When looking at the Zone Read one has to admire the simplicity of the play and how effective it is. Defenses for decades had the advantage against offenses because it was an 11 on 10 game (the offense minus a QB). The popular West Coast and Power “I” offenses of the ’80s and ’90s took the QB run out of the playbook, and defenses feasted. As the spread began to proliferate through the football ranks the defensive stranglehold started to show some cracks. Coaches like Urban Meyer and Rich Rodriguez began to tear through defenses in the early 2000s, and Vince Young ran to a Rose Bowl and National Championship behind the play. It is one of the first plays an offense installs when putting together a playbook, and after close to two decades of spread dominance, it’s still a defense killer.
In a single-gap defense, the initial thought is to align the defender responsible for a given gap head-up in that particular gap. In theory, this makes it easy for the defender to read his keys and react to the ball aggressively. Offenses play on this alignment rule with zone blocking, particularly the zone read. As the ball snaps the offensive line steps in a certain direction, knowing that by moving the gap, the defenders will move too. In order for defenses to combat this, the defensive line and linebackers must react off each other and gap exchange. By playing off anchor points (or D-Line gaps),the defense can confuse the offense and stay one step ahead.
Using the Under Front to gain an edge versus Trips.
The 3×1 Dilemma
While working at Baylor, one of the first questions the defensive staff would get from visiting coaches was, “How do you defend Trips?” The Trips formation stresses the defense to the max. By using a 3×1 scheme, offensive coordinators have a plethora of options to attack a defense. If the defense stays in an Over front and tucks the Mike in the strong side “A” gap, the offensive coaches know that the defense is either in man or spinning to single high coverage. By kicking the boundary safety to the field, the offense gets a guaranteed one-on-one match up with the boundary corner. Even if the defense is dropping an end, or slinging the weak side backer under the single receiver, the top can easily be blown off if the offense has a stud “X” receiver. Against RPO teams a tucked Mike gives offenses the option to read the field safety. This is where the “Spot Draw” can give fits to a defense that is playing an Over front.
The power run game is not dead. As spread offenses proliferate through all divisions of football, the “Power” play is still a staple of many offenses. Defenses must be able to adapt to any formation without subbing players because of the tempo being thrown at them. This can cause a dilemma when a defense’s base scheme is a 4-2-5. When teams insert an “H”, or fullback, a defense does not have to spin to a single-high in order to gain an extra man in the box. Instead, use the natural structure of the 4-2-5/4-3 Hybrid to the defense’s advantage.
