Coaches and quarterbacks nowadays are exceptional at identifying and exploiting defensive weaknesses. Defenses now, with the rise of spread offenses, often give away their soft spots by how they line up, and the myriad of reads, packaged plays and options make exploiting those weaknesses ever simpler stuff.
But football is a game of give and take, and defenses are responding. And they are reacting to the up-tempo read-on-the-run offenses of today in two main ways: By becoming more flexible, with more hybrid type defenders to deal with hybrid type offensive players, and doing increasingly more of their own attacking.
The key for defenses then is to attack, but to attack intelligently. Offenses will exploit obvious weaknesses, so the best approach is for the defense to combine aggressive tactics with sound schemes and even to set traps for the offense. And one of the best — and oldest — methods for doing that is to combine an overload blitz with angle stunts that go the opposite direction. This tactic is increasingly popular at every level of football, particularly against nouveau spread attacks, but it has old, old roots.
Specifically, the combination of overload blitzes to one side with angle stunts going the other way was a feature of one of football’s most dominating defenses, the 5-2 “Monster.”
In the old 5-2 Monster defense, the defensive aligned with five defensive linemen, two linebackers, and a “Monster” defender who lined up either to the wide side of the field or to the strength of the offense, typically the latter. With a nose guard lined up directly over the center, the defense had three additional defenders lined up to the offense’s left and four additional one’s to the offense’s right. This gave the defense the chance to overpower offenses to their strength side, where they typically liked to run to.
But, as the defense evolved over time, this increasingly became a trap for the offense. Against the 5-2 Monster, offenses typically liked to either call plays to the weakside of their formation, or even let the quarterback audible to them at the line, just as pro-style and spread quarterbacks today check to runs away from the defense’s numbers. Indeed, much of the modern run game is simply about identifying where the extra defenders are and getting away from them, and running away from the Monster seemed as good of a plan as any.
Except it was exactly what the defense wanted the offense to do. The reason for this was because most of those 5-2 Monster teams, despite lining up with extra players to one side versus the other, used “angle stunts,” or defensive line movements, away from the Monster player. The net result was that the 5-2 Monster was a balanced defense.
Thus the Monster’s great success — and it was one of the most popular defenses in football for at least thirty-years — was as much about psychology as it was schematics; there were unbalanced defenses and there were balanced defenses, but the Monster was uncanny at trapping the unwary coach and quarterback into running into the strength of the defense: Against balanced defenses, the offense wants to run to its strength, or to the tight-end. Against unbalanced defenses, offenses want to run wherever they have a numbers advantage, typically to the weak side. The Monster wreaked havoc with that kind of calculus.
While the 5-2 Monster may no longer be the defense du jour, defensive coaches have not forgotten its lessons, and instead apply them every week across football. It’s just a matter of adaptation.
