According to Gruden it was obvious 2 man that was the problem.

Its not the scheme. All schemes are vulnerable to something. There is either an area or numbers mismatch in anything but the most vanilla scheme. And the most vanilla scheme is vulnerable to offenses forcing it to do something its players can't do.

The problem is construction. Everything Capers does is to prevent big plays and get turnovers. To do that with his schemes he needs pressure. There ain't no pressure. Even when blitzing there is not immediate pressure.

If you are going to play this way (and not having a pass rush is kinda limiting) you need to creep up and play tight coverage, risk a big play, and give your front and blitzes time to GET pressure. They have tried bleeding slowly and they are close to passing out anyway.
