Davis is still very young and has elite athleticism. Staley also looks like he hasn't hit his ceiling yet. Iupati is already a great player and Goodwin likely still has a year or two of tread left on his tires.
My take is this.....let these guys have another year in Harbaugh's system and another year with this terrific coaching staff before calling for drastic changes. I do think the team will sign a vet OG for depth at least and will probably draft at least one OLman so although I can understand the proposal, I think it is a little too early for that conversation.
One last thing....I would be shocked if the Niners spent a first round draft pick on an OG...because they have always invested so much money and high draft picks on the OL already. I can see them using a second rounder on a guard though.
