MSU Pass Defense
[Bumped, now that everyone's had a chance to wade through all the front page content from the weekend. Final MSU pass defense stats in 8 conference games: 268.5 yards/game, 59.8% Comp%, 7.6 yards/attempts, 22-3 TD-INT ratio. There's your first team all-Big Ten QB right there. Indictment of Dantonio/Narduzzi 4-3-or-bust defensive approach complete? -KJ]
As I am sure everyone knows, the defense has pretty much been in the epic fail category all year. I am going to talk about our scheme and Penn State's scheme. Why their defense works and ours costs us several games each year.
First, MSU prefers to run their base defense as Defensive Coordinator Pat Narducci has said earlier this year. MSU's choice for a base set is the 4-3 with a Cover 4. Penn State prefers to use the Cover 3.
MSU's Cover 4.
The Cover 4 uses the three linebackers to defend everything within 10 yards of the LOS. The OLBs take the flat, the MLB has responsibility for the middle. All four DBs drop deep.
The Cover 3
The Cover 3 also has the three LBs covering the short part of the field, but brings a safety up to take one of the flats. Only 3 defensive backs are left to cover deep. This gives the Cover 3 four players in zone coverage within 10 yards of the LOS.
In my preview of the Penn State game, I said "This makes it difficult to throw short passes, but a lot easier to go deep, assuming the QB has time" in reference to the Cover 3. The four players covering the short zones allows for smaller zones and tighter coverage between defenders. This makes it hard to throw the ball between 8 and 15 yards downfield. You have to attack the seems deep, 15+ yards downfield. The way to attack this defense is to get three WRs deep, which forces the safety in the middle to pick a side of the field, then you will have single coverage on the other side. For the offensive set shown, if the WR on the left runs up the sideline and the TE on the left runs up the field on the hash marks, the safety will have to shift over to the left side of the field to cover the TE. That would leave the WR on the right in single coverage with the CB.
Of course, in order for this to happen you have to give the QB time. This defense works really well for Penn State because their defensive line does not give opposing offenses time to let the WRs get deep. That forces other teams to either throw into the coverage in the 8-15 yard routes or throw it underneath on two yard routes.
Conversely, MSU's defense only has the three defenders covering the 8-15 yard routes. Additionally, the zones are large and the seems between them are exceptionally vulnerable. Purdue ran two consecutive plays that attacked the Cover 4 MSU runs, both were completed passes for 15 and 14 yards. For both plays, the ball is out in under two seconds. You can't expect to get much pressure from your d-line in under two seconds. The ball is always going to get out.
As you can see, this makes the MSU defense exceptionally vulnerable to basically all pases that are thrown within 15 yards of the LOS. That is something that the Cover 3 stops (or at least makes really hard to do), but the Cover 4 allows. As far as I am concerned, the Cover 4 is a prevent coverage. It should only be used if you have a big lead or are trying to force a team to put together a long drive or it is a 3rd and 15+. Outside of that, it is not a good coverage to use and Michigan State uses it all the time.
Addittionally, MSU always keeps 3 linebackers on the field. We do not substitute based on what the other team does, we only substitute based on the situation, ie on 3rd and long we'll go to a nickel package. That is why we get the defense set as shown below.
The OLB on the left has shifted out wide to cover the WR. It doesn't work in real life and it doesn't work in video games either. The outside WR runs a slant. The inside WR runs a flare(?) route towards the sideline.
The WR catches the ball and goes out of bounds after a 7 yard gain. Sound familiar?
This is the defense MSU continuously goes to. It is our bread and butter defense. It might work if we had 3 copies of Greg Jones at LB, but of course we do not. This is the defensive scheme that allowed Minnesota's bad offense to go for 500 yards, Purdue's offense to go for 500 yards, Central Michigan to go over 400, Notre Dame to get over 400, Wisconsin to go over 400, Michigan to put the game into OT, and Northwestern to nickel and dime us all day.
This is what Pat Narduzzi calls, this is what he likes, this is what he wants. This is why I want him fired. Promoted. Or Demoted. In any event, we need a new defensive coordinator if MSU is ever going to be better than a 6-6 mediocre Big Ten team.

Question
To play cover 4 as a standard defensive set does seem like borderline insanity. Its only advantage, as I understand it, is that the extra defensive back allows the safeties to play closer to the LoS so that you can more quickly get 8-9 men in the box to stop the run. But the way MSU plays it the safeties spread out wide pre-snap and back-pedal as soon as the ball is snapped, which only magnifies the gaps left between and in front of them. And besides, teams have figured out that they don’t even have to try to run at all (most pass attempts faced in the conference). The only other reason to play cover 4 is to disguise your real set (cover 2 man or zone, perhaps) until the snap. But, as we know, that’s a flavor other than vanilla and MSU don’t play dat.
