The use of motion has been one of the major trends facing defensive football in the past several years. Analytically, the use of motion by offenses has a distinct advantage. Defenses are reactionary in nature, so moving someone pre-snap can give the offense an edge or throw the defense off balance. Seth Walder, ESPN Sports Analytics, tweeted this about the Week 1 NFL usage of motion:
So we've shown before that motion at the snap is an edge for the offense.
And crazily, the top 12 teams here all won in Week 1.
But guess what: EPA/P league-wide was *not* higher on motion at snap plays in Week 1.
EPA/P is the average “Expected Points Added” divided by the number of plays. This stat illuminates how efficient an offense is as they go down the field. EPA as a stand-alone stat rates how many points an offense is expected to gain (or lose) depending on the yard line and Down & Distance. Each play is rated against where they started and where they finished. That number is the plays EPA. Since yards gained is a flawed stat, EPA uses expected points from historical data to calculate how effective the play was at creating scoring opportunities. Did you put money in the back or take it away? Defensively, this can be used to measure the effectiveness of calls during a drive.
Two types of motion are studied by analysts. Pre-snap shifts (everyone is set) and motion as the ball is snapped, or what ESPN refers to as “Snap Motion.” Shifts are when a player moves from one spot and establishes himself in another. He is not moving when the ball is snapped. Snap Motion is when the offensive player is moving horizontally as the ball is snapped.
Football is about leverage. Motion uses speed to leverage the defense. Since NFL defenses are so man heavy, it is not surprising that the use of Snap Motion has led to higher EPA/P success.

Welcome to the Big 12 where Dime has now become your base.
The Big 12 has always been on the outer limits of what coaches are willing to do on offense and a graveyard for “guru” defensive coordinators (just ask Diaz and Strong). Defenses in the Big 12 play more snaps than the average Power 5 defense. Tempo and the Air Raid reign supreme in a league that prides itself on scoring points. The knock on the league has always been the defenses in the conference. To many outsiders, the Big 12 is offense first, and it is, but if you are looking to defend the spread, there is no other place to look – they live with it every day.
The Dime package utilized by Iowa St. in 2017 was no different. Versus a run-heavy Oklahoma team, the Cyclones relied on a modified 4-down defense to defeat the Sooners in Norman. There ability to switch from a 4-down to a 3-down without subbing made the scheme a perfect fit for the multiple Sooners. With a TE like Mark Andrews and an H-back like Dimitri Flowers, the Sooners could give multiple looks without subbing. This fact alone is why the Big 12 is so innovative on defense. Hybrid players are a premium in the league. In Iowa St.’s season finale versus a high-powered spread attack in Memphis, Iowa St. utilized the 3-down version of their hybrid Dime to defeat Memphis 21-20.
The Dime/Nickel hybrid defense has become Iowa St.’s base defense and is fluid between the different front structures. When the Cyclones go 4-down, it is no different than if they are blitzing a linebacker from their Dime package. The coverages are similar too. Here is a look at the two base defenses:
Description: As the spread becomes more of the norm in all regions of this country it is important for coaches everywhere to have a resource for defending the modern spread offense. Cautious Aggression: Defending Modern Football is that resource for coaches. The schemes described in this book are tried and true methods for defending some of the best offenses this country has ever seen.
Starting with “The Why” and ending with “The How.” Cautious Aggression gives coaches a defensive philosophy they can trust. Using diagrams and concise explanations, the book lays out a formula for success for coaches to utilize in their own schemes. Below are the chapters:
Argument for Two-High
Defending the Modern Spread Offense
Defending Run/Pass Options
Systematic Creativity of a Quarters Defense
The Art of Match Quarters
All About the Cover Down
Designing a Modern Defense
Setting the Strength
Defending Formations into the Boundary
Coaching at the lower levels of football bring its own issues to the table that many Division I football teams do not face. Cautious Aggression: Defending Modern Football is written for all coaches. The experiences Coach Alexander gained while coaching for Baylor Football combined with his experiences at the high school level has given him a unique perspective on defensive football. Many of the concepts and theories in this book have been adjusted to fit the needs of high school and small college coaches around the country. Come learn “The Art of X.”

Offenses use Flare & A-Behind motion to force the defense to move. Don’t get out leveraged.
Quick motions are a great way to get the defense out leveraged. The fast motion is like eye candy for linebackers and safeties, using the speed of the receiver to get the defense to over shift. Jet motion in particular forces the defense to try and cut off the motion because of the tempo at which the motion attacks. To combat Jet motions many defenses turn to spinning towards the motion so the overhang can force a cutback. Though this technique can work in the shorthand, spinning to the motion tends to leave teams vulnerable away from the spin safety.
As offenses have evolved, quick motions have become an integral part of spread concepts. In a traditional motion, the WR changes from one side of the formation to an another on a flat path. The speed of the WR depends on the route he will run. For the most part, traditional motions have the WR jog across the formation. As the spread has evolved from traditional motion to jet motions, another way offenses have learned to attack how defenses react to motion is by flaring the running back out of the backfield. This type of quick motion forces the LBs to push and gain width between their run responsibility and the man they are responsible for in the pass. This width creates conflict, and as all defensive coaches know, offenses love conflicted players. Continue reading “Defending Flare/Quick Motion”
Improve your off-season self-scout by creating special cut-ups.
Off-Season Film Study
Film study is one of the greatest ways to improve on schemes and calls made the year before. In order to correctly monitor the calls that were being made a defensive coordinator must look at certain scenarios where he struggled the year before. It is important to analyze the season with a critical eye and always ask, “How can we improve?” From player personnel decisions to eliminating calls altogether, using cut-ups from the year before allows the DC to evaluate when and where plays were called. Remember hindsight is 20/20. One way to increase improvement from year to year is to view cut-ups that highlight defensive deficiencies and struggles. There are multiple ways to create cut-ups, but it is important to have certain ones created that highlight the unique ways offenses attack a defense while allowing the DC to have hard data on what needs to be fixed within the scheme.

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). Even 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.

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 defensive 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”
