line up on the weak side shoulder of the offensive center, the 3-technique will take the outside shoulder of the strong side offensive guard, and the strong side defensive end will take the outside shoulder of the outermost offensive linemen (either the offensive tackle, or the tight end).
The linebackers will line up according to the defensive linemen, with the 3-technique being an "anchor" of sorts. The WILL linebacker lines up behind the 3-technique, the MIKE goes inside the 1-technique (essentially straight on with the center), and the SAM gets behind the weak wide B gap.
We can throw all of that out when it comes to the 4-3 under alignments for our front seven (excluding the weak side end).
In the 4-3 under, the 3-technique will align to the outside shoulder of the weak side offensive guard, and the 1-technique will man the outside shoulder of the center. From here, the strong side defensive end will man the 5-technique position on the outside shoulder of the offensive right tackle.
This gives us the following defensive linemen alignments:
You may be asking yourself, what about the tight end? This is where we get the major difference between the over and under formations.
By now it should be fairly straight forward to recognize the gap assignments for each of the defensive linemen. The weak side end will contain the weak side C gap, the 3-technique has the weak side B gap, the 1-technique has the strong side A gap, and the strong side end will take the strong side C gap:
Given that there are seven gaps total, let's examine the gap responsibilities of the remaining members of the front seven.
We know that the WILL linebacker always follows the 3-technique. This means that whichever side of the formation the 3-technique is on, the WILL will be about five yards behind him. Looking at the image above, we can then see that the WILL is responsible for the weak side A gap.
We also know that the MIKE plays the middle assignment, between the WILL and SAM. Thus, our MIKE will line up just inside the strong side end, about five yards off the line of scrimmage. So which gap is he responsible for? Exactly; the strong side B gap.
Last, but not least, we have the alignment of the SAM linebacker. This is where things get shaken up the most.
Up to this point, we're used to the linebackers playing about five yards off the line of scrimmage. That's not the case with the SAM linebacker in the 4-3 under. Because of the shifted formation, we're actually going to line the SAM up in a two-point (no hand on the ground) stance, in the 7-technique alignment, just off the shoulder of the tight end. This results in the SAM retaining the strong side D gap assignment:
So you may be thinking, why put the SAM down on the line? He can just cover the D gap from five yards off the line, similar to his B gap responsibilities in the 4-3 over. Let's dive into that.
Why the shift?
Let's take the most obvious perspective first: the 4-3 under allows you to have another player on the line of scrimmage, which raises your odds of a negative or neutral gain on a run play.
If the SAM has less distance to travel, he will be able to get to the point of attack (where the ball carrier crosses the line of scrimmage) in less time. This is helpful when your SAM (like most SAMs) is a slower or sluggish mover, and won't get to his gap in time.
A similar reason for moving the SAM to the line of scrimmage is down and distance. If the offense only needs a yard (or less) to gain a first down, you want to move more players closer to the point of attack to minimize the distance they need to travel to make contact and prevent the conversion.
When they say football is a game of inches, they aren't kidding.
Finally, sometimes you may have a SAM who isn't necessarily the most athletic player moving in a direction, but is big, strong, and is able to hold up against a big, 6'3"+ tight end looking to mow him over. In this case, you like your odds of sticking the SAM on him for a run play.
You have to be careful here, though, because if you're playing man coverage and the offense runs a passing play, your less athletic SAM will potentially be tasked with covering a tight end, which may be a losing battle.
It's all about match-ups.
So which do I choose?
Over the course of a normal week in the fall, the team's coaches will review tape on the upcoming opponent. They scout strengths and weaknesses, plays the offense and defense will run, personnel changes, etc.
Another thing they'll look for, is what type of play a team likes to run from a particular personnel grouping. They'll look at what type of tight end the opposing team has, and whether they like the match-up with their SAM.
The formations used all depend on the offense's tendencies, the down and distance, SAM vs. TE matchup, and the type of SAM you've got. The coaches will figure all this into the game plan for a given week, and make the formation determination throughout the course of the game.
In next week's post, we're going to dive into the "Nickel" formation, some of the similarities and differences it has to the base 4-3, and situations in which you'll run it. This is perhaps the most commonly used pass coverage that teams employ today, so next week's post is very important towards understanding defensive schemes.
Terrance Williams Contract Creates 2018 Job Security
There's been a lot of talk about what the Dallas Cowboys will do at the receiver position this offseason. While there's a great divide on what the team should do with Dez Bryant, there's a fairly unanimous opinion that Dallas should find an upgrade over Terrance Williams. No matter where he ends up on the depth chart, though, Williams' contract should keep him on the roster in 2018.
