Pro Football Focus has continued ranking all 32 players at each position, with the center position today. For the San Francisco 49ers, the offensive line is a major talking point for fans and analysts. While the sum of the parts of the line makes it a middling group, Trent Williams does the heavy lifting at left tackle.
Colton McKivitz is a good return on investment for the 49ers at right tackle. Dominick Puni was excellent in his rookie season. Aaron Banks had an up-and-down season but departed for Green Bay, leaving an opening at left guard.
