On one hand it was freak plays against a freak offense. On the other hand it was a whole LOT of offense. On the other other hand Indiana is actually quite talented. On the other other other regression in pass rush. On the other other other they're consistently there to make plays. On the other other other other they consistently don't make those plays.

What is the essence of Michigan's 2013 defense, and how will it hold up against the remaining schedule?
Mathlete: For me, I see just one thing about this defense. They are a good defense. They are not a great defense, they are not a dominant defense, they are not a shut down defense, but definitely a good defense. They've had two awful halves (second half against Akron and second last weekend).
|They are a good defense. They will never be a great defense. They are a Thomas Gordon defense. [Upchurch]|
They've been put in some bad positions by the offense and haven't been able to bail them out a lot. But they haven't put the offense in a bad position yet this season. The only real deficits the offense has faced this year have come after defensive touchdowns or short fields induced by the offense.
I think Mattison has found the perfect positioning for the talent and the offense that Michigan has. Lacking real play makers he has put together a defense that has limited big plays against non-Indiana teams, forced teams to drive the field, convert third downs and go 10 plays without making a drive ending mistake. Most teams can't do that very times in a game. Nebraska, a healthy Northwestern and Ohio State probably can. Michigan State hasn't proven it can against an FBS team that isn't Indiana. Iowa may be able to, but probably not to a major degree. This works because this defense shouldn't be needed to win games. They aren't quite talented/experienced enough to do that without incurring major risk. Michigan's offense should be dynamic enough that a good defense forcing teams to beat them should get them to 9 wins, easily.
That's where the trouble came against Penn State, the offense didn't push the pedal enough and the defense wasn't quite good enough to push against the stacked deck. I am convinced that an offense that is aggressive, even with a few extra turnovers is the perfect compliment to this defense. We will struggle against the remaining opponents if that aggressiveness goes away because turnovers will still happen (that's football) but the defense is just not equipped yet to be the game-changing unit.

FORMATION NOTES: This is nothing out of the ordinary for Michigan, but who's up for a perfect overhead view of Michigan aligning in a 4-3 under?
There are your 6, 3, 1, and five techniques left to right across the front with Gordon hanging out in what I guess is an 8 or 9.
Michigan also showed over fronts, which they have to from time to time because Minnesota loves to flip its strength.
This did not result in a discernible uptick in effectiveness.
This is the Maryland I:
This is Michgian in old friend Okie Zero.
SUBSTITUTION NOTES: A lot more nose tackle in this one; Washington got more time than he did in any game to date this year with Pipkins rotating in regularly; once Pipkins went down Ash did get a few snaps late. Rest of the DL was generally Clark/Heitzman/Black with Ojemudia/Wormley/Henry backing up. Glasgow got a couple snaps before the end as well.
Usual rotation at LB was halted after Bolden made some errors, and then it was just the starters. Secondary was the usual except that Avery was the starter at CB and Taylor only came in for nickel packages.
[After THE JUMP: this is the drive that never ends.]

