Look, I'm hard on the guy more than I think a lot of fans are and when he does bad work like he did against Oakland, he gets my wrath like he should. But what I saw out of this defense today was not a problem with scheme, but a problem with players.
If you are looking for people to blame, look no further than the players themselves. We've seen it in every game this season, but players are looking around like they have no idea where they should be. Against the Bengals, Kendrick Lewis, Kyle Arrington, Rashaan Melvin and even Jimmy Smith were all torched at various moments or penalized for bad technique that allowed the Bengals to keep drives alive or score.
