The San Francisco 49ers offensive line wasn’t good in Week 1 against the Carolina Panthers, but left guard Zane Beadles was a big problem, meaning he should sit in Week 2.

After losing 23-3 to the Carolina Panthers to open up the 2017 season, the San Francisco 49ers may want to make a significant change along the offensive line.

And that change is to sit left guard Zane Beadles and replace him with recently acquired Laken Tomlinson.

As a whole, San Francisco’s O-line wasn’t particularly great in Week 1. Quarterback Brian Hoyer was under pressure almost constantly, and the Niners never really got their outside-zone running game going.

Beadles was a primary issue, giving up six quarterback pressures during the game, according to Pro Football Focus (h/t Jennifer Lee Chan of Niners Nation). And Beadles’ 23.1 overall game grade was the worst among all guards, according to PFF’s Jeff Deeney:

Grades are still going thru review but Zane Beadles' 23.1 overall grade was lowest of any guard in Wk 1. Sack, hit, 4 hurries allowed #49ers — Jeff Deeney (@PFF_Jeff) September 11, 2017

Plays, like this whiff on an eventual sack of quarterback Brian Hoyer, justify the low grade:

The Niners likely didn’t intend Beadles to start this season, rather him serve as a utility backup capable of playing any position along the O-line. But that changed with second-year pro Joshua Garnett’s season-ending knee injury.

Tomlinson, who fell out of favor with the Detroit Lions last season, has the first-round draft-pick moniker associated with him. The No. 28 overall pick from 2015 was inactive for his first game with San Francisco, although one might expect that to change in Week 2.

It should.

The Niners travel to Seattle to take on the Seahawks, who are coming off a rough 17-9 road loss to the Green Bay Packers.

Whoever starts at left guard for San Francisco will frequently line up opposite defensive tackle Sheldon Richardson — the defensive force acquired by Seattle in a blockbuster trade with the Jets.

Richardson finished his first game with the Seahawks posting a respectable 77.2 PFF grade, finishing with four tackles and one quarterback hit.

Even without Richardson, Seattle’s front seven remains one of the best in the NFL. Meanwhile, the Niners offensive line looks like one of the worst in the opposite category.

Tomlinson may not be a serious upgrade, but it’s going to be hard to be as bad as Beadles.

Make the move, coach.
