slanty the gecko
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.

wsg Slanty, the football-playing, jean-vested gecko who is inexplicably the first hit in Google images for "line slant football", or at least was a year ago.
One of my main concerns going into the season was what would happen to the short-yardage defense that Michigan was so good in a year ago without Mike Martin and RVB. Turning a third and short into a punt is 50% of a turnover, and Michigan could paper over a lot of deficiencies last year by telling Mike Martin to destroy some guys on third and one, thus allowing other guys to tackle.
Illinois disclaimers are in full effect—they can't do anything against anyone—but the Illini could do even less of anything against Michigan Saturday, and getting bombed on short yardage was a major part of that.
Michigan blew up Illinois short yardage with slants. Multiple times we saw this pattern:
- Michigan slants away from a power run.
- The playside end gets inside and upfield of the tackle or end trying to block down on him.
- The pulling guard bangs into the playside end.
- Linebackers profit.
Actually, Michigan doesn't so much "slant away" as show one defense and run another. When Michigan isn't running their base 4-3 under call they are inverting it by blitzing Ryan and moving everyone else over a gap.
Let's see it in action. /fishduck'd
It's fourth and one on the second and final Illini drive to make it past midfield, just before the half. Michigan has just stoned a power run by Riley O'Toole for a half yard to set up this opportunity. Illinois comes out in one of their standard sets, a pistol with two tight ends to one side of the line and twinned WRs.
Michigan is in an over this time since the strength is to the boundary, but Illinois will move a tight end over and not have an unbalanced strength on the line on the snap anyway so whatever.
This is what Michigan does:
They're essentially moving everyone over a a gap and dropping Ojemudia into a short zone. On run plays he "folds" which consists of backing off, keep an eye out for cutbacks, and allowing the linebackers to run to the frontside. If you're watching a replay and are wondering if Michigan's doing this gap-shift thing, the WDE backing off the LOS is a sure tip. If you watch for it, you will find it—Michigan runs this on upwards of 20% of downs.
On the snap, Ojemudia backs off and the line shoots down. Gordon, who is right behind Ojemudia in the above frame, has followed the TE across the field and now takes contain responsibility to the playside.
You can see the slant better from this angle:
Campbell is now attacking outside the left tackle, like he's a WDE. Roh and Ryan both shoot gaps to the inside. They get penetration, giving up an outside crease to do so.
Ryan gets under fast. He's essentially through clean, so the pulling G has no choice but to pick him off. Demens is already a yard off the LOS and charging as the handoff is made.
Now it's all about tackling.
Demens went inside out here as the back tried to go north and south on fourth and inches. That allows him to use the pile as help, and look at Desmond Morgan popping up to say hi/clean up any messes.
If you take a second look at this frame:
Note how Morgan is also clean and has stepped playside as the slant develops. He's still trying to check for any potential cutbacks and find the gap he's going to fill; he is available if the back makes Demens miss or threatens to power to the line.
[After THE JUMP: play it sort of again, Sam.]
In re: "who are you optioning?"
This is a weird formation, right? Lewan is eligible receiver, Kwiatkowski is not?
It's a little weird. Neither Lewan or Kwiatkowski are eligible in that formation. Lewan wears an ineligible number; Kwiatkowski is covered up by a receiver outside of him. I call these formations "unbalanced" when I talk about them.
They're not that weird, though. Teams do it to screw with the defense's alignment, test various things, etc. If the play ends up being a pass you've declared that you've only got four receivers, but since the tight end can pass block you're still playing 11 on 11.
Occasionally you'll see Michigan line up with two receivers on the line of scrimmage to the same side. This drives me nuts since the slot guy may as well not exist. This was more common under Rodriguez but IIRC Borges did do it a couple times last year. These are always runs, and usually short ones if the defense notices the alignment, which it seems like they always do.
Why do coaches do this? They're trying to mess up a defense's alignment keys and get easy yards. It's the same principle at work whenever a wide receiver lines up at fullback and motions out to the flank, or when a running back ends up lined up way on the outside.
Join our flaming crater!
What effect do you think the 'Bama game will have on recruiting? Much to my surprise many fans think neutral or positive.
I don't think it will have much, if any. Michigan's down to a couple of scholarships in the next class. By the time the 2014 kids start committing in numbers, Michigan will have played 12-13 additional games and the Alabama debacle will be a lot less relevant than it seems right now.
If it's going to hurt, it'll be with Derrick Green and LaQuon Treadwell. I don't think anyone was optimistic about Green after Auburn popped up even before Saturday; Treadwell is more of a mystery. We'll see.
In general, short-term results are not the be all and end-all in recruiting. See Charlie Weis, Ron Zook, etc. You either have it until such point as your job is under threat or you're at Kansas, or you don't.