My question is, though, why don’t we at least get the perceived benefit of the cover 4 – no big plays? Or defense is basically playing prevent most of the time and STILL getting burned deep. After the Purdue game we were 4th worst in the conference in pass plays given up of 15+ yards (also 4th worst in plays of 25+ yards) and I don’t think that’s going to get any better after the stats for yesterday’s game are included.
Extra DB?
What extra DB? Are you talking about having 4 DBs deep rather than 3? If so, I don’t think it helps the safeties get to the LOS for run support. They still have to cover the deep part of the field and if they get sucked up by a play action, it’ll be an easy pitch and catch for the QB. The safeties have to stay deep and that is why they normally make tackles about 8 yards downfield.
I think we don’t get the benefit of the Cover 4 preventing big plays is for a few reasons. The LBs are not fast enough to get to the edges. They are also not split wide at the start of the play. You will normally see MSU with two LBs in the box (like the picture right after the Youtube video. Two LBs in the box, one split out to be near the slot receiver). This forces the LBs to hustle towards the side of the field. This video of the Wisconsin game at the 2 minute mark is MSU in a Cover 4. http://www.youtube.com/watch?v=luyXTVQ4YRE 43 Gordon is towards the bottom of the screen and he turns and sprints to follow the WR, then has to switch as he sees the WR head upfield and out of his zone and he has to cover the other WR. He is not fast enough to cover the first WR, and then he has to stop and change direction to try to cover the second one. He is out of position to change direction because he was sprinting, so the two players he tried to cover on this play were both open. So our LBs go out there and are not really capable of covering anyone.
Also, MSU will switch up the coverage to a Cover 2 Man, or some other man coverage where the LB is responsible for either a slot receiver, TE or player out of the backfield. A lot of the time we get burned on wheel routes because our LBs can not keep up with whomever they were supposed to be covering. Gordon was beat by a HB in the CMU game for a TD, by Michael Floyd in the ND game for a TD. Misch was beat in the PSU game for a TD. The LBs were also burned in the Purdue game for a big gain by the FB. Brandon Denson was burned on the first play of the Minnesota game for a TD. So, basically our LBs were known to have issues covering since the second game of the year.
I hate to say it, I think it took me all year to figure out, but our safeties are not that good. They are slow to move over in deep coverage and seem to never be there to help prevent a big play. I really don’t think our safeties have made any plays in pass coverage this year. I can’t recall the name of the safety who graduated last year, but it looks like he was basically the key to MSU’s defense.
Lastly, I personally think it really hurts to not play bump and run defense with the CBs. Our opponents WRs get a clean burst off the line and this lets them get deep faster and to stay on their routes. The timing with the QB is not off at all.
I believe it also hurts that Narduzzi does not change personnel based on the offense. IE, if the offense goes to a 5 WR set like Notre Dame did, MSU staying in the base 4-3 defense. I think it would be a lot better to change to at least a 4-2 Nickel package. I think that is something that hrut MSU all year.
You're thinking of
Otis Wiley, SS from last year. He’s with the Lions practice squad(?) I think.
Light a man a fire, he'll stay warm for a day.
Light a man afire, he'll be warm for the rest of his life.
Wasn't Wiley hurt?
I recall he was out for UM and I think he was injured most of the season. Might be a leadership thing in the secondary.
Wow
I honestly never looked at the stats for MSU’s defense.
That is horrific. 22-3 TD-INT ratio. Wow.
Ha, seconded
What a standout statistic.
I was looking over the stats and going to post almost the identical short comment.
Something like:
22-3!
That’s horrendous!
Fuel to the Fire
In the All Big Ten Team, MSU’s starting CBs are given honorable mentions. I don’t think this is because they are bad and its a participation award. We were picked apart by the safeties and LB coverage.
I'm thinking...
…this would be a fine base defense to run in the Big 10 in 1999. It matched up pretty well with Iowa and was generally stout against the run all year. I can’t figure why that is schematically or anything, but it seems like we’re running a defense that matches up well best against the pro-style, power offenses that only three Big 10 teams run primarily anymore. And we don’t play ourselves. (OSU and PSU will still run it down your throat, but they’ll do it more from spread formations than MSU or Iowa will)
I’ve been a bit of a skeptic on the scheme being the problem, but those results speak for themselves. The only thing I still have a hard time reconciling is the difference between 2008 and 2009. I didn’t think Otis Wiley was THAT good, but it appears he was, along with the d-line getting more pressure (as far as I recall) in 2008. That and other teams had two years of tape of MSU’s defense to analyze.
