No hurry, they still have Henderson and Funk as #1 and #2 and they have Jones and Anderson. Webster wasn't going to make the roster because of Tutu, Jackson and Skowronek. This way he can join Rams North, i.e. Detroit. He's as good or better than anyone they have right now and he's a known quantity with Goff and Holmes.
They just signed Anderson so I don't see them signing another RB unless they have another injury. Because of the long term uncertainty of Akers I see them drafting another RB next year.