An update on the Stubhub thing.
Just a quick heads up that UM still appears to have their relationship in place with StubHub. I received an email on Friday from the Michigan Ticket Office proclaiming, “Don't forget to use our online Marketplace (in its second successful year in service) to easily resell your tickets electronically.” I know you mused about whether this relationship was still in place after StubHub referred to UM as a former partner, so I wanted to pass along.
False alarm. Still amazed at that MBA who managed to make counterfeit tickets incredibly easy to manufacture unless you were selling through Stubhub. Probably laughing moooooohahahahaha right now in a lair somewhere.
Inversion. Also, this section sponsored by Slanty the Gecko, inexplicably the first hit in Google Images for "line slant football," or at least it was a year ago.
Steve Sharik, a former high school who you may remember posting some great diaries a couple years back, sent me an email about what happened to the defense; I responded with a question, and he answered. So let's put me in a yellow box:
It looks like Michigan is slanting the DL a lot to get their guys in gaps between the massive OL and set up an obvious cutback lane in which the LBs are supposed to be 2v1, but rarely do both of them get there. It's so consistent that it almost seems like I have to be wrong. I want the LBs to absolutely tear ass for the gap behind the slanting DT (usually they leave the DE to contain the backside). Instead they check up for cutbacks constantly that seem like the DL's job. Am I crazy?
Slanting does two things to zone blocking:
- If I'm an OL zone blocking to the right, and the guy on my outside who I'm supposed to block goes left, there is a natural tendency to go after my guy.
- More importantly, slanting the DL gets penetration, which wreaks havoc on zone blocking.
Recall how effectively OSU slanted against us in 2007 (yes, that screen shot).
the most infamous
What would continually happen was the ball would show in a hole a LB was supposed to fill, which was done fine, but the hole was created so well that there essentially are two gaps where there was once one: there is space on both sides of the lead blocker, so the filling LB has to pick one, meaning the extra LB/S/C has to fill the other one. Consistently this second, unblocked defender was late and too far away, creating a seam in the run defense.
[ED: This came up last year too. I complained about Brandin Hawthorne not getting past a blocker against EMU. Michigan has been short on free hitters.]
BONUS: we also had a discussion on that seam route Alabama hit early and Floyd tackled immediately on. I am still in a yellow box.
Sharik: Even the normally reliable Kovacs was bad. Demens was in the wrong gap a few times, Morgan doesn't have a great feel for when to attack now or where to fit, and Kovacs and JT Floyd were very tentative. In other words, our extra run defender (when the QB is turning around and handing it off, they're playing 10 v. 11, so we should have an extra, unblocked defender vs. the run) was late to the party or in the wrong gap, creating the huge seams you saw. Even vs. the pass, on their conversion on a 3rd and long, Kovacs went to wide and too aggressively to re-route a seam, and ended up being outside the numbers and too close to the LOS, thereby giving up the seam right behind him.
I caught that Kovacs thing, but thought the problem there was a crappy chuck on the guy. If he really jams him there the blitz should have time to get there or Floyd has time to get over. yes/no?
Against the pass, the defender responsible for the seam must stay on that seam--reroute the receiver off the seam. You do this with both your horizontal and vertical position. When Kovacs was so aggressive he took himself outside of the seam and stayed too close to the LOS, creating an open window for the seam. The technique is to not gear up to hit the guy, but to shock, catch, and run. If a guy is running in the seam, it almost looks like man coverage if the defender is playing his technique correctly. (Actually it does look like man, the way to tell man or zone is by what other defenders are doing.) Also, Floyd can't come over b/c he has deep 1/3 and the outside receiver was running a go route.
If Kovacs stays in the seam window, he doesn't have to take his eyes off the QB and he can eliminate the possibility of a throw without touching the WR. And if their QB holds the ball b/c the seam isn't open, the blitz gets home (or at least has a better chance).
Actually, I think the designed route was an inside skinny; designed to be behind the Mike and in front of the Free. The WRs job is to clear the seam defender, then post to the middle at about 10-15. (Different coaches teach different depths, and different defenses command slightly different depths, as well as the drop of the QB--3, 5, 7 step.)
I am now out of a yellow box. When Steve mentioned that the slot defender on the seam often looks like man coverage, it made me think back to Courtney Avery consistently carrying receivers deep on similar routes, and wondering if that was what the intent was. We eventually figured it was—this was a BWS debate—and then last year Mattison flat out said so after Avery carried a seam route deep and Iowa got a 44-yard gain out of a simple crossing route; we asked what happened there and he said Countess got out of position.
Thanks to Steve for the input. Long way to go.
