There is still a month until the NFL Draft, and the Ravens likely have almost all of their potential targets ranked accordingly on their board.
In the meantime, they still need to add a few more veteran playmakers because of the uncertainty surrounding the draft and the teams selecting ahead of them.
The Ravens are still looking for a tight end and/or another receiver, despite the signings of Michael Crabtree and John Brown. However, this does not mean the team will sign a veteran player prior to the draft.
