Think more left and right safety than free and strong. Jenks is definitely gonna be over the top more . Harper will be in the box more. But their roles are a lot more interchangeable in SpagNOLA D. As the NFL continues to grow more pass happy this trend increases as well.
Ive been saying something along these lines all season. The NFL is making the league more pass happy. And right now the offense gets a big boost from that. But DB's are going to become more athletic and versatile, DCs will adapt and the competition will even itself out again. Its going to be fun as hell to watch defenses evolve over the next decade. I've always been a bigger fan of watching defense more than offense. And i still very much am.