Brian forwarded me a mailbag question regarding where Michigan's defense is getting attacked through the air, i.e. are there certain coverage areas that have been particularly weak? It took me most of a day to chart every passing play; the resulting post is rather straightforward. Consider this your bye week from my logorrhea.
Data are here.
What I tracked:
1) Where the ball starts (hash or center). If the tackles lined up inside the hash it was "center"
2) Which zone it was thrown to, on a telephone keypad grid. 1, 4, and 7 are around the numbers to the sideline; 2, 5, and 8 are the area around the opposite hash to the wide side only, and 3, 6, and 9 are down the middle.
If a ball was on the line I always erred to the zone closest to the quarterback. This makes sense if you imagine a player covering Zone 6 will be responsible for carrying a player through that zone, and would be in better position to defend that pass than a guy over him.
3) Which side (strong or weak) of the defense. I noted "Strong" as wherever the SAM lined up in 4-3 sets and where Countess lined up in nickel sets. Once or twice this conflicted with the offense but it's better this way for identifying which players are being targeted.
Weakside/boundary players, usually: R.Taylor, Wilson, Ross/Bolden, Beyer (as WDE) on nickel, Clark on 4-3.
Strongside/field players, usually: Countess, C.Gordon, Beyer (as SAM) on 4-3, Clark on nickel, T.Gordon, Morgan/Bolden, Stribling/Hollowell/Lewis/Avery.
Sacks, throwaways, scrambles, and other such events that took the emphasis on coverage were excised. I couldn't reward those things which occurred because coverage was good enough to make them happen so keep that in mind as you read.
This space mentions all the time that in Mattison's defense the usual end/tackle distinction for the four guys on the defensive line is not a good representation of how similar or interchangeable those guys are. The nose stands alone; the SDE and 3TECH are kind of the same player, and the WDE and SAM are kind of the same player.
A primary reason for this is that Michigan runs a ton of defensive plays on which the SDE/3T and WDE/SAM switch roles. These are so common that they have a mascot around these parts: Slanty The Gecko, who was inexplicably the first Google hit for "line slant football" a ways back. This is another Slanty post.
I've covered this ground before, but to reiterate: a slant is an aggressive defense designed to get penetration as offensive linemen are surprised by the gap the defender tries to fill. This can lead to unblocked defenders—and big cutback lanes. Unless the offensive line makes the on-the-fly adjustment they lose a blocking angle at best, and then you've got a free hitter… as long as your linebackers understand what's going on in front of them and present themselves at the spot they should.
I'm revisiting this because the UConn game provided a look at what happens to the WDE when the playcall asks him to become the SAM. Both of these plays are Frank Clark-centric; as is often the case, this means one is good, one is bad.
The Good Part
First quarter, second and four on the UConn 29. they come out in four-wide. Michigan shows five in the box with linebackers over the slots.
That safety is a bit of a giveaway that Michigan will bring Beyer off the edge.
On the snap, Michigan does send Beyer; simultaneously UConn sends a slot guy in motion, threatening a jet sweep.
One of the primary goals with a slant is to confuse an offensive lineman expecting one assignment executing that either against air or a guy who he really can't block. Here that's going to be the right tackle. Henry, our last arrow to the bottom of the screen, is going to head outside immediately on the right guard; he needs to get upfield and be the force player.
Clark will "fold" back after taking a step past the line of scrimmage to get the right tackle to commit.
[After THE JUMP: it's like origami except someone gets buried at the end.]
FORMATION NOTES: Michigan alternated between their 4-3 with guys often split over the slots like so:
And their nickel package.
They also had some weird snaps where they would take their WDE and line him up like a SAM:
This was always a drop into man coverage on the TE by Clark. I did not call this out as a new formation. I probably will in the future.
SUBSTITUTION NOTES: Secondary saw Avery replace the youngsters as the third corner when Michigan was in nickel, which was quite frequently. The rest was Taylor/Countess/Gordon/Wilson as per usual.
At linebacker the usual rotation of Ross, Morgan, and Bolden. Beyer went the whole way at SAM, I think.
On the line, another light day for nose tackles. Both got some run but it was a lot of three-techs out there. Clark got the most run at WDE with Ojemudia backing up. Black was out there almost all the time; Henry and Wormley got more snaps than any other SDE/3T type with Heitzman also participating quite a bit. Glasgow and Godin appeared rarely, if at all.
[After THE JUMP! Points! Yards! None of those!]
FORMATION NOTES: Nothing weird. This one has pinched DTs, but they only did this once. This was in the first quarter, so you can see the three linebackers on the field:
In the second half they ditched a linebacker in favor of nickel packages (and probably tipped a stunt):
This is what I mean when I say pistol diamond: four guys in the backfield, hanging out and stuff.
SUBSTITUTION NOTES: Secondary was almost entirely Wilson/Gordon/Taylor/Countess with the nickelback usually Jourdan Lewis and occasionally Delonte Hollowell. I don't think I saw Stribling except on special teams.
At LB, it was the usual Bolden/Ross/Morgan rotation. Bolden had some issues and late it was just Ross/Morgan. SAM mostly didn't exist, but Beyer got the vast majority of those snaps if you include the nickel DE looks.
On the line, much rotation.Clark and Ojemudia rotated with a little bit of Charlton. Black was almost omnipresent. Wormley, Godin, and Heitzman all got significant amounts of playing time; Glasgow was marginalized in this game to make way for Willie Henry. The nose tackles played a bit but they were largely lifted in the nickel.
