Any of you football heads want to explain 2 gap scheme?

It is done primarily when the defense is expecting a pass play when the extra yard gives some momentum to a DT pass rush to help collapse the pocket.

The one yard is to give time for the defensive lineman to read the steps of the o-lineman. Its a read step. The 1 yard allows for the time to read it.
That is what makes this fun. Everyone does similar things for entirely different reasons!

 
The question isn't really whether the 2 gap will or will not work, it will work, but the way BP likes to play it leaves NU vulnerable to the run. He wants to be sound in pass defense and gives up some in the run. The problem is that right now the team is questioning itself too much and isn't sound in the run or pass because of it. He needs to make some changes that will allow the defense to use there athletic ability more and not worry so much if they are fit right into the scheme.

I think it has less to do with the way Pelini runs it and more to do with the players he has trying to execute it. Devnet posted an excellent conversation Charlie McBride had with Hail Varsity about the two-gap scheme. Basically, the scheme is brilliant when you have dominant tackles with great upper body strength that can control the line of scrimmage (a la Suh.) If you don't have that talent, you're asking less physically skilled players to be able to throw an offensive linemen one way or the other depending on which direction the play is going. At this point, I'd say it's abundantly clear someone like Thad Randle lacks that strength, and so do some of the younger guys at this point.

Interesting to note that we ran 1 gap versus SDSU.
And then we get comments from Pelini that with eight guys in the box we still couldn't make a play.

Personally, I think we all have to look beyond schematic changes at this point and question if we have the players to execute this or the coaching to put them in successful positions. We definitely have talent on this team and it's young, so that doesn't help. I really hope Pelini has some solution and I trust him to exhaust all possible answers, even if others lack that trust.

I think we have young, raw enough talent to at least just be average this year. They don't have to be great, just average. I hope the coaches can find the formula for that to happen.

 
Again, you can have the best schemes in the world, but if you dont play with fire in your eyes, you dont have a chance. Our guys have a serious mentality issue as a whole. Some guys play with that passion, but it comes and goes. It has to be there from all eleven on every single play. I dont know how we get it back, but there needs to be an attitude on D. There's just too much passive mindset right. This problem is moreso the issue than anything x's and o's.

Tackling. Stellar tackling would solve a lot of our defense's troubles as well, but tackling also requires an attitude. I dont see it. Havent really seen it at all in well over a year. Gotta get the back. If it's lost in coaching and teaching, then the coaches need to find a way to tap back into it and bring it to the top. Gotta get that fire back.

What does Michigan State run? They are number one in total defense this year, and were pretty good the last couple of years too.

They run a 4-3 Over Cover 4 most of the time. Though I think they also switch up to 4-3 Under at times and go man on the CB's and cover 2 zone on the Safeties.

Those schemes above are 1 gap.

For a list of teams that do run the 2gap system: Alabama runs 2 gap. Wisconsin runs the 2 gap quite a bit. Utah State runs the 2 gap. Hawaii runs the 2 gap. Texas A&M run some 2 gap. Washington plays 2-gap. Iowa runs 2 gap.

Something almost all of those teams have is at least 1 DT that is disruptive with massive strength. That's what the scheme needs.

Hail Varsity spoke with Charlie McBride and asked him about 2-gap. Here's the thoughts: http://hailvarsity.c...-talks-two-gap/
Do these teams also have two high safeties with only one LB in the box many times?
Most of them run a 3-4 base. It is a lot more common to run a two gap in a 3-4 (ie Steelers & Green Bay) I'm hoping this is a move down the road when we have the personal.

Bo Pelini at the teleconference comically(at least to me) dispelled the notion/perception that Nebraska runs a two-gap. He says it's not a two gap. We're not assigning guys to two gaps. That's it's a term that just gets thrown around alot (as I've said before). They just play real heavy in their gap control in some situations. They also play a lot of single gap/attack sets depending on the situation.

He also said that this year they've used more straight-up one gap scheme than any other year he's ever been a DC.

Not trying to "stick up for him" or anything, but it's just shows that no matter how much we sit here and speculate two gap/single gap, we really have no clue what theyre doing. I just found his comments kind of interesting.

I'm assuming this is asking about the question that is just above this post about LBs and safeties.

This is very important. The entire defensive scheme must work together. A large part of why we are getting slashed up by running is we don't have very many guys at the LOS defending the run. That was the success teams like Wyoming had when putting one RB in motion. It moved the other LB out to cover him. THEN, when the safeties are playing over the top, this leaves only one LB to cover anything that gets through the D line. That is NOT good. That makes it extremely easy to run block or simply get the RB to beat the LB to the gap.

Now, late in that Wyoming game, Nebraska made an adjustment on how they cover the RB in motion and it left another LB close to the LOS to cover the run and it helped.

The man in motion vs. Wyoming was the single back. When he went in motion, the MIKE went with him. In lots of cases Santos was atleast 5 steps behind. None the less, why would you not play cover two when the only RB goes in motion and they spread out 4 (motion makes 5) wide? That's an obvious pass situation. When that happened, it was obvious who the ball was going to. The RB because of the mismatch of RB vs. MIKE LB. Either that, or it was a quick pass to the opposite side of the motion. Either way, you don't risk a long pass when you are defending a 4 wide (5 with motion man) shotgun spread.

That happened sometimes but not all the time. Sometimes they started with two RBs and motioned one. That left the Mike as the only LB.

Gerry was the one, many times, that would chase the RB in motion all the way to the sidelines. They changed it up by having the DBs on that side change who they cover when the RB goes in motion. Meaning, if there were two WR on that side and the RB goes in motion to make it three, the outside DB would take the RB, the inside DB would take the outside WR and Gerry takes the slot receiver and covers him cheating to the inside so he can help with run support on that side.

What happens sometimes when the had one RB was that they cleared out the back field by putting the RB in motion. That would take the MIKE with him cleaning out the LB area. THEN, if all WR are covered, if the QB gets past the D linemen, it is wide open for 5-10 yards.

What has to happen in this situation (and I think they are started doing this) is you have to have enough BD type players on the field to cover everyone while still leaving the LB in the middle to cover the QB if he scrambles. Some would even say this is when the LB needs to blitz like crazy.

 
guys, when he asked for 'football heads', i think he was asking for:
