Extended preview post of why Wormley and Henry are playing the positions they are, which includes the main reason. Full article can be found here.
Recently on MGoBlog, Brian wrote a piece previewing the defense as far as his expectations. In the past couple days, he's also discussed the Defensive Line and looked at the recently released Michigan depth chart. A question keeps arising, unknowingly getting answered, and then asked again. It's a common confusion, and an understandable one when looking at nomenclature of football.
In this post, I'm going to look at Michigan's DL and why Henry is playing 5-Tech (nominally, from now on called End) and Wormley is playing 3-Tech (nominally, from now on called Tackle).
What is Michigan Running?
I agree with Brian that this is a 4-3 Under. Michigan isn't going out there with a LOLB and a ROLB, and they aren't going out there and doing a lot of two gapping (though a 4-3 under will often two-gap somewhere). It's a 4-3 Under with a standup end sometimes. Furthermore, the defense will not consistently keep two guys in two-point stances and shift the DL every which way, like Wisconsin's one-gap 3-4.
This is a 4-3 Under all the way. Let's remind everyone of the gap assignments:
And let's take a look at what a nominal 4-3 Under looks like, the one most of you are familiar with from the early Mattison years.
Here, we're going to call the Weakside DE (WDE, 7-Tech) the Buck (it's Buck because "B" stands for Backer, like how MIKE is for Middle in middle LB), to keep with Durkin's terminology. He is, in fact, more DE than LB, but he will occasionally drop (see image below). The strongside DE (SDE, 5-Tech) we will simply call the End. The 3-Tech we are going to call a DT (or tackle). The 1-Tech we will call a NT (Nose).
This is close to what Michigan is running, but not quite. Actually, the image above is closer to what Michigan will now run than what Michigan nominally ran with Mattison as the DC. Notice how Beyer (the SAM LB at the top of the screen) is in a loose position. For Michigan fans, this is similar to how Greg Robinson deployed Stevie Brown in his 4-3 Under, when Stevie Brown managed to have a very good Senior year. This is what we call a "Loose" alignment, meaning he's 5-and-5 (5 yards off the LOS, 5 yards outside the offensive EMOL). Ross, the WILL in the picture above, is also playing a Loose technique (in this case, it is to allow the dropping DE to play an inside zone or spy and to allow the WILL to play the outside Flat Zone, where there is more likely to be an immediate threat in the pass game).
With Ross, an undersized SAM LB, Michigan will continue playing more of a 4-3 Under Loose.
Many 4-3 Under teams traditionally move the FS down into the box as the 8th man and rotate the SS to the center of the field. They do this because the Buck and DT generally protect the FS from having to face any wash, something the ILBs (WILL and MIKE) are more accustomed to. It'll look like this:
But Michigan won't be doing that as much this year. Instead, the SS (who always aligns to pass strength) will be the 8th man in the box. He can be inserted like this:
But more often he will align closer to this.
This essentially makes the SAM another ILB. He's protected a bit by the End, and the defense won't get out flanked because the SS holds the edge and the SAM can work over the top to provide additional support.
Wormley and Henry Primer
As a primer, Wormley is a guy that came in as a projected SDE. He was expected to be between 270 and 300 lbs. He has good straight line speed for his size and displays excellent burst when he's comfortable with what is in front of him. Unfortunately for him (and fortunately in some ways), he's also very long and tall. With hesitation sometimes coming when he has to take blocks from different angles, he often stands up. This leads to him struggling to handle doubles.
Henry on the other hand, was always a DT. He was projected as a slashing, penetrating 3-Tech that could also slide down and play the Nose if needed. He's more of a squaty player, but has the first step to beat OL to the spot he wants. This first step quickness gives him potential to be a two-gap player, and his squaty build also gives him the stout base to prevent him from getting clobbered when he's forced to choose one of two gaps. He also stands up too high at times, but has the strength to fight back against it.
