The next most likely position is WR with Meacham, Bowe, Ginn and Rice although with the current state of the roster I cannot see them not grabbing a CB with their first pick.
For whatever reason this isn't popular around here but makes the most sense to me if the top CB's are gone. I've argued and no one can tell me who will start next to Colston next year. And as long as that's the case, WR in round 1 is a logical choice. And I'd be happy with any of the WR's listed above.
