Outlook: If the Ravens will part ways with McGahee, they'll need to find a strong insider runner to replace him. This year's draft class doesn't have major headliners outside Alabama's Mark Ingram, so the value of this group of backs is in the middle rounds. Williams, who had a private workout with the Ravens, could be taken as early as the second round. Vereen, a third-round prospect, proved to be a more powerful in between-the-tackles runner than his predecessor Jahvid Best. Helu, who is projected to go in the fourth or fifth round, impressed scouts at the Senior Bowl with his size and speed. John Clay, Carter and Ridley are all over 220 pounds and can take on tacklers. Ridley, a fifth-round prospect who scored 15 touchdowns last season, spoke to the Ravens at the NFL combine.