Brian previewed these guys well in the DL articles linked above, and there is video there to demonstrate these traits in these players.
So Why The Position Switch
The Double Team
As I said, it's been explained, but never really answered. But the answer is quite obvious once it's pointed out. Wormley struggles more against doubles, and the 3-tech will almost never get doubled. The 5-tech will get doubled, possibly on about half the plays, especially with the way Michigan will align.
Notice the 3-tech isn't doubled on the run his direction.
This means that the 5-tech has to hold up to double teams quite often, it also means the 3-tech can simply be let loose to be a penetrating force on the interior. If you can get that out of your 3-tech, you cut off half the field and give the Buck a lot more options as a pass rusher, because he doesn't have to be as preoccupied with the rush.
Whether the SAM is in a Loose alignment or inside, initially, the 5-tech will often get doubled against zone based rushing attacks.
Here, the 3-tech is doubled, so he has to be able to handle that a bit, but the double likely doesn't last as long as the OL tries to get out to the WILL, and it is on the backside of the play.
Against man blocking schemes, he'll get doubled on essentially every strongside run (Power O and Counter F, for example)
He has to hold up at that position for the rush defense to have success. If he doesn't hold up, he gets washed into the ILB, and large creases in the defense form, particularly when the SAM is playing in a Loose alignmnet.
Again, if you want to read about the other main advantage to Henry lining up at End rather than 3-Tech, here's a link to a full post at my blog.
Grantland just published an awesome article about Pete Carroll and how he's used and adapted the 4-3 Under defense over the years. And, more specifically, how the hybrid versions of the scheme he's using with the Seahawks today have helped them adapt to the modern offenses and be as dominant as they have.
Note: It's a somewhat lengthy article, so save it for when you have a bit of time.
EDIT: Chris Brown of Smart Football wrote the article.
Over at Grantland Chris Brown of Smart Football has a great article on Vince Wilfork and the Patriots D.
The main focus on the article is how Belicheck makes his Hybrid 3-4/4-3 work. The biggest part of this article for Michigan fans is the part where Chris Brown explains the history of the formations and how we arrive at Michigan's 4-3 Under front. Especially since so many people think we're recruiting for a 3-4 (Guess what, we're NOT! http://mgoblog.com/content/mailbag-3-4-switch-again-kenpom-basketball-leaders-more-you-know, http://mgoblog.com/category/tags/last-time-we-are-not-switching-3-4)
this is good stuff. He explains the main differences between the techniques required in the 3-4 vs the 4-3. I tackle the (lack of) personnel differences between a 4-3 Under and a 3-4 here:
But here are the juciest bits from Chris Brown (the whole article is definitely worth a read):
These 4-3 and 3-4 teams typically differ in a key respect: which "technique" their defensive linemen use. Usually, teams must commit to one technique or the other, as each choice has all sorts of other implications for the defense.
And the first question for a defensive lineman is always, Am I playing a 2-gap technique or a 1-gap technique?
"Gap" refers to the area between offensive linemen. A 1-gap technique is just what it sounds like: The defensive lineman lines up in front of the gap he is responsible for and his job is to attack and control it. If nothing else, a defender must not allow a runner to go through his gap. While defensive linemen attack their gaps, the linebackers behind them are responsible for their own gaps. These are the defense's "run fits," meaning how they fit into an offense's blocking scheme to take away running space.
Pretty much we're going to run the 1-Gap 4-3 Under because it's a lot simpler to teach. 2-gap systems like the 3-4 are a lot harder to run. Just go read the article, it's great.
[Ed-S: Festivus Bump!]
In modern football, there are 2 popular base defensive sets. Most teams run either a 3-4 Base or a 4-3 Base.
The quick explanation of these defenses is that the first number (“3” in a 3-4) is your number of Down Linemen (literally people who line up with their hand on the ground in a 3 or 4 point stance on the line of scrimmage) and the second number (“4” in a 3-4) is your number of linebackers (people who line up in a 2 point stance, behind the down linemen).
