It certainly couldn't be any worse. Watching our D last year was torture.......
I think you will see a tenacious hard-hitting defense that is well grounded in fundamentals. They will be aggressive and they won't give up. They will adjust well at halftime and during the game.
I don't expect to see any really tricky "brilliant" schemes though. Although I do expect the D to be prepared and not just play the base against everyone.
I also expect them to get burned some because the depth of talent isn't there yet.
