The 49ers have the ninth-worst offensive line in the NFL

The biggest and possibly only weakness on the 49ers roster is their offensive line.

Every other position group stacks if healthy. The 49ers simply don’t like to invest much in offensive linemen other than difference-maker Trent Williams. Their philosophy is to invest in attacking players who touch the ball, and not in players who just block.

And because of this philosophy, the 49ers have the ninth-worst offensive line in the NFL, according to Pro Football Focus.

“While the 49ers offensive line features a future Hall of Famer and perhaps the best offensive lineman of recent years in Trent Williams, those around him have failed to make an impact thus far,” PFF analyst writes Zoltan Buday. “The rest of the offensive line consists of career journeymen, such as center Jake Brendel and right guard Jon Feliciano, or young offensive linemen that the 49ers hope can improve in 2024, such as Aaron Banks and Colton McKivitz.”

That’s a brutal assessment. And McKivitz isn’t even young — he’ll be 28 in August. He’s in the middle of his prime and he’s still a liability. I seriously doubt the 49ers expect him to improve. And Banks is likely entering his final season with the team, since he’ll be a free agent next year and the 49ers aren’t spending money on guards.

Without Williams, who misses at least a few games every season, the 49ers have perhaps the worst offensive line in the NFL. You’d think they’d want to improve it, keeping Brock Purdy upright and healthy for as long as possible. But head coach Kyle Shanahan never changes his offensive philosophy.
