We’re going to take a look at “spread” formations, and how we adjust to 10 personnel in 2×2 and 3×1 sets. We can use a variety of methods including cover 3, split-field robber 4, and even a 3-4 robber 4 look called “Stack”

In 10 personnel 2×2 sets, we can run Hokie Robber 4. Our SLB will robber the slot to the field with our safety to that side playing in the apex (6 yards off and between the #2 and EMOL). On the boundary side, the CB will play 5 off and outside leverage while the safety plays 8 yards off and stacked over the #2.

An adjustment vs 2×2 10 personnel we can run Stack Robber 4. Stack is an odd front. It’s a 3-man defensive line that 1-gaps and slants to the “strength” which we label as tight end/trips/field. In Stack we can robber both sides, taking away screens and other flat combos away.

Versus 3×1 10 personnel, we can robber the trips side while playing cover 2 or 4 to the single receiver to the boundary. If you’re getting a lot of swing routes maybe play cover 2 and have the CB play the flat.
