I think the Steelers definitely need a left guard. Ones that come immediately into my mind are Warmack and Cooper. Both can be day 1 starters for the Steelers. I also like Barrett Jones, Kyle Long, Alvin Bailey and Travis Frederick (although he can be a center too). If we drafted Warmack, we would have the best interior offensive line in the NFL with Pouncey and DeCastro. Cooper would also be a perfect fit with the new offensive zone scheme.