This diary will discuss the 4-3 Under, its similarities to a 3-4 set, and make sense of our defensive line recruiting. For the purposes of this diary I’m ignoring the secondary. You need corners and safeties. They’re all similarly sized players, get fast ones. The front 7 is where you need guys over a 100lb range and some more major differences show up.
Here’s a base 4-3:
Here's a base 3-4:
Both of these defensive base sets have advantages and disadvantages, and both lend themselves to different styles of players. When it comes to what Michigan is running as a base defense, the 4-3 Under, recruiting starts to make sense if you look at it as a 3-4 defense.
The 4-3 Under:
First, look at the D Line from the middle out. In a 4-3 Under you have a defensive tackle on the Nose, in a 0 or 1 Technique (NT) (Technique definitions:
You then have 2 players lining up at the 3 tech (DT) and 5 tech (SDE). Then you have 2 players further out on the line, at a 7 tech (WDE) and 9 Tech (SAM). Finally, you have 2 linebackers off the line of scrimmage (MIKE and WILL).
Now, compare these positions to the 3-4 Base. You still have a huge space-eating Nose Tackle (NT) who lines up at the 0 or 1 tech, 2 Defensive Ends over the guards, tackles, or in between (4 tech... hmmm, just a slight shift from the 3 or 5 tech...) and 2 people outside of them near the line of Scrimmage (OLBs). Finally you have 2 linebackers off the line of scrimmage (MIKE and WILL).
If you look at these two defenses, the only main difference is one of your 3-4 OLBs has his hand on the ground. That’s it! There are minor shifts on the line and other intricacies, but big picture the 4-3 under has personnel requirements very similar to a 3-4.
For the 4-3 Under OR the 3-4 in your front 7 personnel you need:
- 3-Tech DT and SDE (5-Tech)
- WDE and SAM
Michigan is recruiting the right numbers for the scheme they run. These are 17-year-old guys we’re discussing with recruits. Some will get bigger, some are maxed out. Some of the WDE/SAM types will be better at coverage and will play SAM. We saw Frank Clark and Beyer make this switch this year, one was a LB, one a DE in High School, and they switched at Michigan. Some will be better pass rushers and will drop into coverage less at the WDE.
The “Glut” at SDE doesn’t exist since the 3-Tech DT is a very similar position in the 4-3 Under, so some of these guys will play there. The coaches know what they need to run the 4-3 under, and hopefully this diary provided some insight into the personnel requirements so we can somewhat understand the method to the madness.
= -5. But seriously folks...
I have been reading that it looks like the 3-3-5 is in fact the primary defense being used right now in practice. The D-Line will be Martin, Campbell, RVB, but right now Greg Banks is in Martin's spot. The Spur and Bandit are the Strong (Box) Safeties that will line up outside the D-line and closer to the line of scrimmage than the Linebackers. The Spur and Bandit spots are occupied by Kovacs and Mike Williams. Your MLB is still Ezeh, LOLB is Mouton, and ROLB is Roh. Woolfolk and JT Floyd are your CB's and Vlad is your FS (Cam Gordon is in his place right now)
I also wanted to put this topic in because it looks like the 4-3 Under is also being implemented with the same line-up, only Roh is the 4th D-lineman with his hand down and Mike Williams is the new SAM.
I think most of us on this board that were going back and forth about 4-2-5 and 3-3-5 changes with Roh putting his hand down, but it looks like instead it will be GERG's Under package.
I'm reading this year's Hail to the Victors magazine that Brian edited (excellent, as always) and trying to understand the terminology of the hybrid positions, but there seems to be inconsistency from site to site. In the magazine, Brian says that the spinner is the hybrid LB/DE, and that the term "quick" refers to the same position.
I've seen other sites and posts here referring to the LB/S position that Stevie Brown will play as the spinner, and the LB/DE as a separate position, the "quick", or preferably, the deathbacker. Anyone know what the terms officially mean?
