An expert thinks the 49ers’ offensive line could dominate the league in 2026, despite recent challenges. Trent Williams, the third-highest-rated left tackle, is still the linchpin of the unit, while Jake Brendel, expected to leave the Niners’ roster, faces scrutiny over his career. Right guard Dominick Puni’s slow start hints at potential upgrades, and right tackle Colton McKivitz’s struggles reflect broader team dynamics. Analysts predict a shift in talent pipelines, with free agency reshaping the outlook. This season’s performance hinges on depth and adaptability, raising questions about how the Niners will balance tradition with innovation.