Last offseason, Terrance signed a four-year, $17 million deal to stay in Dallas. Because we are now just in the second year of that deal, it is cost prohibitive against the salary cap to release or trade him.
Williams is scheduled to count $4.75 million against the 2018 cap. If Dallas were to cut him, it would accelerate his remaining guaranteed money and create $7.25 million in dead money this year. He would cost more against the cap off the roster than on it.
Even the June-1st provision doesn't help. Williams' dead money in 2018 drops to $4.75 million, which is a net zero against his existing cap hit. It would also push $2.5 million of dead money to 2019. There's no benefit there, and you lose an experienced player who knows your system.
If the Cowboys do like their WR depth enough to want to move on from Terrance, one option is to try to trade him. A trade would lower the cap penalty to $3.75 million and save $1 million. If he's traded after June 1st, it would save $3.5 million against this year's cap.
Of course, it takes two to tango in this scenario. Williams hasn't scored a touchdown since 2016 and has never proven he can take on a significant role in an offense. He was serviceable when Dez Bryant and Jason Witten commanded more attention, but he's a low-end WR2 at best and many teams likely wouldn't want him in their top 2-3 receivers.
Perhaps something could happen during training camps or preseason, when injuries may make other teams desperate. Then again, something could happen in Dallas that makes them less willing to part with Terrance.
As it stands, it seems unlikely that Terrance Williams won't be a Cowboy in 2018. And really, that's not bad thing.
Even if he gets pushed down the depth chart, Terrance would be a good insurance policy against injuries or any other issues that could happen between now and September. $4.75 million is more than you'd like to pay your fourth WR but it's a one-year problem.
If the Cowboys do add more WR talent this offseason, there is a trickle-down effect that strengthens the entire club. Williams, with his experience, is an upgrade over Brice Butler as the fourth receiver.
Therefore, unless circumstances both here and elsewhere allow Dallas to find a trade partner, Terrance Williams should be back next year.
Cowboys Trade for FB Jamize Olawale from Raiders
Less than a week after the Cowboys lost fullback Keith Smith to the Raiders in free agency, the two teams have worked out a trade to send FB Jamize Olawale from Oakland to Dallas.
Fullback trade! The #Raiders are sending FB Jamize Olawale to the #Cowboys, sources say. Dallas has its fullback, one who was with Oakland since 2012.
To facilitate the trade, the Cowboys will send their fifth-round pick (173rd overall) to the Raiders for their sixth-round pick (192nd), moving back just 19 spots.
In return, Dallas not only brings in a veteran replacement at FB but a player they already know.
Jamize Olawale was an undrafted rookie free agent of the Cowboys in 2012. Despite a strong showing in that preseason, Dallas did not have room for him on the roster. He was on the team's practice squad until December, when Oakland poached him.
Since then, Olawale has been a regular roleplayer in the Raiders' offense. He's missed just six games since 2013.
Jamize brings more offensive firepower to the FB position than Keith Smith had. He's scored at least one touchdown in each of the last three seasons. He can be effective both running and receiving.
Through the trade, Dallas picks up the final year of Olawale's current contract. It calls for a $1.5 million base salary in 2018.
Dallas Cowboys to Re-Sign Long Snapper L.P. Ladouceur for 2018
Continuity is the key to good special teams play in the NFL. Already losing long-time Special Teams Coordinator Rich Bisaccia to the Raiders - who promptly snatched ST aces Keith Smith and Kyle Wilber in free agency - the Dallas Cowboys have announced their intentions to re-sign Long Snapper L.P. Ladouceur for the 2018 season.
Returning on a one-year deal, the fan favorite Ladouceur will be back to do what he does best in cleanly executing almost every special teams snap for Chris Jones or Dan Bailey to handle.
Long snapper L.P. Ladouceur will re-sign with the Cowboys on Monday, according to sources, on a one-year deal. He will be in his 14th season with the franchise. Only Jason Witten, Ed "Too Tall" Jones, Bill Bates and Mark Tuinei will have more years of... https://t.co/yTQbMYyrIv
While Jones has improved as the Cowboys' punter with each passing season, Kicker Dan Bailey actually enters 2018 as another question mark on this unit. With the general belief around the team being that Bailey will be just fine moving forward, the Cowboys will no longer have to worry about who handles long snaps next year either.
L.P. Ladouceur is back in the silver and blue, and in this moment, everything can be alright with the world.
