Jeeeeeezus. Some people are hard to please. The defense flat-out balled. If not for AJ Green (you remember him, right?) and a thankfully limited number of Gio Bernard snaps, we would have virtually shut them down. We made Dalton look like a 50 QBR player, not a 112 or whatever it is lately. We shut down Green-Ellis and we forced a serious number of 3-and-outs. Not to mention the turnovers and the game-winning safety.
That was a terrific defensive performance. Any other opinion is frankly ignoring what stares you in the face.
I agree they played real good for how long they were on the field and against a really good offense. Being an older guy I remember great defenses of the past so I wouldn't call their performance great. They give up too many third and longs. But like I said in the other post, the NFL has changed, you can't completely shut down anybody anymore.