I think this defensive scheme could be more effective, especially with better safeties and faster OLBs, but it seems bizarre to run a defense that’s not tailored to the majority of the opponents you’re playing, who run some version of a spread offense or at least use a lot of three wide receiver sets. I probably shouldn’t use this horrible hyperbole, but who do we know who stubbornly sticks to a scheme above else, even if he doesn’t have the players to run? It rhymes with SRod SMarrenelli.
One thing I don’t like in the post is the focus on Narduzzi. When a lot of your argument is that MSU’s basic scheme is flawed, I think you have to put that on Dantonio, especially when you’re talking about his specialty. Obviously we don’t know the division of labor on the MSU coaching staff, but the buck stops with Dantonio.
I generally don’t like the guy who calls the Huge Show and say the coaches are stupid. I really don’t get the people who think Don Treadwell is doing a bad job calling plays. But when you return seven starters from a pretty effective defense, along with a several others who got major playing time, you’d figure you’re going to have a pretty effective defense again. You might even write an offseason fan post talking about how the secondary should be a strength and how much better off we are than the bad old days. (I stand by that part, MSU’s DBs can’t have been worse than they were in the JLS-era) When that doesn’t happen, it seems reasonable to say what the hell is going on?
Technically, Yes, Dantonio is also at fault
I have not heard nor read about any problems/friction between Dantonio and Narduzzi. This leads me to believe they are both on the same page with this defense and it is what they want to run.
The reason I put the focus on Narduzzi is because changing a coordinator and keeping the head coach is better for the program’s stability. I like Dantonio and the work he has done, I think the team could improve under him by simply getting a new DC.
Schematic Match Up
Schematically, we do well against the run because we always play 3 LBs. LBs tackle better than CBs and are more prone to watch for/attack the run. Plus we always had 6 in the box even when teams went to 4WR sets. So we had the advantage of 6 vs 5. We basically dared teams to pass the ball.
With 3 LBs on the field at all times, that matches up well against Pro set teams. However, Minnesota is a pro set team, so Pro Set teams can still take advantage of the Cover 4.
It's even worse than it looks
I think there’s general agreement that the cover 4 makes you more likely to give up the short pass (under 15 yards) but is SUPPOSED to shut down the big play. The first part definitely held true. MSU faced more pass attempts (437 or 36+/gm) than any other team in the Big Ten and more than any other team in the country except Oklahoma State. On these plays they have given up a fairly ordinary 7.1 yards per attempt. But with the number of passes being thrown, this resulted in 3,019 yards given up, one of the worst figures in the country (116th out of 120 teams). So it’s safe to say that teams figured out that we were going to give up the short pass and, dammit, nothing was going to change our minds.
So did we shut down the big play? I think you can see where this is going. . . In 2009, MSU gave up 27 pass plays of 25 yards or more, again one of the worst figures in the country. Adding in passes of 15-25 yards you get 90 “big” plays given up (106th in the country) or 7.5/gm. Yow. That’s epic fail in anyone’s book, I think.
So although our run defense gave the appearance of being OK, the real story is that no one needed to run to beat us. Although the quality of our safety play was certainly questionable, I think you have to point at least one finger at the coaching staff here. If no adjustments are made all season after a glaring problem surfaces at least as early as week 3, then MSU is guilty of obstinacy in the face of reason, and not an admirable consistency.
Big Plays and Poor Defense
I remember when I played football and we called the cover 4 defense “mini prevent” because you were basically giving up quick outs, short drags, wheel routes, swing passes, etc in exchange for not getting beat for more than 10 yards per play. I’m sure teams like CMU still laughs when they think a defense like that can stop an offense that is actually oriented on the short passing game. Teams like USC and Fla can run a defense like a cover 4 because they have “all world” type OLBs who can actually cover guys out of the backfield, can actually attempt to cover some slot receivers, and can make plays on the edge. Our OLBs are terrible in pass coverage, and the results this year showed that.
What is a bit more concerning was the fact that we STILL gave up the big play in spite of playing a defense specifically designed to stop it. There are a few reasons for this, in an “order” of sorts:
1. Our DL play was generally weak on getting any kind of pressure with 4 guys. This resulted in QBs having all day to throw, unless…
2. We blitz one or two LBs most of the time to get some kind of pressure. Unfortunately, with a cover 4 or DBs “bailing out” to start the play this can…
3. Leave the middle of the field wide open from the D line to 15+ yards down field where the DBs are. This would normally not be too big of an issue (besides the constant 10 yard gains), except….
