Tackles: Joe Staley, Trent Brown
10-year veteran Joe Staley is a mainstay on this offensive line, he is the leader and will be the starting left tackle for the 49ers until he retires.
49ers tackle Trent Brown has put together a solid training camp this offseason and showed some good play against the Texans in Week 1 of the preseason. Brown has earned his starting role.
Guards: Joshua Garnett, Zane Beadles
Garnett showed some violent play against the Texans, proving he has what it takes to make the jump up to the starting role. Although guard Andrew Tiller has played well, the 49ers should make the move to start their 2016 first-round selection in Garnett.
Beadles looks to be more comfortable playing in a zone-run system that he thrives in. He looked fluid in Week 1 and has shown he has earned his starting spot.
Center: Daniel Kilgore
Kilgore will retain his starting role as center for the 49ers. He is the best center on the team and has shown no signs of letting up. Backup center Marcus Martin has not threatened Kilgore in any way with his play.
Kilgore will remain the starter.
