“How Do You Play Trips?” Pt. 3 – Defending the Run

Defending a spread offense’s 3×1 package run game from a two-high shell.

When developing a defense it is important to start with the front and work back. Lining up correctly to formations, understanding keys, and developing a plan to stop the run all starts with the front seven. In a 4-3/4-2-5 (or 3-4 Hybrid) defense, the secondary players become the adjusters. Playing a single-gap defense and using formations to dictate alignments allow defensive players to see the formation quicker and align correctly. Each player in a defense is anchored to one another in some way. Understanding these anchor points, and how they change depending on formations, is crucial to the success of any defensive unit.

The Spread’s utilization of space has put aligning correctly every play at a premium. It is easy to align to a simple 2×2 formation, but when offenses utilize 3×1 formations (primarily Trips Open) the defense must understand how it adjusts will dictate their areas of weakness. Offenses make use of Trips formations because it forces the defense to give something up. To gain a six-man box a defense must spin, either to the Trips or away.  Continue reading ““How Do You Play Trips?” Pt. 3 – Defending the Run”

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 the Diamond Formation

Ideas on defending a unique and multiple set.

01-wvu-diamond

The inverted bone offensive set has become an integral part of many spread offenses over the past decade. The set is similar to the 12 personnel “Ace” set (2×2 with two TEs) and reflects how offenses have gotten creative by taking the TEs off the ball. Any even set with a “pistol” backfield has created a two-way-go with their play calling. Defensively this puts pressure on the players to set the front to the strength. With modern football moving more towards hybrid players, the Diamond set allows for offenses to move seamlessly from 30 personnel to 20/10/11 personnel. Add tempo to the mix, and defenses now have to line up correctly to multiple sets without a sub to tell them what they are getting.  Continue reading “Defending the Diamond Formation”

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.
