Lets talk about the new NFL. Not the old league where it was about running the ball and stopping the run. Its all different now.
As far as I'm concerned, our FO, in both free agency and the draft, should focus on the two things that help you win more than anything else in the "New NFL".
1. Protecting your QB
1B. Getting after the other QB
The rules today make it so difficult to play defense and so easy to throw the ball, these have to be our priorities. You can't reroute WR's, you can't hit them after they catch the ball (unless you use geometric precision), You can't hit the QB after he throws the ball, You can't hit him before he throws the ball in any place other than about a 1 square foot space from the waiste to under the shoulder blades.
So I would say that looking for pass rushers and pass protectors has to be our focus. Even great corners can't cover well enough given these new rules. We saw a great (at least by today's standards) defense like SF get lit up by friggin Joe Flacco.
All you can do is score a lot of points, and create havoc on defense for their QB. We have learned from our own experience, defense is only as good as their ability to get after the QB.
My 2 cents.
