Kick the coverage with out the spin.
The biggest issue facing defenses when defending 3×1 formations is the run/pass conflict of the Mike. No other player in a 3×1 formation has more on their plate than the leader of most defenses. In modern football, the age of a “plugger” at Mike is over. Each LB must be able to cover underneath routes and understand how their run fits relate to their pass drops. Defenses can no longer afford to drop their LBs to “zones” or landmarks. Each player is a link in a chain. As the spread becomes a permanent fixture in most regions’ football cultures, defenses are turning to match schemes to help alleviate the issues seen in traditional defenses.
Traditionally, teams have spun to the three-receiver side to allow the Mike to stay in the box, switching his responsibility of relating to the #3 receiver to “plugging” the middle of the formation. Eliminating this run/pass conflict helped defenses against the “spread-to-run” offenses but it opened them up to high percentage throws that could easily become fatals (TDs) when those offenses ran play -action. In the diagram below, an Over Cover 3 scheme is shown:
Right away, the main issue with Cover 3 or “kick” coverage to Trips is the backside corner is in man-to-man coverage with the single WR. Offenses traditionally have left their best receiver at the “X” because of this defensive scheme. The best offensive receiver on the field is lined up across from a player with little to no help. This can spell disaster for defenses. As the spread as evolved, offenses have developed reads for the third level. If a defense spins to a 3×1 formation (“kick”) the offense can easily check to a backside choice route depending on the leverage of the corner. For most, this is a post route ran right off the back of the kicking safety. This is a high percentage throw that can spell disaster for defenses.

How to attack 2o pers. using the offense’s tendencies.
There is a reason so many spread teams are using 2o personnel as a base formation. Slot-T teams like Auburn use jet motion and pulling guards to out leverage the defense, even using RPOs to find wide open receivers downfield. Florida St. uses a split-backfield to attack the defense with speed to the edge. Teams like Baylor and Ole Miss use 20 pers. formations to use RPO style attacks, Baylor with the third level vertical option routes and Ole Miss with Arc-Read RPOs. There are multiple ways to attack a defense from 20 pers. just using the backfields alone. Each set can create a different read for the QB (all this without using unbalanced and motion). The diagram to the left depicts some of the more popular backfields an offense likes to run out of 20 pers (this doesn’t even include Pistol or “I” sets). When breaking down a 20 pers. offense, each backfield creates a new formation. If an offense uses each one of the above backfield sets in their offense, it forces the defense to look at the formational data with a more critical eye.
For a defensive coach, 20 pers. causes problems not only in the backfield but with the three receivers. There is a tendency by some DC’s to spin against 20 pers. The thought process behind spinning is the offense has added another blocker, and potentially another gap, so to counteract that, a DC will spin. The diagram to the right depicts a defense that has spun to the H-back. This allows the Sam to work back to the box. Though the defense has created a plus-one to the field, they have left themselves exposed to the boundary. All an offense has to do is run a simple Arc-Read to the boundary and the offense has a numbers advantage. If a defense is going to spin against 20 pers., it is in the defense’s best interest to spin weak. Leveraging the boundary allows the pass distribution to the field stay intact, and a defense can play a hybrid quarters scheme to the boundary. The issue with spinning to the boundary is the third-level RPO read off the dropping safety. Teams that run a backside choice with the single receiver will see the dropping safety and run a post/slant right behind him. The best plan of action versus a 20 pers. offense is to stay in a two-high scheme and use the safeties as extra box players. The question now is, what about the front?

Using the boundary CB and Safety to confuse RPO and check-with-me teams.
Basing out of a defense that has split field coverage has its advantages when it comes to 2×1 and 3×1 sets. Many spread offenses split the field themselves, only reading one side of the formation. This allows defenses to take advantage of the one read RPO systems that many spread teams utilize. No matter what the defense throws at a split field match quarters team, it can align in the correct coverage. Another way to protect the defense is to formation the defensive play calls.
The single receiver and slot receivers are the main targets for RPO spread teams. They use the leverage of the secondary against the defense, reading dropping safeties and the depth of the corner. The single WR side usually sees the quick hitch or slant off of play action. Teams like Baylor use the leverage to RPO vertical choice routes. A defense can confuse the QB by playing with the leverage of the secondary pre-snap. This may seem like single-high to the untrained eye, but with a split field coverage scheme, a defensive coordinator can change the leverage to the boundary (single receiver side) and still run the base quarters scheme.
