One of Ayers, Wilkerson, or Heyward will be there at 30. Why do I have a feeling that we pick none of them? It would certainly fit in with the craziness of this draft so far...
My guess is Ravens were set on Smith, at the last second decided they wanted to do a late character check or something or that nature on him and passed on the pick to make sure of whatever they wanted to make sure of, risking that the Chiefs wouldn't take him.
