I guess the question comes down to how the Steelers see their roster, and they may see it differently than us. The Steelers will lie to themselves, and then believe their own lies. How the hell else can you explain the OL fiasco with an old QB last year? The problem is not with the players, it is with the decision makers who put them in positions in which failure was too likely.
So while I agree with Sask about Davis, I can see the Steeler brass thinking, "well, we have Alualu and Tuitt coming back, we'll be good there and can compete." Maybe they'll be right and the fact is they are more often than not. But after the OL mess of last year...
