4-3 vs. the Oregon Spread - LB / Nickel Play


Introduction

How you defend the Spread formation depends on what kind of Spread formation you are facing.  Some teams are better at throwing the ball than running the ball.  The Oregon Spread of 2010 is a more dangerous beast than earlier versions in that it can beat you both running the ball and passing the ball.  Still, the explosive Oregon run game is what opposing DCs must stop first.  Most 4-3 teams play Quarters coverage vs. the Oregon Spread to help to defend the run.

LBs like Quarters coverage because it allows them to run and play fast.  The safeties will be involved in run support and they will take care of the cutback, which allows the LBs to attack and play downhill.  The Quarters Safeties will also take care of Gap Exchange and scraping to take the QB on the Zone Read play, allowing the LBs to only to focus solely on the RB and the Dive portion of the Gun Triple Option.

I had to do a good bit of research to write this piece to supplement the video.  I played Inside LB in H.S., but it is the one position I haven't ever coached.  Stuff I borrowed most from was from the 2008 Nike COY book, Pat Narduzzi from Michigan State's talk on The Flexible 4-3 Over Defense.  Also, I got good info from the 2009 Nike book, in talks from Mark Dantonio from Michigan State and Nick Rapone from Delaware, and from the 2010 book, Jay Bateman from Elon University, Mike Cassity from Marshall, and John Chavis from LSU.  I meant to look at Jerry Gordon's book for more info on Quarters coverage, but my 15 mo. old put it somewhere that I can't find it, lol.

Setting the Front

Having two high safeties means that not every WR will be covered by a LB/DB.  The LB can find himself in a catch-22trying to be in the box to defend the run and out of the box to help defend the pass.  LBs must be able to run to do both vs. the Spread, but how you set the front can help your LBs to do their job.

The defensive call will be "Over 4."  Over sets the Defensive Line and Linebackers to the strength of the formation and 4 is Quarters coverage.  The strength will be set to the TE side.  If there is no TE, the strength will be set to the Field versus 2 X 2 sets (2 WR/TEs on each side).  The 3 technique DT, the 9 technique DE, and the Mike LB will always align to the strength call.   The 1 technique NT,  the 5 technique DE (Fox), and the Will LB will always align away from the strength call.  Arizona also lined up their strong-side DE in a 7 technique instead of a 9 technique quite a bit.

The Nickel/Sam LB will normally align to the Field (except for 3x1 Trips into the Boundary) and  vs. 2 WRs, he will walk out half-way between the #2 WR and the OT.  He is completely out of the box.  His width can be adjusted according to down-and-distance.  He can be walked all the way out over the #2 WR in passing situations or he can cheat in his alignment in running situations.  The Nickel/Sam LB will walk out halfway between the #2 and #3 WR vs. 3 WR sets.   

The Will LB is in the biggest position of conflict vs. 2 X 2 sets, and he will align into the Boundary, away from the strength call.  Setting the strength to the Field allows the Will LB to play the #2 WR and be responsible for the B gap instead of the A gap, so he doesn't have as far to go.  The Will LB doesn't have to walk out half-way to the #2 WR; rather, he can stay in the box to help vs. the Oregon run game.  The weakness of this defense is the Out route by the #2 WR.

Here are some ways to address this coverage weakness while staying gap-sound vs. the run.  The first thing a DC can do is the pinch the DE into the B gap so the Will LB now has the C gap.  I saw Boise St. in a bowl game a few years back actually align their Boundary DE in a 3 technique so their Will LB was able to widen all the way out to the #2 WR since he was a C gap player.  Personally, I prefer to pinch the DE on occasion because you don't give away what you are doing by alignment.  Also, the DE in the 3 technique every play will have a difficult time being the Contain rusher, much less getting a pass rush.

Another thing to do is to employ a "2 Read" concept to the Boundary.  "2 Read" can mean different things, so let me explain.  2 Read is actually Quarters coverage unless #2 runs an Out route, then the CB will break on #2 and the Safety will cover #1.  This is a dangerous coverage if it is only something you only run on occasion because of the risk  of mental busts and giving up big plays.  An easier way to prevent the Out route on 3rd and 4 is to run Cover 6 (Cover 2 to the Boundary and Quarters to the Field).  I personally don't feel that it's worth the risk of  busting a coverage and giving up a big play to stop a 5 yard pass, so I would rather show Cover 4 pre-snap and roll the Corner down to Cover 2 to the Boundary as a change-up to Quarters.

The LBs need to know that the strength call changes vs. Trips sets in 10 personnel (1 RB, 0 TEs).  Now, the strength will be set away from Trips into the Boundary to the 1 WR side.  This is done to help out the Will LB, who again is in the biggest position of conflict.  He must be able to match up vs. the #3 WR in Trips vs. the pass in addition to having gap responsibility vs. the run.  Setting the strength to the 1 WR side allows him to be a B gap player instead of an A gap player to shorten the distance he has to travel between the two responsibilities.

If the Offense lines up in a 2 X 2 set with two TEs, the strength is set to the Field. Trips Empty sets with a TE will still have the strength set to the TE side.  If there is one TE, the rule is to always set the strength to that TE.  

Trips Empty 3 X 2 sets will be the same as Trips 3 X 1 sets, where the strength call will be set away from Trips. 

Also, to the nub (TE only) side, I would check  to Cover 2,  making it Quarter-Quarter-Half or Cover 6 (Cover 2 to Boundary and Cover 4 to Field) to put the Force player, who is the CB, in a position to attack the offense at a 45 degree angle to better constrict our opponents' strongside running game.  I will show the video in the DB Play and Coverage Fundamentals post coming in a few days that shows the benefit of Cover 2 to the nub side.  Also, look at The Force article video I did recently for some good cut-ups of this.





Run Fits vs. 10 Personnel

Quarters coverage allows the LBs in the box to fast flow to the playside because they don't have to worry about cutback.  The Force players to each side (Nickel and FS) will take care of cutback on Full Flow (QB and RB in same direction) run away from them.  Also, vs. Split Flow or Triple Option, the LBs do not have to worry about gap exchange with the DE.  The LBs are only concerned with the RB and they are fast flow.  The FS will take care of the QB on the Option to either side.



Here is the video:

LB / Nickel Play
1.  Good LB Play
2.  Good Nickel Play
3.  Nickel - Force on Run to you, must cover Bubble Screen
4.  Nickel Mistake - Fit outside of RB
5.  Will vs. Power - Shoot thru first playside gap you see
6.  LB Mistake - Backside LB must shoot thru first playside gap he sees vs. Power
7.  LB Mistake - False step
8.  LB Mistake - Stay on feet
9.  LB Mistake - Missed tackle
10.  LB Mistake - No one in A gap
11.  Will LB Mistake - Must attack
12.  LB Mistake - Fill to wide vs. Power, must come tight off double team
13.  LB Mistake - Must get over top of double team
14.  Will LB Mistake - Stay in box, tight D gap



Also, Boise St. got some huge tackles for loss plays by blitzing their Mike LB to the A gap away from the RB.  He may have been just reading it really fast, too.  It was hard to tell.  Check out the cut-ups:
