FORMATION NOTES: Michigan spent every snap in their nickel. This was fairly typical.
That also shows what I called "shotgun triangle" for IU. Wynn is lined up in the backfield behind the QB, but it's shotgun depth, not pistol. Wynn would always motion out after a hand-wave from the QB; this was always a decoy.
Michigan did show a few okie packages. This is Okie two; I designate them by the number of safeties.
SUBSTITUTION NOTES: Boatloads. Avery went back to safety and spotted Gordon and Wilson from time to time. This led to a lot of Stribling and Lewis, as Michigan played every snap in their nickel. Countess and Taylor did not leave the field, IIRC.
At linebacker the usual Ross/Morgan/Bolden rotation saw Ben Gedeon join. The line was the usual profusion of bodies. Clark or Ojemudia was usually one end with one of Beyer/Ryan/CGordon the other. On the interior, Washington, Black, Wormley, Henry and Heitzman seemed to split snaps almost evenly. Glasgow also got in some.

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.
[After THE JUMP: it's fine, it's fine, it's fine… erp.]
Wot it sez up dere^. Despite the blowout nature we got a good look last Saturday at the various positions that Michigan will rotate this season. So I charted who was in at what spot for every play. The results (link to Google doc):
Here's your starting defense, with everybody in their base 4-3 under spots. I want to self-congratulate the MGoStaff for nailing the starting lineup in HTTV with the exception of free safety, since Avery, though out of the lineup, was nominally ahead of Wilson on the depth chart.
The corners lined up to the field or boundary; the line was usually aligned to the formation but then CMU usually aligned to the boundary anyway. The safeties were always lined up to the formation. They split who ended up the deeper guy; usually it was the field guy, and usually that was Wilson.
There was heavy rotation in the front four, an almost even three-man rotation in the linebackers, and the secondary stayed put until it was time to empty the bench. It was rotation, not platooning; guys would go in for a certain number of plays then come out. I charted 44 non-garbage (before 14:59 of the 3rd quarter) plays; rotations as follows:
