Running Dime as Your Base – A Lesson From the Big 12

Welcome to the Big 12 where Dime has now become your base.

The Big 12 has always been on the outer limits of what coaches are willing to do on offense and a graveyard for “guru” defensive coordinators (just ask Diaz and Strong). Defenses in the Big 12 play more snaps than the average Power 5 defense. Tempo and the Air Raid reign supreme in a league that prides itself on scoring points. The knock on the league has always been the defenses in the conference. To many outsiders, the Big 12 is offense first, and it is, but if you are looking to defend the spread, there is no other place to look – they live with it every day.

If looking at defensive stats alone, the Big 12 is on the outside looking in, but there is something to be learned here. Starting in 2016, teams in the Big 12, primarily Oklahoma St. (2016) and Iowa St. (2017), began using a modified Dime (3-down) and Nickle (4-down) package to combat the Air Raid heavy teams in the league. I discussed in January’s article about how teams are becoming more fluid in their fronts; switching from 4-down to 3-down without losing scheme.

The Dime package utilized by Iowa St. in 2017 was no different. Versus a run-heavy Oklahoma team, the Cyclones relied on a modified 4-down defense to defeat the Sooners in Norman. There ability to switch from a 4-down to a 3-down without subbing made the scheme a perfect fit for the multiple Sooners. With a TE like Mark Andrews and an H-back like Dimitri Flowers, the Sooners could give multiple looks without subbing. This fact alone is why the Big 12 is so innovative on defense. Hybrid players are a premium in the league. In Iowa St.’s season finale versus a high-powered spread attack in Memphis, Iowa St. utilized the 3-down version of their hybrid Dime to defeat Memphis 21-20.

The Dime/Nickel hybrid defense has become Iowa St.’s base defense and is fluid between the different front structures. When the Cyclones go 4-down, it is no different than if they are blitzing a linebacker from their Dime package. The coverages are similar too. Here is a look at the two base defenses:

Lining Up to Ace

What to do with those two extra gaps.


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”
