What's the better defensive team play this week?

I would say the Browns would be your best choice against the Ravens bad offenese, but Flacco and the the Ravens offense did well this last week...and the Browns defense is notoriously bad. I like the Cardinals. The Rams are definately improved from the beginning of the season, but they aren't great...and I think Arizona's defense is slightly underrated (don't get me wrong, I'm not saying they're great by any stretch of the imagination).
