The “Nub” Side

Defending single-width formations.

There are certain formations that pop up during a season that can give a defensive coordinator pause. Unbalanced sets, for instance, are used by many offenses to force 16 to 18-year-old athletes to think on their feet or force a defensive coordinator to burn a timeout. Pro spread offenses use tackle-over sets to confuse the defense and gain leverage, while 10 personnel spread and two-back offenses utilize unbalanced sets to work quick motion from the single receiver side (“X-off”). Though “nub” formations are not unbalanced, they are very similar and continuously give defenses trouble. When the formation is combined with RPO and Air Raid schemes, it can put immense pressure on DCs.

Single-width formations are paradoxical. On one side an offense has multiple receivers, while on the other it has a running formation. “Nub” formations force the defense to acknowledge a true “run” side, while also defending multiple receiver formations. Offenses that utilize TE sets can create leverage issues or force a secondary player to be left by his lonesome against a bigger player. Many defenses will choose to spin against “nub” formations to gain extra men in the box and replace lost overhangs.

As modern football progresses, more offenses are choosing to go away from under center formations. This allows the offense to have a two-way go in a Pistol formation or a “read” side in an RPO offense from the gun. There is nothing more threatening than an offense that is powering the ball down the field while implementing RPOs. Packaging plays forces the defense to stay even and protect the run fits and pass distribution, all at the same time. Instead of spinning, a defense needs to stay in a two-shell look and develop a game plan dependent on the tendencies and personnel preference of the offense.  Continue reading “The “Nub” Side”

Defending 3×1 Formations – Solo Coverage

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.  Continue reading “Defending 3×1 Formations – Solo Coverage”
