The Ravens don't like giving up comp picks so you not going to see them making a push for players whom are not cut by their previous team. The Ravens may not at this moment consider the Safety position as much of a concern as we fans tend to believe or think. I can see them going after a safety like Dashon Goldson or Micheal Griffin(if cut). Other safeties like Stevie Brown,Kendrick Lewis, Louis Delmas and etc could be potential targets but probably around June only if they still around.
