Should we be concerned about the defensive line?

[MTK]

At this point in free agency I thought we would have upgraded our defensive line a bit more, at least from a pass rushing perspective.

Griffin is known as a run stuffer at DT so he's not likely to add much in way of pressure.

Daniels doesn't seem much of a threat to log more than 5 or 6 sacks at best, and we have holdovers like Wynn and Upshaw who haven't exactly torn up the NFL with their pass rushing skills.

I'm sensing that with the addition of Washington at strong side LB and by sliding Arrington over the the weak side that Williams will be aggressive with the LB's to compensate for the lack of a strong pass rushing threat from the DE spots.

Does this scare anyone just a bit? We went into last season with the same idea and we all know how that ended up.

I know that the difference maker here could be Williams and his schemes. But still, a part of me is a little concerned.
