Far too many people are laying the blame on the coordinators. Well, players were getting open in the passing game, and the running game wasn't able to open holes. The defense is loaded with players who, for one reason or another, aren't really ready to be starting on top defenses.
It's a personnel/talent/experience/execution problem for the most part. Blaming the coordinators is a cop out.
