Ben Bartch just re-signed, but there’s another player on the roster who might be groomed to take over Aaron Banks’s spot at left guard
SANTA CLARA – Ben Bartch, a potential starting offensive lineman, re-signed with the 49ers on Monday, two weeks ahead of the NFL’s free agency window. Whether or not Bartch vies for a starting role, the 49ers sought that option as they face the prospect of losing left guard Aaron Banks and swing tackle Jaylon Moore in free agency.
