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 the Spread’s Unbalanced Sets

Ideas on countering the optical illusions of unbalanced formations.

Offenses use unbalanced formations to get the defense out leveraged. An offense does this by creating an extra gap by moving a guard or tackle to the opposite side of the formation. Unbalanced sets are optical illusions created by the extra lineman to one side. Teams can also use wide receivers when creating unbalanced sets. By putting a WR on the line and covering him up, the offense has now freed the single WR (“X”) so that he can motion across the formation. Many defenses refer to this set of unbalanced formations as “X-off” formations.Unlike pro style unbalanced formations that just shift the line one way or another with an extra guard or tackle, X-off formations use a player that is normally static in the motion game.

Unbalanced sets, in particular, are designed to be optical illusions to the defense. In a pro style (11 personnel) unbalanced, the defense is so used to seeing the same Center over and over, that they fail to realize the shift on the line and can’t identify the new three-man surface. This causes the defense to be a gap short and out-leveraged by the offense. In an unbalanced spread set (20 pers./10 pers. – mainly Trips), the offense uses the WRs to create the illusion. It can be hard to identify WRs on the line, especially when tempo is involved. The defense can be surprised by the jet motion from the “X” WR if an unbalanced set goes unnoticed.

Offenses can use quick huddles and tempo to throw off the defense when using unbalanced sets. Defense generally lineup off of personnel and identify key players on the offense (like the Center’s number or a slot WR). It is important to teach the front seven to identify the three-man surface when playing pro spread teams that use unbalanced out of their 11 pers. sets. When facing a spread team that uses WR unbalanced sets, the key is to identify if the single WR is off the ball. To the front side, the secondary players (and cover down) must identify if multiple WRs are on the ball.
