The Raiders have made some major changes on their offensive line, but they will make sure their left tackle will not be going anywhere for a while. They agreed to terms with Kolton Miller on an extension Tuesday, Jeremy Fowler of ESPN.com reports (on Twitter).

Miller agreed to a three-year deal worth more than $18M annually, per Fowler, who adds the three-year veteran will receive more than $42.6M fully guaranteed. The contract will end up averaging just north of $18M per year, Tom Pelissero of NFL.com tweets. The agreement locks in Miller through the 2025 season. Miller’s rookie contract, including the fifth-year option, ran through 2022.

This marks the first extension handed out to a member of the 2018 draft class, which became extension-eligible in January. The Raiders had a Miller extension in mind for a bit now, and they will take care of their first draft pick of the second Jon Gruden era. After trading down with the Cardinals in a deal that sent them ex-UCLA quarterback Josh Rosen, the Raiders took Rosen’s blindside Bruins protector at No. 15 overall. The Raiders’ pick worked out, with Miller having started 46 games in three seasons.

Las Vegas’ Miller decision comes after the team surprised most by gutting its offensive line. The Raiders traded Pro Bowlers Rodney Hudson and Trent Brown and also dealt its longest-tenured O-lineman, Gabe Jackson. While the team still opted to bring back Richie Incognito and Denzelle Good, Miller is now this O-line’s unquestioned anchor.

Pro Football Focus has not viewed Miller as a high-end tackle just yet, though it did assign the 25-year-old blocker his best grade last season. He ranked a career-best 34th among tackles in 2020. While Miller has helped Josh Jacobs to back-to-back 1,000-yard rushing seasons and been present for consecutive Derek Carr top-11 QBR campaigns, this extension marks a bet in further Miller development.
