- The 49ers may go with two unseasoned guards this year. They have been using fourth-round rookie Spencer Burford exclusively as their first-string right guard, Eric Branch of the San Francisco Chronicle notes. If the Texas-San Antonio product can stick at this position, it could relocate two-year San Francisco right guard starter Daniel Brunskill to center, where he is battling veteran backup Jake Brendel to take over for Alex Mack. Buford is vying to join Aaron Banks as a guard starter. The 2021 second-round pick logged five offensive snaps as a rookie but looks to have a firm grip on the 49ers’ left guard gig in camp.
