When teams empty the backfield know how to line up.
Teams run empty backfields to isolate WRs and open the middle of the field. With more teams opting for athletic QBs, empty sets have become a way to expand the QB running game. Defensive coordinators that want to keep a six-man box are forced to run “Zero” coverage behind the front with help only coming by late support underneath from the inside linebackers (better to just send a six-man pressure and force an errant throw), or spin to single-high. Either way, “Zero” or single-high coverage, the defense is putting its defenders in one-on-one situations. Split field defense can adjust to any empty set, but it puts the ILBs in conflict. Following base Trips rules and running an Under Front versus Empty, the Will LB is responsible for the “A” gap yet has to cover down to the weak slot. This conflict can be used against the defense and is a primary example of why Empty sets are so hard to defend.
The sister formation to Empty is Quads. This set stresses the defense even more and forces the backside safety to become a box player. The Quads set shifts the defense to the four WR side. This shift puts the DS into primary fit support in the “A” gap and completely takes the Mike LB out of the fit (another reason teams like Quads). By taking a box LB out of his fit, the offense has now forced the defense into an uncomfortable situation. Spread teams also like Quads when they have a stud WR. By alignment alone, Quads forces a one-on-one situation to the single WR side. The DS still can help the backside CB, but with any run action by the QB, or a pulling Guard, the DS must honor his fit and work into the box. This allows a brief window in the middle of the field (high percentage throw). Whether 3×2 or 4×1, the offense can put immense pressure on defenses by eliminating the RB from the backfield. All is not lost, 4-2-5/4-3 split field defenses have several ways they can combat empty backfield formations without blitzing or dropping eight. Continue reading “Defending Empty and Quads Open”
If the offense won’t throw to #1, lock him up and reduce the field.
When defending a team that runs Trips it is important for the defense to have multiple coverage options. Depending on how an offense chooses to attack a defense the selection of the right coverage can be crucial. Being able to switch from base coverage to base coverage allows the defense to keep the offense on its toes. If a defense only runs one base coverage against Trips, offenses will quickly find a way to exploit it. This fact alone should encourage a defensive staff to carry multiple coverages into a game and be able to use them when the opportunity arises.
Many times offenses use the #1 receiver as a decoy or chooses to run him off to create a void so the #2 or #3 WR can run an out route into space. One way to counteract the nonuse of #1 and outs by #2 or #3 is to run Special Coverage. Unlike Stress where the Sam is blind to what the #3 WR is doing, Special eliminates the #1 completely and reduces the field. The Sam takes on the responsibility of a Two-Read CB. His eyes are squarely on #2 and will carry the vertical of #2 if the offense runs vertical routes. Like Stress, the key player is the Sam linebacker and his ability to run with a vertical route. Eliminating #1 puts the Sam on an island with #2. As stated earlier, having options in coverage is important to defending the spread. A defense must be able to adapt to any situations and adjust to any formation/scheme thrown at it. Continue reading “Defending Trips – Special Coverage”
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”
How to break down the D&D data.
Down and Distance (D&D) seems easy enough, right? As the offense moves along the field, their play calling is predicated on the down (how many more plays they have left to get ten yards) and the distance (how many yards they need to get so they can start over). It is a very simplistic stat, but it has major ramifications on how offenses call their plays. Looking at the D&D stat from a simplistic eye will give a defensive coach a wide range look at how often a team runs or passes on a given down. Add personnel groupings and the data begins to get clearer.
In order to truly get a grasp of what an offense is doing you have to create D&D groupings for long (7+), medium (4-6), and short yardage situations (1-3). This can allow a DC to pinpoint what plays are more likely in situations, allowing him to call the correct blitz or pressure at the right moment. Defense is reactionary, thus needs to react off the data that is provided by particular stats, in this case, the D&D. Pundits and coaches say it all the time, football is a situational game. The chess match that is football attests its strategy on several factors: field position, D&D, and what personnel grouping are on the field. Branching from that, formations and run/pass stats. For the sake of this article, MatchQuarters will discuss the breakdown of D&D and talk about the intricacies of each grouping. To understand completely what an offense is trying to do, the D&D should be looked at objectively with field positions groupings. The two data points combined give a true glimpse into the mind of the opponent’s OC. Continue reading “Developing Down and Distance Data”
