The right guard situation is in flux and we might not know the complete answer until Monday Night Football lineup announcements.
The San Francisco 49ers offensive line appeared set to be a significantly improved group in 2016. The team welcomed back Anthony Davis, saw Trent Brown start to emerge as a force at right tackle, signed Zane Beadles into a scheme that better suited his skills, and moved up into the first round to grab guard Joshua Garnett. Although Garnett did not claim a starting role with the return of Davis, the depth was looking very solid.
Of course, this optimism was predicated on some semblance of stability along the line.
