One simple coverage tweak can add numbers into the box and free up your LBs versus Y-off offenses.
I learned about using a “key” read on an offset TE (H-back) in 2017 when I heard Don Brown speak at the Lone Star Clinic in College Station. In his words, he stated, that without City Check (Cover 1 with keying safeties), he didn’t know where he’d be as a coach. Those are powerful words from one of the best defensive coordinators in college football. Sometimes you need an extra fitter on the H-back, especially as more Spread teams base out of 11/20 personnel sets (Y-off), and this was exactly what I was looking for.
Don Brown’s City Check or “Key/Fox,” as Dave Aranda (LSU)/Todd Orlando (Texas) refer to it, is a Cover 1 adjustment to any two-back formation, and can also be used if the H-back turns into a traditional TE on the line of scrimmage. Both safeties are aligned 8-10 yards deep at the edge of the box and are keying the FB or offset TE depending on personnel grouping. This is a great way to give a two-high look pre-snap (Quarters), then add numbers post-snap (gapped-out single-high). Below is a diagram of Michigan running the scheme versus a 21p “I” Twin formations.
Both safeties are slightly tilted in and focusing their eyes on the FB. Whichever way the FB inserts or moves, the safety to that side will trigger down to “cap” the box fit. Most defensive coaches want plus numbers in the box. The term cap refers to the third man responsible in the fit. There should be an inside and outside shoulder player on the ball carrier. The “capper,” or third fitter, caps or tops the fit.
Inside the box, the LBs are focused on the RB, and if the back were to go out for a pass (more likely versus a Shotgun offense), the LB to the RB’s side would take him. The rest of the secondary is locked on their man. In terms of pass coverage, the safety away from the inserting FB will work “through the Post,” creating a Cover 1 look. Below is a clip of the play illustrated above, a simple Iso from 21 pers. I Twin.
The motion by the Badgers’ FB triggers the safety to the nub-TE’s side to start working down. Wisconsin is used to seeing City Check from Michigan and understands how to manipulate the trigger. The open “A” gap is actually away from the motion, and the FB works back to it on the snap of the ball. Inside the box, the LBs must understand the leverage of the secondary and how the FB’s movement will trigger one of them. In the clip above, the ILB hits the FB away from the dropping safety (referred to as “boxing” the block), essentially forcing the ball carrier to the safety. The overall result is a short gain.

One of the greatest luxuries in football is when a defense has enough depth in the secondary to create a Dime package. As spread has become the norm in football, the Nickel package, replacing a linebacker with a secondary player (usually a safety), has become the norm and many defenses’ base. Most teams have “tween” or hybrid players. Utilizing these players on defense has made it easier for defensive coordinators to adjust to the onslaught of spread teams. The Dime package, in particular, is different than its sister the Nickel package. Instead of replacing a LB with a safety, the Dime package puts two defensive backs in and replaces either two LBs (four-down) or a LB and a defensive lineman (three-down). The specific package being discussed in this article will cover the three-down, three safety Dime package most generally seen in college today.
A 3-4 Base
If a defense’s base is a 3-4, it can easily adjust to the spread by putting a Nickleback at Sam, much like its counterpart, the 4-2-5. A three-down Dime package takes the Mike off the field and inserts either a safety or a CB depending on the DC’s preference and the scheme being used. The front most used in a Dime package is the Buck Front or a 505 front. This ensures an edge rusher on either side of the quarterback that will define the box. The Nose’s role is to get a vertical push on the pocket and make the QB move. Below is a diagram of a 3-4 Buck Dime Package:
The first decision that has to be made when developing a Dime package is who is going to be part of the Dime package personnel? If looking to run more of a man scheme, a DC is more likely to bring on two cornerbacks and leave the two most athletic LBs on the field. As stated earlier, more defenses are shifting to a Nickel/Hybrid base. This means the traditional Sam LB is actually a safety. In the case above, the Nickelback is more than likely a third CB while the Dimeback is another safety. Continue reading “The Dime Package”
Lining up to an Ace set can be one of the most difficult formations for any defensive coordinator. The two extra gaps created by the TE’s force the defense to account for them in the run fits. If the offense decides to line both receivers up on the same side (Trey), it creates a three-receiver formation, with the added pressure of an extra gap to the strong side. Away from the Trey side, there is a “nub” TE (TE with no WR) and another gap created that the defense has to account for and subsequently defend (versus a traditional 11 personnel set, the defense can easily address the newly created gap). The concern in 11 personnel shifts to how a defense addresses the cover down to the two-speed side.
When offenses run Ace Trey, the defense has to account for two extra gaps as well as the cover down on the two-speed side. If the offense runs its sets from the pistol, they literally have two strong points of attack. The Ace grouping of formations is very similar to the Diamond in the fact the offense can max protect and run with extra blockers from an even set, essentially gaining a two-way-go and the ability to attack the side the offense feels it has the most advantage. Unlike the Diamond formation (inverted Bone), where the extra gaps can be created by the backfield post-snap, the Ace formations establish the gaps before the snap of the ball. This immediate addressing of the gaps forces the defense to show its cards. Continue reading “Lining Up to Ace”
