Inside the Virginia Tech Defense

Virginia Tech’s defense is a unique one in major college football in that it is very much an older style of defense descended from the Gap 8 and Wide Tackle 6. When Frank Beamer coached under Bobby Ross, they ran the Wide Tackle 6, and he took that with him to VT. It is actually not a 4-3 base, as its introduced on your TV sets, but is a 4-4 front that has morphed into using 4-3 personnel. Most of the time, there is a safety/LB hybrid that is dropped into the box to create a true 8 man front. The reason why they can adapt to spread offenses reasonably well is because of the player they put at the hybrid position. It’s a different approach from VK’s 4-2-5, which dropped one SS into the box, but essentially a 4-2-5 plays like a 4-4 front against any pro-style 2-TE/1-2 back offense. How did you think TCU was able to defeat teams like Wisconsin with their 4-2-5?

However, what VT does is very different from TCU and here we’ll showcase the fronts and coverages VT likes the most. The primary reason why more teams don’t try to run this type of scheme is because of the inability to find the two swing players however, and you need them to play against spread teams.

VT’s version of defense is a morphed descendent of what the Washington Huskies ran in the 80s and early 90s when their defense dominated the Pacific coast under DC Jim Lambright. They made popular the "G" front and took the 1985 Bear’s 46 defensive front as a compliment, which Tech would call the "Tuff" package. 46 does not stand for 4 DL and 6 LBs, the name is derived from the player Buddy Ryan used to play one of the attacking LB positions. His number was 46. It is actually a base 4-4 front. The defensive front called "Bear" is part of the 46 defense, but they are separable things. A "Bear" front covers both OGs and the Center, making it an Odd front. A 46 is by definition a "Bear" front, but to use "Bear" does not necessarily mean a 46 defense. The "G" front is a 4-man Even front that covers both OGs with DTs, and is heavy on stunting. Because its Even, the Center is totally uncovered. So complimenting it with the Bear front gives you the choice of going Even or Odd with a stem (pre-snap shift). It is generally made with a 2i-technique on the weakside (Wide 6) and a 3-technique strongside (Split 6), so its quite close to the Over front (1 tech weak, 3-tech strong). The strongside End, called a "Stud", aligns over the inside of the TE (7 technique) and the other DE aligns in a 5-technique. VT shifts their G front to the Field side as well into a 4-3, whether its weak or strong, which gives them 3 fronts in the base package. This "Field G" is mostly what Virginia Tech is in nowadays.

Because of their Field/Boundary alignment philosophy, the same defenders do not always get matched on the same offensive players. Nuk Hopkins is usually a Boundary-side WR, so he gets the Boundary CB most of the time. However, if he goes Fieldside, he'd be matched on someone else. Watkins is usually Fieldside.

Vt_g_front_medium

The "G" front is the base front, but here I have not adjusted to the formation.

Because it’s a 4-4 defense that has to be able to handle the spread offense at times, it needs some rather special players at some of the hybrid LB spots. The WHIP LB is a weakside LB, analogous to a JACK LB in a 3-4, who often blitzes off the edge in pressure situations, but who has to be able to cover backs well. He does not have to be a big guy, but he does have to have a very high motor. He can have a SS build and sometimes aligns deeper, like the FS. You’ll see how they get away with that in coverage later.

Vt_tuff_medium

The 46 defensive front. Not adjusted to the offensive formation.

 

Field_g_medium

Field G front. Rover adjusts to the better receivers or Field side. Whip starts back and creeps up or vice versa.

The Rover is an OLB who plays more coverage, like a SS. Think DeAndre McDaniel. His initial alignment is quite often in the box, but he doesn’t get up on the LOS as much as the WHIP. Rover always goes to the side of the passing strength (not necessarily the TE side) or the Field side, and WHIP always aligns opposite the Rover. If the ball is on the hashmark, Rover goes Field side, WHIP to the boundary. WHIP often creeps up because he usually gets a 1 on 1 matchup with the RB in coverage.

Star-divide

Blitzing

There is an extensive blitz package in VT’s scheme. I don't have the time to cover them all, but this is a pressure-based defense. It is mostly combined with Man coverage and is pretty heavy on stunts and exchanges between the DL and LBs. Its heavy on blitzes from those two hybrid players. When they face 21/22/12 personnel, they’ll set up in the G front or Bear front most of the time. In that case, both Rover and WHIP will show blitzes naturally. This is particularly true when the Whip or Rover is aligned on a slot WR -- he’ll come hard on the blitz pretty often. If your slot recognizes it and runs a slant, the FS has to hustle to get there and take that away.

Vt_dog_inside_medium

Dog Inside Blitz, a common blitz you see from Tech.

