4-2-5 Defense: Position Roles and How To Beat It


The 4-2-5 defense became a popular sub package in the 1980’s, as NFL offenses began more pass-oriented, and utilized spread and two tight end formations. As these offenses became more prominent, the 4-2-5 defense began to function as a base defensive package. The defense is a slight variation of the 4-3 defense that uses 4 players on the defensive line, 2 inside linebackers, and 5 “secondary” players. Typically, one of the 5 secondary players is an outside linebacker. The other can be another outside linebacker, a cornerback, or an additional safety. This extra “hybrid” defender drew some defensive coordinators to the 4-2-5 as opposed to the 4-3 defense.


Why do Coaches Run the 4-2-5?

Coaches run this defense for a number of reasons. One appealing reason is the ability to split the field in half both horizontally and vertically. By splitting the defense into 6 players up front and 5 players in the back, it simplifies the responsibilities of the defenders. In addition, 4 players will be on each side of the formation, which will allow for defenses to easily account for motions on the offense. The gap-oriented scheme of this defense helps defend against offenses that are utilizing split ends.

The 4-2-5 is split into 3 zones, with one of the safeties being responsible for himself and a cornerback on his side, the other safety being responsible for himself and the 2 other secondary players on the other side. The 3rd zone is made up of the remaining linebackers and defensive linemen. By simplifying this defense into these 3 zones, younger players can focus on learning that part of the coverage as opposed to learning an entire defense. This is why the 4-2-5 makes for a great defense at the youth levels. The 4-2-5 is also great for safety-linebacker hybrids that may be too small to play linebacker but not fast enough or good enough in coverage to be a Safety. The 4-2-5 defense gives opportunities for these types of players to excel.

The 4-2-5 defense is run to allow 6 players play in the box. For that reason, the gap-principles of this defense make it strong against the run. Having 5 defensive backs allows the defense to defend the flats and force the ball to the outside of the field where faster safeties and cornerbacks can make plays on the ball.


Defensive Linemen


Defensive linemen in a 4-2-5 defense have the same roles as they would in a 4-3 defense. Two defensive tackles will be used and they will be lined up fairly wide, in the 2 or 3-technique between the offensive tackle and offensive guard. The defensive ends will also be lined up wide, in the 5-technique, shaded to the outside of the offensive tackles. If there is a tight end, they will be shaded off of them. The reason for this is to allow the defensive ends to face less double teams on the outside of the offensive line.

Defensive tackles in this defense are primarily used to take up blockers on the interior and stop the run. As opposed to a 3-4, a 4-3 means that the tackles don’t need to be as big but should be quicker footed than your standard nose tackle. The tackles will typically be responsible for the A gaps and sometimes the B gaps on stunts. These tackles will allow for the linebackers in a 4-2-5 defense to make plays in the middle of the field.

Defensive ends in the 4-2-5 defense are going to be your fastest defensive linemen. These linemen don’t need to be very big but must be able to consistently beat tight ends or offensive tackles. These defensive ends are pure pass rushers. These defensive ends should also be able to play contain on the quarterback as well as play the run on outside rushes.


Linebackers


The 4-2-5 defense utilizes 2 linebackers, a MIKE and a WILL linebacker. The MIKE linebacker will traditionally be your classic middle linebacker. This means that they will be expected to come down to make plays on inside runs. The MIKE linebacker is typically expected to fill one of the inside gaps, opposite of the defensive tackle. If the tackle is shaded inside the guard, the linebacker is responsible for the B gap. If the tackle is shaded outside of the guard, the linebacker is responsible for the A gap. The linebacker may also be tasked with being responsible for the running back if the play is a pass.

The WILL Linebacker will be the more athletic of the two linebackers and will typically be faster and better in pass coverage, as they may be expected to drop into coverage or match up against the tight end or running back. The WILL linebacker will also be expected to rush the passer on blitz packages. Having two inside linebackers that are capable of playing the run allows the 4-2-5 to be effective and forcing the ball to the outside. Having linebackers that are capable of dropping back into coverage allows the 4-2-5 defense to get creative with different schemes from the defensive backs such as rushing the nickelback or strong safety.


Cornerbacks


The two traditional cornerbacks will line up on the outside receivers on either side of the formation. These corners will absolutely need to be fast enough and strong enough in pass coverage to keep up with the receiver they are matched up on. In a defense that is predicated on forcing the ball to the outside, it is important to make sure that your corners aren’t being burned or this defense won’t be able to work at all. Cornerbacks on different sides will usually have different coverages called by the safeties. Sometimes the cornerbacks will be in a zone coverage and be asked to defend the flats as opposed to stay man-to-man on the receiver, if there is a safety over the top. The 4-2-5 defense could be great for younger cornerbacks that are getting introduced to the defense. In the 4-2-5 these players will be asked to learn certain coverages within the formation as opposed to the entire defense.


Nickelback


The nickelback is a type of cornerback that comes onto the field during the 4-2-5 defense in replacement of a linebacker. This allows the defense to become quicker during passing situations. The nickelback will typically mirror the strong safety on the other side of the formation. In a zone coverage, the nickelback will key on the outermost player on the line, either a tight end or offensive tackle. They will usually cover the flats in this coverage. In man-to-man coverage, the nickelback will key on the receiver they are lined up against. This is usually going to be a slot receiver. The nickelback is also referred to as a slot cornerback. These cornerbacks may not be as fast as the corners that play on the outside. Instead, these corners are typically smart players that are strong open field tacklers. The corners should be able to make quick reads when they are mirroring the slot receiver. Certain schemes may call for the nickelback to blitz the quarterback as well. Some examples of NFL nickelbacks include Chris Harris of the Denver Broncos or Justin Coleman of the Seattle Seahawks. If you have a cornerback on your roster that might be struggling on the outside, consider moving them to a nickelback role.


Safeties


Safeties are arguably the most important part of the 4-2-5 defense as they are responsible for providing help on the outside wide receivers or covering the flats. The two types of safeties that are used are the free safety and the strong safety and both play very different roles in the 4-2-5 defense.

The strong safety is going to be that aforementioned linebacker-safety hybrid. This player is going to be expected to fulfill a lot of the responsibilities of a linebacker in a 3-4 or 4-3 defense. The strong safety is responsible for calling the coverage for the defensive backs on his side of the field. This safety can blitz, defend the flat or match up man-to-man on a slot receiver or tight end. The strong safety should also be expected to play the run if need be. In many regards, this safety is similar to the nickelback.

The free safety is going to play back and add over the top help on the #1 wide receiver. The free safety will function as more of an outfielder on pass plays and will almost always be lined up outside of the box. This safety needs to make quick reads based on the break made by the #1 wide receiver and may be responsible for the number 2 wide receiver. The free safety must also be watching the quarterback and the alignment of the offense to determine whether the play is a pass, a play-action, or a run, and act accordingly.


How to beat the 4-2-5 Defense

The 4-2-5 defense has been used more and more as teams are implementing more pass-catchers into their offense and playing a more spread style. This defense takes a player out of the box and puts in an extra defensive back. While the defense is faster in this scheme, they are also smaller than typical 4-3 and 3-4 defenses. This leaves the defense susceptible to a power running game from the offense. A strong running back can exploit the undersized defense. A two tight end formation often indicates a pass but can also be used in the power running game, which could lead to deception of the defense.
