We already do this, and have for a while. It's all about alignment and assignment.

People get too caught up in labels and parroting coach speak (like "edge.") Instead, pay more attention to alignment and assignment.

Yes, there is a core philosophy to defenses. But there's nothing to stop 4-3 and 3-4 playbooks from crossing over and using elements of both in situational playcalling, or in the context of opponent preparation.

A lot of this, too is limited to personnel, which isn't a bad thing. As coaches you want to put your guys in the best position to make plays and win football games.

3-4/4-3... it's not a solution in and of itself. It's simply a tool used to get there with the players and ability you have to best execute the play.
