Will the Steelers D get exposed this year?

I mean their p D is borderline bad, they'll lose at least 1 of their 2 top corners and putting William Gay as your starter is insulting the other teams WR. Sure they drafted some corners but none were highly touted coming out of college. Meanwhile their division rival ravens grabbed perhaps the most talented CB in Jimmy smith and the bengals got both a super freak in AJ green and a very capable qb in Andy Dalton. All I'm saying is I think if the steelers don't upgrade their secondary they might spend a few seasons being 3rd in their division.
