Having RB on the books dosen`t mean any of them are good enough for to start every week. 2 of them are nearing the end of their careers and can barely last 90 minutes, and we seem to just alternate between them, and Patterson dosen`t seem to be good enough when fit to nail down that slot.. I`d say its harder to find the right player to sign as a backup player that knows they`ll most likely be sat on the bench every week rather than signing a player that would be expected to be a starter for that position.
I agree we need cover at LB, but we need to nail down a starting RB too.
