I don't know, I mean I watched the Vikings host the Redskins in Minnesota last week, and they barely got by them, winning 19-9. They let the Redskins hang around until the 4th quarter when they finally put them away. And this is the Vikings offense, one of the top offenses in the league.
I'd say we did pretty well, offensively, all things considered. And although the Redskins have a crappy record, and are statistically in the bottom third defensively in the league, they're still able to pose big problems...even for teams with "good" offenses.
