49ers may not need to look far to find 1 new starting OL

An overhaul of the offensive line looks to be one key priority of the San Francisco 49ers offseason.

Left tackle Trent Williams is expected to return and right guard Dominick Puni acquitted himself well in his rookie season. Center Jake Brendel and right tackle Colton McKivitz are also under contract for next year, but it wouldn’t be a huge surprise if the 49ers looked to upgrade both of those spots.

The only spot wide open entering the offseason is left guard, where starter Aaron Banks is slated to hit unrestricted free agency. If the 49ers plan on letting Banks walk, they may not need to look far to find his replacement.

While the team would ideally throw a bunch of money or draft capital into the offensive line, they have other areas of their roster that need improvement which means finding cheaper, non-draft related ways to fill OL spots is imperative.

Two names on the 2024 roster jump out when considering what the 49ers could do to improve at left guard: Ben Bartch and Spencer Burford. They were the two backups for Banks this season and they both acquitted themselves well at the position in limited playing time.

Bartch, an unrestricted free agent, has been a work in progress since the 49ers signed him off the Jacksonville Jaguars practice squad in the middle of the 2023 season. His move up the depth chart this offseason is a sign that the progress has been good. He was very good in his start against the Buffalo Bills in Week 13, and in 34 total pass blocking snaps this season he gave up just one pressure and no sacks. Bartch might have finished the year as the starter had he not suffered a high ankle sprain in Week 14.

The 49ers wouldn’t likely have to break the bank to bring Bartch back, and there’s a real chance he’d prove to be their best option at left guard.

Whoever gets the starting job to open training camp figures to have some competition, and Burford would provide that for Bartch (and whoever else the club deems as a starting candidate).

Burford struggled on the right side, but he largely played on the left side in college and it appears the swap helped him as a pro. Off the bench this season he had some ups and downs while moving around the line, but overall looked like he could be an effective player if given the chance for regular reps at left guard. He gave up one pressure in 38 pass blocking snaps at that position per Pro Football Focus.

The 49ers could prioritize left guard more heavily this year and bring in a starting-caliber free agent or a high draft pick. Given their other needs, finding cheap solutions nearby may be the better route. Bartch and Burford both flashed enough to at least be in the mix, and the 49ers may be wise to give both a long look as they aim to revamp their offensive front.
