Structuring Your Defense – The Front

Just like coverages, a defense should have different fronts to combat a variety of formations & schemes.

Just like coverages in a secondary, a defense cannot live in one front or technique on the defensive line. How a defense structures its front line has a direct correlation to how an offense is going to attack it. Most defensive coaches in America understand that the defensive line is critical to not only stopping the run but putting pressure on the quarterback when he drops back to pass. It is no stretch to say that the top teams in any level of football usually have one of the best defensive fronts for that level.

The front, and subsequently the strength call, create the first line of defense against an offense. In a well-formulated defense, the front seven (and even the secondary) act as links in a chain. The anchor points of these links are always the defensive linemen. Understanding how these links react to each other is critical in developing a plan to stop offenses. Not every front (or strength call) is equal to one another.

Some fronts and techniques are better suited to defend Spread offenses than Power ones, and vice versa. For this reason, defensive coaches should carry multiple fronts for multiple situations. Just like a defense’s coverages and alignments are different when defending a Wing-T team compared to a 10 personnel Air Raid offense, different defensive fronts can help combat the multitude of offenses seen throughout the year, and why every defensive coordinator should carry several fronts in his toolbox.

The advancement (and acceptance) of hybrid players have led many DC’s to switch from three-down to four-down in the same game (or even during the season – game to game). To the point of being multiple and carrying a plethora of calls on the call sheet, Don Brown, Defensive Coordinator for Michigan insist, “If you have more answers in your toolbox then you can go to them throughout the season and it’s a matter of just getting them back on recall.” Having a multitude of options at a defense’s disposal can only add to what it can ultimately stop. More is simply, just more. It comes down to how well you can teach it. Continue reading “Structuring Your Defense – The Front”

Defending Stack and Bunch Sets

Theories on attacking the spread’s cluster sets.

One of the hardest sets in football to defend is the cluster or stack set. Spread offenses utilize this set to get the defense’s outside linebackers in run/pass conflicts. Unlike a traditional 2×2 set, the defense has to adjust to the width of the receivers. Stacking them creates width, and width creates the conflict. Spread teams rely on the open “B” gap to build their RPO’s and offensive gameplan. By stacking the receivers out wide, the defense is forced to adjust. In a two-high system, the player in conflict (usually the Will LB) has to choose, cover down to his receiver or hold tight to the box. If he stays close to the box, the offense is going to throw the quick screen and create a 1-on-1 open field tackling matchup with the safety or corner. In most cases, the defense wants to avoid this as much as possible. On the other end of the spectrum, if the defender widens to the cluster set, the offense has a 4-1 box and a clear running opportunity. Versus a two-high system, there is a great chance for the offense to part the field like the Red Sea for a big gain. Ask any offensive coach, a 4-1 box is a magical thing.

In the image below, Penn St. runs and Under front and “hips” it’s Sam LB to the strength. In most RPO style offenses, this is a clear pass read. The Sam has to honor the run read and step to his gap. Even with zone away and a gap exchange with the crashing DE (in this set the DE has dive), the Sam has to take a step towards the box. The QB is taught to read the Sam’s path and throw the screen. Penn. St. is most likely in a “Cloud” coverage (Two Read) and the safety is bailing on the snap. Easy pickings for any decent offensive coordinator. It’s a conflict of philosophy; the offense wants 1-on-1 matchups and the defense wants a plus-one. In order to create a six-man box and protect against the run, the defense has to spin to single-high, but to keep a plus-one in pass distribution it has to stay in two-high, something has to give. MatchQuarters explores the options.
