While quarters coverage continues to be one of the more popular adjustments to defend RPOs, offensive coordinators have taken advantage of deficiencies in the flats. So, integrating trap checks at the line of scrimmage is a simple adjustment that not only takes away the quick screen game by allowing a cornerback to “trigger” on a route to the flats but also protects any vertical by the #1 wide receiver with leverage and help from the safety. Milton High School (GA) defensive coordinator Pete DeWeese details how he trains the corner and corresponding safety to play trap coverage efficiently against the most common RPO concepts.

Every coverage has a weakness. Offensive coaches know and understand what those weaknesses are and how to exploit them. As offenses continue to reinvent the wheel and add RPOs to their playbook, it seems like most good defenses are scaling back. Utilizing sound coverage principles and simple, time-tested, coverage checks are still a great way to defend most any offense.

Quarters coverage is easily one of the more popular coverages at all levels of football, but good OC’s know how to attack quarters teams. The simple trap check is a great addition for any quarters team. Trap allows a cornerback to “trigger” on a route to the flats while protecting any vertical by the #1 WR with leverage and help from the safety. Trap allows us to maintain our Cover 4 principles that we like versus drop-back-pass concepts while easily adjusting to quick game concepts that offenses like in most down and distance situations. 

Defend the Flats

One of the biggest flaws of Cover 4 is the ability to defend the flats. Most defensive coordinators are going to place an emphasis on stopping the run. While Cover 4 does add safeties to the box to assist with the run game, the defense is giving up the flats if they keep their LB’s or APEX players attached to the box to defend the run.


Widening the LB’s/APEX defender gives the offense a potential numbers advantage in the box and makes the defense more susceptible to the run game. With so many teams using some form of RPO, defenses are often having to pick their poison and remain vulnerable in one phase or the other. Using a Trap check in your quarter’s coverage principle will help your defense handle quick game concepts while remaining strong against the run.

What Is Trap?

Our Trap check is an easy way of marrying your Cover 4 with Cover 2 principles while protecting your outside linebackers and run-game integrity. Trap is safe against four verticals and safe against 2x2 quick game staples like fade/out, smash, or all hitch. 

Teaching Trap

The basics of the Trap check are easy to install and implement. I like to start by teaching the concept and then training them on when to utilize the check. The concept starts with an understanding that we want to maintain inside leverage and “zone eyes” in the coverage.

This Trap check is an effective check that can help your defense if you do not already have a version in your system. As offensive teams continue to implement RPO schemes into their offensive game plans and read defenders at each level of the defense, I think that Trap can help to alleviate some of the threat caused by many 2-Back and 2x2 RPOs. Hopefully this article has given you some ideas as to how you can incorporate this into your defense.
