I ventured over to Grantland since Bill Barnwell loves us so much and came across this article.

I was happy to read this section:

Webb played virtually every defensive snap in the Week 3 contest between these two teams, while Smith was in on 82 percent of the defensive plays. Smith didn't play a single defensive snap last week, with his spot in the rotation taken by Chykie Brown, but the more notable replacement is Corey Graham, whom you may remember running a Peyton Manning interception back to the house last week. Graham was an elite gunner on special teams for the Chicago Bears whom the Ravens signed this offseason to serve as their kick- and punt-coverage dynamo, but the injuries have pushed him into a regular role in the defense. Graham didn't play a single defensive snap in Week 3
Obviously going from Webb to Williams is a steep downgrade for covering the #1 receiver. However, we've gone from Cary Williams and Jimmy Smith in the #2 and #3 spots to Corey Graham and Chykie Brown which I think is an upgrade in both slots. I think Corey Graham's play has been speaking for itself and then I saw this over at ProFootbalFocus the other day "Nickel cornerback Chykie Brown has 0.83 Yards per Coverage Snap, which is the fourth-lowest in the league, behind Bradley Fletcher, Lardarius Webb and Nate Clements".

You can also factor in that Gronkowski is out and it wouldn't be crazy to think that maybe our secondary will play better than Week 3.