4. Our DBs take TERRIBLE angles on tackles and on thrown balls. Watching game footage shows missed tackles in the secondary, DBs allowing TEs and WRs to run right in front of them for catches, etc
Basically, a breakdown on every level. We just needed a different scheme and never got it. This is just coaching the talent you are given, and nothing more. The scheme needs to work with the players you are given, and our coaching staff refused to admit this for the entire season
"It's a trap!"
Blitzing
Whenever MSU blitzes, they are not in a Cover 4. The Cover 4 is a zone defense with no blitzers. If MSU sends a LB on a blitz, then that is a different defense.
MSU did zone blitz a lot this year, but normally the blitzes were done in man coverage.
Dr D
Cosign with everyone else, this bad a D leads to more questions than answers, even on our status on the Nard-Dog and Dantonio, 2008 vs 2009, players, etc etc. I don’t have anything to add here except to thank you for all the work this season. It was always illuminating, even if it was continually soul-crushing.
T-Shirts
I"m thinking we should have t-shirts made up with the 2009 MSU football schedule/results on them with the label “Soul Crushing Tour 2009.”

I'm thinking
If we take what Dantonio said going into the half against PSU out of context, it becomes a perfect quote about our defense:
Q: “What can we expect after halftime?”
A: “More touchdowns!”

The really soul crushing part
Is that this is the pinacle of MSU football. The team is not going to get better. If everyone else knows you are going to play a majority of your defense as a Cover 4, then they are going to game plan accordingly.
Sure the defensive line did not get much pressure, but with the QB getting the ball out in under two seconds, its hard to generate pressure. The games that kill me are Minnesota and Purdue. Those are bad ball clubs. Minnesota scored zero points twice this year. They scored 42 against MSU. That game was so much of an anomaly for their offense that you would think MSU had the defensive talent of a bad FCS team.
Even if MSU has big upgrades in talent, this defensive scheme is always going to cost the team wins. I am thinking this is why NW won in 2007. The spread offense was basically designed to kill this defense. Next year Michigan is going to have a Sophomore QB, is everyone looking forward to them putting 40+ points on the board?
This defense is 100% dependant on the other team making big mistakes. Dropped passes, bad passes, blown blocking assignments. Even a mediocre FBS team is not going to be that consistently bad for an entire game.
This is MSU football with Narduzzi. The team will probably range between 6 and 9 wins but never get better.
To accept the defense as is...
Is to say that they are putting out their best 11 defenders, which doesn’t say much for DB depth. But the real problem is, they were so stubborn in their sets that teams could figure out what they were doing defensively. When you see Cover 4, the LBs split out a lot wider than they do on a normal down. As Dr. Detroit noted earlier, when they shift to a 4-3 stack, they are blitzing; when they are in 4-3 under, they aren’t. If you’re going to do that, you might as well hold up a sign informing the QB of the set you’re in.
Not saying the base package can’t be done; Penn State runs a 4-3 most of the time, and has considerable success with it. The main reason it works there is because they rely on a Cover 3, their D-line gets pressure, and their zone blitz packages are exotic- you quite literally could see any five guys blitzing, with the rest dropping into zones. It’s really confusing for a QB to see three D-line guys backing off, with one LB, both safeties and a corner coming. Of course, if the QB’s prepared it’s an easy completion, but how do you get prepared for a zone blitz like that?
Actually, I think MSU had the personnel to run a 34 with Decker or someone playing as the extra LB. Teams like the Steelers run it because it gives them blitz/coverage flexibility, and they don’t have to show their hand too much. The best attribute of a good defense is unpredictability, and we didn’t have that all year. If we can’t disguise what we’re doing, it doesn’t much matter what we’re running. So, guys, a little unpredictability please?
Stack vs Under/Over
The 4-3 Stack was when MSU was not blitzing.
The 4-3 anything else was when they were blitzing.
Although towards the end of the year they got a little better about hiding blitzes out of the 4-3 stack.
Never seems
like state ever has a good pass defense. They have gotten better with the rush but all the years ive been watchin, they struggle with the pass

Narduzzi In the Press Box
Does anyone know when Pat moved to the press box?
At the start of the year he was on the field. Generally if the coach is moved from the field to the press box it is to improve the defense. IE he has a better view of what the offense is doing and can adjust accordingly.
So far as I know, he was only in the press box for the PSU game.
