If poe, hightower, Glenn, cox, and barron are gone the steelers most likely will pick an o lineman. I just don't think it should be Adams. He's not any better than the guys we have. I'd prefer them picking zeitler, or worthy as a nt based on who was left on your mock.
Of course I'd prefer Detroit to let old habits die hard and pick a wr in the 1st, so we can snatch hightower.
