Weeden and Bradford didn't play that well against the Saints. No need to blow things out of proportion....until that Giants game it looked like they were getting better on D. Then Ellerbe, Kikaha and Swann all got hurt at the same time and you can't play good D with guys like Hawthorne and Browner on the field full time. Not like they would be great otherwise but they'd be like #25 or so and hanging in games like they did earlier in the season.
Too much talent on that D to not turn it around at least somewhat. Getting rid of Ryan's crappy zone blitzes should be good for at least a couple more third down stops a game.