Coverage

What VT plays most against pro-style teams is Inverted Cover 2 Robber, but the deep cover guys are the Cornerbacks, not the safeties. When they play 46 front, its mostly man/man, because it’s a pressure front like the Under we use.

2_robber_medium

Inverted Cover 2 Robber is a 2-deep, 5-underneath zone coverage that uses the FS as the Robber. WHIP might align himself like a FS, but he’ll come down over the middle into a hook zone instead of dropping for deep half-field coverage. The FS himself will play Robber over the very middle of the field and watches the eyes of the QB to take away intermediate routes, yet against the run he’s a 9th man in the area to fill a gap. Its a bit like a Tampa 2 defense, where the MLB drops back deeper in zone over the middle with 2 safeties behind, except that here you’re dropping the FS down instead of backing up the MLB. These coverages have the goal of taking away the crossing routes over the middle and the post route that is used to attack C2 defenses, but also keep a guy relatively close to the LOS to help with the run, or running QBs. I’d call both of them pseudo-Cover 3.

The Corners cheat deeper in this coverage at 7-9 yds, so they can rarely show Press man pre-snap when 2-Robber is the call. The pre-snap look is quite often Cover 4 because of this. They have to get depth immediately to play deep-half coverage. They are looking at the QB and reading his actions without letting the #1 outside WR get past. 

The Rover aligns to the passing strength pre-snap, so he’ll adjust to the slot WRs most of the time. His initial spot is 3x5 off the TE, reading the #2 receiver. Because he lines up so close to the LOS, he has to be really good with his backpedal fundamentals to be successful, but in 2-Robber he has the flat zone strong. Depending on the formation, Rover can pick up the #1 receiver short and the FS comes down on the slot, with the CB still in deep half-field coverage behind.Whip aligns himself several ways, so you need a good football player here. The most common is a walked out position on weakside slots, but he can also align deeper at 3x5 or almost as deep as the FS. In his walked out spot, he is reading the backfield triangle to the #2/#3 receiver and has the flat zone weak.

The other two LBs, MIKE and "Backer" play zones over the middle like any other Cover 2 zone. MIKE is the same type of player as MIKE in a 4-3 defense, but Backer is more like a SAM LB in a 4-3, and often gets the RB or TE to the passing strength. When the TE switches sides, usually the Backer flips spots with MIKE to cover him. Also, against Ace and Doubles sets, the coverage basically changes into 1/4-1/4-1/2 Cover 3.

So now the first question to come to mind is "How do they even handle spread teams when they can have 8 or 9 men in the box?"

If you play C2R, and the opposition sends the outside WRs deep, the CB must go with him, which takes away the deep help for everyone on one side of the defense, so that it basically ends up M2M. You cannot play straight M2M all the time.

Well, Bud had to change his defense a little to handle that. He had to use less of the C2R and more Cover 4. He had to make the Rover less a run-defender and more of a full-time DB, a SS in layman’s terms. Cover 4 is technically a zone defense, but plays like M2M and often ends up looking just like the normal Cover 2 you’re used to visualizing. Because of how it is designed, it is still strong with Safeties as run-gap fillers off the edges, but because of that they are susceptible to play-action moreso than a true C2 squad. Also, because of the rather shorter depth of the Safeties, you can attack their run reads directly with a vertical route directly at them, like a Post or Go route up the seam. What VT wants to do to you is show the 8 man front, and force you to go into max-protect blocking, and then peel those extra 2 guys back into Cover 4. That gives up some of the flat zone coverage, so watch for more WR screens this week if they show us C4.

 

Vt_c4_medium

To make that work, you still need to get pressure from the DL, and I think this has been one of VT’s biggest issues on defense over the last few years. The talent of their front just is not what it once was. Foster’s defense is always going to be well-coached, and being well-coached puts players where they need to be, but you still need some talent to beat better OLs even if the defenders are where they need to be. They just don’t have the special players they used to get at those hybrid spots and DE, which they always used to have.

Also when the offense sets into Trips, you're not able to play a true C4. It turns into a 1/4-1/4-1/2 scheme, C3, or you have to split the coverage so that the single receiver backside is getting man coverage. What I do see Tech doing is forcing opponents to keep the RB/TE in there to block by blitzing the WHIP often.

Trips_blitz_medium

Tech often checks out of 4 into their version of straight Man, called a Cover 6 package, but it maintains the C4 look. The 6 comes from the switches called between the LBs and the backfield. Backer and Rover would take the strongside back and pass him off inside or out depending on his route. If he went out, Rover has him. If he comes inside, Backer takes him. The same thing happens for Mike and Whip. With two CBs outside you basically have 6 ways it can work without changing the call. Cover 6 goes well with the pressure fronts they like to show.

