49ers Offensive Line

Left tackle Trent Williams is awfully good at football. Left guard Laken Tomlinson is good at football, too.

The rest of the Niners offensive line? Not so much. At least not in Week 9.

Despite the Cardinals being without defensive tackle J.J. Watt, who’s out with a shoulder injury, they still managed to muster five sacks on quarterback Jimmy Garoppolo. And while he bears some blame for taking a few of those takedowns, it was painful enough to see EDGE Markus Golden knife through the interior on one sack, making center Alex Mack and right guard Daniel Brunskill look bad, then capitalize on two more sacks off the edge.

Additionally, right tackle Mike McGlinchey exited with a knee injury, which confusingly led to Kyle Shanahan inserting offensive lineman Tom Compton in his stead instead of the promising rookie, Jaylon Moore.

Compton allowed three sacks on the game, by the way.

If there is a bonus, at least San Francisco averaged 4.5 rush yards per carry with running back Elijah Mitchell.

But considering he only got eight carries, and the 49ers had only 39 rush yards in total, it doesn’t matter much.

Grade: D-
