5 Tips for Developing a Blitz

Simple rules for blitzing.

Every defensive coach in America is looking for new and improved ways to attack offenses. Blitzing allows the defensive coach to gain a little control on the offense by creating cutbacks or forcing a quick throw. Sending extra men creates changes in the defense that affect players from the front to the secondary. Understanding how each pressure affects pass distribution and run fits is crucial for creating successful blitzes. Leave a gap open and the offense will find it. Over-rotated or leave a man uncovered in the back end and the opposing team’s band is playing.

Whether a pressure or a blitz, simple rules must be created when designing blitzes. The main goal of each blitz or pressure should be stopping a scheme the opposing offense is trying to utilize. Not all pressures are created equal. Some are more dangerous than others, but when designing a blitz there are five things a defensive coordinator should consider.

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:

.99 C3

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”

Defending the Spread From a 3-4

Running an Okie Front to defend the modern spread attack.

Defensive linemen are at a premium. For many teams, it is hard to field a deep roster that can lend itself to a four-man front. Running parallel to the defensive dilemma of lineman depth is the popularity of the spread. A natural conclusion for many defensive coordinators around the country has been a shift away from a four-down front and into a 3-4 scheme. The flexibility of the 3-4 and the added athlete on the field makes the scheme spread friendly. The multiplicity within the scheme allows DCs to attack the offense from multiple directions without sacrificing pass distributions. Running a two-high scheme behind a three-man front meshes well with teams that have a history of running a 4-2-5 or 4-3.

The Okie Front, in particular, can be of service when defensive coaches are looking to defend the spread from a three down front. With a 5 technique, a shaded Nose, and a 3 tech. (or 4i) to the weak side, the Okie’s anchor points fit the spread much like its four down sister, the Under Front. To the weak side, the Jack linebacker (boundary OLB) is technically a wide “9” in the run fits and controls the edge of the box to the boundary. The Jack LB, in particular, is useful when defending offenses that like to attack the boundary through the air. Even though the Jack is technically a conflicted player (he is responsible for the “C” gap), his alignment allows him to read the offensive tackle and slow play the run. In most four down fronts, the boundary OLB (Will) is the “fold” player and is considered conflicted because his gap is in the box. The Okie Front eliminates the fold and replaces it with a loose overhang (much like a natural Will/DE exchange in a four down front). Continue reading “Defending the Spread From a 3-4”

Teaching Gap Exchanges & Defending the Zone Read

Teach the LBs to read their anchor points & play assignment football.

Without moving the front on a line stunt, a defensive coordinator can set up the fits to create gap exchanges and stay sound against zone read teams. Even if a team is running a simple inside zone scheme, teaching gap exchanges between the front seven can allow the front to “cut-off” the runningback’s path and force a cutback to free hitting linebacker. Understanding the structure of a front is key for any defense to be successful. Teaching the LBs to read their “anchor points” can allow the defense to be fluid against zone schemes. Defensive lineman must know their gap assignments just as well as the LBs. In the age of spread, it is important for the front seven to understand how each gap is going to be fit and how each player’s movements effects the link behind them (DL-LB-Secondary). All great defenses start with a solid technical structure.

Spread offenses want to attack the open “B” gap and the conflicted LB. The zone read is nothing more than a modified Dive Option. Add a bubble route (or any receiver screen) and the offense is running a modern version of the Triple Option (the offense can use orbit motion to create the same look too). 01-titleEven if the offense is aligned in a spread set, option structure is still there. As a DC starts to game plan and create a defense to defend a spread attack, he must look at a zone-read heavy offense as though he was attacking a Triple Option attack. Someone has to take the dive, the QB, and the pitch. How a DC chooses to set the front will determine who carries the ball versus a zone read/option team. In the diagram to the left, the defense is set up in an Over Front to a 10 personnel 2×2 set. The Sam can cover down to the slot because he does not have a box fit. The Mike and Will each have a gap to hold versus a run. Since the front is set to the RB (5 and 3 technique), the most likely scenario versus a zone read is a handoff (dive), the Will folds into his box position and the Sam takes the bubble (pitch) away from the play. By setting the front to the back, the DC has created a predictable situation in which the QB will hand the ball off to the RB. Just on alignment alone, a DC can force the offense’s hand. Defending zone-read heavy teams is all about cover downs and changing the “B” gap. The most important decision a DC can make versus spread teams that run read/option plays is to decide who is the worst ball carrier, and force that player to carry the load.

Defending 20 Personnel – Over vs Under

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 01-pop-setsattack 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 tspin-to-hhat, 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?

Defending Jet Motion

Don’t take the bait. Don’t get out leveraged.

01-auburn

The jet motion is a great leveraging tool that offenses use to either move the defense (to counter the opposite way) or cut them off (speed kills). Auburn under Malzahn has utilized the jet motion to create deception and outmaneuver opponents. The speed at which the jet motion attacks, forces the defense to recognize the motion and adjust accordingly. Because the offense is using a fast motion, the defense is forced to plus alignments or spin an extra player down to the side the motion is moving. Many times, an offense uses their best athlete on the jet motion to focus even more attention on the movement.  Offenses can even use the jet motion as a decoy because the defense has to honor the motion. To gain width, or to freeze an OLB/DE, offenses will send a jet motion to one side and run a play going away. This “freezing” of the defense allows an extra lineman to climb to the next level. This focus causes tunnel vision and can lead to exposure away from the direction of the motion.

Offenses use motion as a leverage tool. The Slot-T version of the spread, which Auburn runs, uses the jet motion to move the defense into compromising positions. Every 03-auburndefensive coach knows that when an offense uses motion (especially jet motion), the defense is forced to adjust promptly to the new formation. As stated earlier, the speed of the jet motion can make defenses over rotate to counteract the quick rotation of the offense. For many defensive coordinators, it is easier to rotate safeties (spin) than to bump linebackers because of the tempo at which the WR or slot is running. The introduction of unbalanced formations (X-off) and the utilization of the quarterback in the run game have made it more difficult for defenses to defend jet motion teams. In the picture above, Auburn used an unbalanced set to attack the Alabama defense. Out of the stack set shown, the offense can run a double lead jet stretch, running back counter weak, jet power read with two lead blockers or any QB run they choose. With so many play variations off of one formation and motion, it is no wonder many spread teams are using this type of motion to build whole offenses around. Any time the QB becomes a runner, the defense is stressed even more. The added value that the jet motion gives teams is undeniable. Continue reading “Defending Jet Motion”

Zero the Mike & “What’s a ‘Belly-Key’?”

Double gap the Mike in a single gap scheme.

Zero the Mike

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, with the understanding 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 (anchor points) and utilize gap exchange. By playing off anchor points (or D-Line gaps), the defense can confuse the offense and stay one step ahead.