Key point is the D-line

From all of this and everything else i’ve read about their D it relys heavily on their D-line getting some kind of rpessure on Boyd. If they can do that then their D will work to perfectin and we’ll struggle. However, Auburn and FSU have showed us that our O can stand up to a great set of DE and still give Boyd the time he needs. Also, the quickness in whcih we throw and snap the ball should keep them off od Tajh for the short passes we use a lot. Do you think they have the strength up front to beat our O-line?

Coverage on Dwayne Allen?

How is Foster’s D gonna scheme for him, while respecting Watkins? I would assume Hosyle (probably a huge spelling mistake on that one) is gonna cover Watkins early and often. Key point, if they bring the pressure how are they gonna cover Allen on a slant or in the flats?

by CurtisA88 on Sep 28, 2011 12:53 PM EDT reply actions  

Here..

If you haven’t read this, it plays directly into what you just said. They’re worried about the coverage on Dwayne.

He could be huge this game.

With the Field/Boundary theory

They really don’t play much direct assignment man to man, they put their best corner on the boundary side and their other corner on the field side with the FS and matchup whoever the offense sends their way. And based on this article Sammy lines up mostly field side (and pretty much all over the field anyway).. I would love to see Hosely focused that heavily on Sammy- because we use him as a decoy a lot as well..that would take one of their better defenders out of the play. But Hosely can’t cover everybody- there’s a lot of love to go around, I would enjoy watching Martavis go vertical a few times to keep them honest.

I dont think they can keep up with Allen M2M

They’ll have to play good zone coverage against him.

But the flats are the schematic weakness of the coverage they use.

3/4 verticals

I know Morris isn’t afraid to send 3 or 4 streaking down the field.. With the proper spacing this could cause problems..Those guys are well coached but there will be mismatches somewhere.

Dr. B, what do you consider the weakness of this D?

Or the weakest part, even if it is not very weak. Both from a schematic standpoint, and in conjunction with their players. I presume our offensive minds will be attacking that (hopefully.)

by Cristo on Sep 28, 2011 1:59 PM EDT reply actions  

Schematically, its the flats

Foster’s scheme basically tells you this: “I’m going to stop the run. I’m going to give you the flat and keep everything in front of me, but you better be able to block my blitzers because I’m sending them from everywhere.”

If you can give the QB time to throw and have guys who can make something happen in the flat, you can beat the scheme.

by DrB on Sep 28, 2011 6:24 PM EDT up reply actions  

Excellent Job Dr. B. Just what I wanted to read today. Thanks.

I think the OL is going to earn their stripes this week picking up blitzes. Dr. B, do you see their performance, as well as Tajh’s accuracy of course, as the key to the game this week?

If you’re Bud Foster I think it’s pretty simple. You bring a variety of blitzes and make Tajh take hits and throw under duress. I don’t see them sitting back in zone and waiting for us to pick them apart.

I’m cautiously optimistic but, I’ve just seen us wilt under their physicality in the 4 meetings under Bowden (8 yards rushing in 2007 with Davis and Spiller, really Tigers?). I’m about $%&#$% ready for all that to change.

My take on Foster's Gameplan

I think schematically we are an absolute nightmare matchup for Foster’s group. I think, especially being at home, that VT is going to bring a ton of pressure early and often. This way, Boyd, in his first road start, will have to deal with mutiple blitz packages and the crowd noise. I would expect them to really try and confuse Boyd. If he goes with this plan, we either go up big early and fall behind big early.

by Dumpster Troll on Sep 28, 2011 3:50 PM EDT reply actions  

I tend to agree with you.

I am no expert, but if their base has 8 in the box, then it seems that would be better for taking away the run, which they did in 2006 and 2007. That was our strength, and we had nothing once they shut down the running game. This year, I really do not think the running game is the strength. I think we are ok, but we have been more of a passing team so far. Don’t get me wrong, because I think Ellingtonis awesome, but if they sell out to take him out of the game, then Watkins, Nuk, Allen, Bryant, Brown, ect will kill them, provided Tajh can find the open man before they get to him.

by Tigerplowboy on Sep 28, 2011 4:10 PM EDT via mobile up reply actions  

Yeah... Our passing attack is too potent (and our running attack too weak) to justify 8 in the box. 4 in the box should be plenty from what I've seen. :-)

Bud either needs to focus on coverage or blitz/pressure. I don’t think they have enough horses in the secondary so it’ll be about pressuring Boyd. Should be an interesting chess match. We’ll learn a lot about both teams.

Wow, absolutely incredible breakdown on our D

I’m no expert but that sounds about right! Cant wait till Saturday
