From the stories I've read, Baltimore is willing to take a late first/early second rounder in exchange for Gaither. Why not offer to swap our first round pick with theirs and see if they'd be interested in that? That is equivalent to a late round pick and I'd even be willing to throw in a late round pick this year or mid round pick next year to get that deal done.
If we were able to do that, we'd be able to solve our LT problem. Then with the #25 pick, we could pick up Jerry Hughes/Sergio Kindle to fill the OLB hole and get our NT (Cody or Cam Thomas) with our second round pick.
At that point, it only leaves QB as a gaping hole. If OBD really likes someone like Skelton, Lefouever, etc., then take a shot at one of them in the 3rd round. Or at least if we were able to get LT, OLB and NT filled by the time we make our second pick, we can truly go BPA for the rest of the draft.
Of course this is all predicated on the Ravens accepting that offer, but I see that as a great scenario if we could make it happen.
