I'd disagree. When you get a ton of new talent on a defense (Joseph, Smith, Irvin, Jones, etc.) You never know when things are just going to spontaneously "click." It's quite clear that the Raiders D took a big step forward today after a couple of them (Amerson, Smith) broke out last week. Also, keep in mind the Saints and Falcons are two good offenses and thats partially why the Raiders have been statistically struggling on D.