Picture Pages on a bye week? Sure. I generally take more snapshots than I can reasonably cram into one week of posting what with all the other whatnot that goes on in this space, so this is a perfect spot for some reheated leftovers.
Yesterday I tagged Whoever at WLB as one of the main trouble spots on the defense; last week I criticized the linebackers for a particular Edwin Baker run that popped big despite Michigan seemingly having it covered. I caught some criticism myself for not being harsh enough with Mike Martin on that particular play that I'm still not sure about.
In any case, I pick the individual plays after the game (or season) has developed enough for me to identify a trend, and I grabbed that specifically because of the WTF behavior of the linebackers. Here's a play from earlier in the season that got in my thought processes and may have compelled me to pull that baby out of the bathwater. Metaphors not guaranteed.
It's late against Eastern. The starters are still mostly in; the Eagles have been driving a bit. It's first and ten. They'll run a power play to the strong side of their formation*. Michigan is in their usual under.
*[People have told me this is a "Down G", not a Power O, because the guard blocks down—I see what you did there—and it's actually a frontside tackle pulling, along with the center.]
USUAL UNDER IS USUAL
Ryan to bottom of screen, Frank Clark to top.
The key guy to watch is Hawthorne, who is the topmost of the MLBs.
On the snap everything happens!
By this I mean three things.
- the center pulls
- the frontside tackle pulls
- Michigan slants away from the play
You can see the entire line headed inside away from the playside. Brink, Ryan, Martin: all are oblivious to the idea of containment. This is fine.
wsg Slanty, the football-playing, jean-vested gecko who is inexplicably the first hit in Google images for "line slant football."
Why do it? To get a free hitter. Your slant should make life difficult for anything run to its side. The downblocks are key in the power. They're the easy bit for the offense. If one gets beat your play is going to not work very well. In all likelihood your pullers are going to take defensive linemen in the backfield, leaving linebackers free to run up and smash face.
If the opponent runs away from your slant it should be okay because the linebackers know there's a slant on and can chase playside as soon as the offense gives any indication there is a playside. This gets the backside tackle/guard/whoever—the guy assigned to the WLB—blocking air. The WLB gets to scrape down the line to tackle.
This gets the backside tackle… guard… whoever…
…awww, come on, Hawthorne.
In the wider view you can see huge numbers of players on the backside:
Cutback == doom. Hawthorne has no responsibility but to get down the line to the POA. Note the difference in the disposition of the linebackers. Demens is hauling for the frontside; Hawthorne is in full block-catching mode.
Now, Michigan's D can bottle this up without needing a WLB if Ryan gets a two for one on these pullers. He's the guy currently inside of #68. The other puller is running right by him. He's already given up the bounce because of the slant; if he gets into the other blocker Demens has a free run.
Ryan doesn't. He gets knocked to the inside and pancaked, which erases backside help. The other puller gets out on Demens:
Demens has maintained outside leverage, forcing it back to his help, which is three yards downfield and getting farther away.
First down on a basic power run.
ITEMS OF INTEREST
Hesitation is a killer here and it does not seem explicable. Hawthorne does not quite know what he's doing yet, especially earlier in the season. The hesitation gets a little more explicable when you look at the previous play, when one Brandin Hawthorne got burned on a counter:
Even so, with the line slanting in front of him he should know to take off playside at any hint of a pull or any hint of a guy releasing to block him. Slanting should make LB decision processes easy.
This play is one of the archetypical examples of why the WLB is hard to block and can get away with being a slight fast guy… so don't get blocked.
This is especially bad for a player like Hawthorne. Hawthorne looks like Leo Messi out there. He has a hard time getting off blocks and has basically no chance if he's not thundering at whoever is coming out to block him. At least in that situation his momentum can pop the guy back and he can come off to tackle. He's done if he pulls the [REDACTED] Memorial Block Catching Dance.
Ryan missed an opportunity to MAKE PLAYS. The other thing a slant like this can do is take the playside DE/LB and make two guys block him. You see Ryan dive inside the first puller. This means the RB is going to bounce, which means Ryan's basically done. Also done is Ryan's blocker.
Ryan has one way to impact the play left: try to pick off that other puller, leaving Demens unimpeded on the edge. Here he takes the block and appears to try to fight back outside, which ends with him in a heap. This isn't the worst thing in the world but great defenses that swarm these kinds of plays with two guys get both the 2-for-1 and the WLB in the hole.
This is one of the reasons I'm looking owlishly at the WLB whenever something goes wrong. Picture Pages are attempts to thematically summarize trends I see as I'm UFRing, so when I pull a play to illustrate something it is a complaint/credit I've seen quite a bit of. That may mean I focus on the linebackers on a particular play that may or may not be Mike Martin's fault for not shedding his guy and tackling for loss.
Google images can be weird sometimes.
