I for one don't think we really have any quality backs on the team. Zeke and Freeman are both washed up, Rico is ave. a 3rd stringer at best, DV is a tiny gimmick back whom they won't ever give a real shot at being the man. Davis just doesn't seem to have it and the rest are just camp bodies.
No, I don't think they had any real shot at signing one of the top FAs, they didn't have any $ to spare knowing what they needed for Dak and CDL. Yes, they surprisingly passed on drafting one, although they way the draft played out I understand why they did.
I agree it's not very likely that we trade for one at this point, but I disagree that we shouldn't. Regardless of how much the O-line is improved, a RB who is solid in all phases is still needed. You have to be able to pound it at times, to make yac, to move the sticks and to pass block. I have seen it time after time, where a back up or an ave RB struggles in one phase or another, even behind a good/great O-line.
There are multiple teams with solid RB's down on their depth charts who are in need of o-line and DB help. We have a surplus of decent players at those positions. Not saying they're great players, but they are decent and teams are and will be getting desperate, which drives up their value. I think it would be wise to take advantage of that and go get a missing piece of the puzzle. Why wait until there is a chance of bidding war for the one you want?
