With Trey out move to a 3-4

[Au165]

The OP concept is not really football sounds. A “3-4 nickel” is a 4-2-5 or a 3-3-5 with an over or under look. No one is using corners or stack linebackers to set the edge. OP may potentially be thinking of like a dollar set which is 3 down lineman and 2 linebackers with 4 CBs similar to dime. You can go here in obvious passing downs but it has to be specific situations because the lack of matching hat count in this formation can lead to explosive runs.
