Andrew Thomas – Georgia

The replacement for Isaiah Wynn with the Bulldogs, Thomas has played both right and left tackle in his collegiate career. The 49ers have long since valued versatility and Thomas’ familiarity with both spots would make him a prime candidate for the swing tackle spot as a rookie.

Thomas could serve as the safety net should Staley or McGlinchey get hurt before moving into a starting role after his rookie year.
