2. Jurrell Casey is perfect to play DE in a 3-4 defense
While new LA Chargers head coach Brandon Staley has not fully committed to what scheme defense the team will run in 2021, it is important to note that every team he has coached for at the NFL level has played a 3-4 defense.
There is a good chance that the Chargers switch over from the 4-3 defense as long as they get the necessary pieces to complete that switch. Jurrell Casey would be such a perfect fit in a 3-4 defense and would make the fit seamless.
There are two things the Chargers need to make this switch. They need another traditional outside linebacker. Uchenna Nwosu will be just fine as an OLB but they need someone to play the other side. Joey Bosa could help some, but they need a traditional OLB.
They also need a defensive end. A 3-4 defensive end is different than a 4-3 defensive end as run defense is more valued than pass rush. And as we already mentioned, the team’s options to be that other defensive end are limited as they are not good against the run.
Casey just deepens the defensive line and gives them a complete outlook. They get a guy who can be really good against the run and still hold his own in the pass rush without having to trust in Jerry Tillery to do too much and (probably) get exposed.
