Everyone can agree, Nick Saban knows defense. In fact, according to BCfToys.com, which rates college defenses on their efficiency and is “adjusted for the strength of opponent offenses faced,” has never placed Alabama outside of their top 10 in the past five years (low being #7 in 2014 – the only time they were out of the top five). In the past three years, Alabama has been either #1 or #2 in defensive efficiency. One of Saban’s bread-n-butter schemes is his Rip/Liz or Match Cover 3. This single-high coverage is crucial to his run defense and is adjusted to defend the offensive counter move in the four verticals.
Many defensive coaches are familiar with Saban’s Cover 7 schemes that he uses to defend spread teams from a two-shell, but his Rip/Liz tends to be the “go-to” coverage during base downs. Even Clemson has become a heavy user of the Rip/Liz concept, using the scheme to dominate ACC opponents (and also being in the BCfToys’ top 10 in defensive efficiency the last 4 years). Needless to say, the Rip/Liz concept is an important scheme that every coach should familiarize themselves with, even Quarters coaches. What makes the coverage scheme unique is its structure and how Saban decides to spin the secondary (and protect the seams). It’s something defensive coordinators who base out of Quarters coverage understand – Never roll strong.
One of the unique ways Saban protects his defense is in the way he inserts the extra box player. Cover 3 and any single-high coverage is designed to maximize the box players. By spinning, the defense has created overhangs and cover downs to the slot players. These overhangs enable the box players to eliminate their conflicts. In a typical Quarters defense, at least one linebacker will be in “conflict.” This conflict player is typically where spread offenses attempt to attack the defense with RPOs. In the illustration of a typical Quarters defense below, the Will LB is the conflict player. He must fill the open “B” gap while covering down to the slot. Saban and teams that base out of Rip/Liz reduce the conflict for the Will by spinning the safety to his side over top the slot (DS).
In Rip/Liz, the weakside safety is usually the spinning safety. By spinning weak, Saban is ensuring that his front side pass distribution is intact. Versus a basic 2×2 set this allows the ILB closest to the RB to vacate the box if the RB flares because the backside safety can fold into the box vs a QB run and in the pass the Will can handle the middle hole. Where the weak spin helps is against single WR sets (3×1/2×1). Many teams will choose to spin to the Trips side or the passing strength, but this can be dangerous because the defense loses an overhang to the boundary (and exposes the backside CB to a one-on-one matchup).
