Our base is actually a 4-2-5 and we occasionally run a 4-3, not the other way around. It’s why if you
look at our depth charts we list 2 LBs and 5 DBs. Our nickelbacks are the closest we have to an LB/DB hybrid.
And I wouldn’t say that we have much commonality with the 3-4 given how we run our defense. Coughlin was undersized for the position, but Rossi and company moved him to that position because they felt he’d be more effective closer to the line. Mafe is 6’4” 265, which is the same weight as Chase Young. They’re occasionally in a 2 point stance, but it’s much more common to see them in a 3 point one if you roll the tape. The biggest thing with OLBs in a 3-4 is that they will frequently drop into pass coverage as you disguise blitzes by rotating where it’s coming from. Our DEs definitely dont do that.
