Sources — San Francisco 49ers, Trent Williams agree to $138M deal that makes him highest-paid OL in NFL history – ESPN

Trent Williams and the San Francisco 49ers have reached a six-year, $138.06 million deal that will make him the highest-paid offensive lineman in NFL history, his agency announced Wednesday morning.

The deal has $55.1 million in guaranteed money, Williams’ agency Elite Loyalty Sports tweeted. The contract also includes a $30.1 million signing bonus, sources told ESPN’s Dianna Russini.

The Niners also are pursuing a deal with free-agent center Alex Mack, a source told Russini.

Williams, widely considered the best available free agent this offseason, previously discussed deals this week with the Kansas City Chiefs and Chicago Bears, sources told ESPN’s Adam Schefter.

But Kansas City signed Joe Thuney and Chicago signed Germain Ifedi, paving the way for Brown’s historic deal to return to San Francisco.

The 49ers traded for Williams on the third day of the 2020 NFL draft, sending a fifth-round selection and a 2021 third-round choice to the Washington Football Team.

Upon Williams joining the Niners, the team agreed to add a clause in his contract that meant it could not tag him this offseason. Williams went on to stabilize the left tackle position in place of the retired Joe Staley, starting 14 games and returning to his previous Pro Bowl form in the process.

Williams, 32, finished last season with the fourth-best pass block win rate (93.6%) among offensive tackles, according to ESPN Metrics/NFL Next Gen Stats, trailing only Andrew Whitworth (94.2%), Duane Brown (94%) and Billy Turner (93.7%).

All of that came in Williams’ first season back after sitting out all of 2019 as he engaged in a dispute with Washington over the handling of his injury issues and his contract.

At the end of the season, Williams maintained that he hoped to re-sign with San Francisco but also acknowledged that he wanted to see what a premier tackle could get on the open market because players at his position of that caliber rarely make it that far into free agency.

Since entering the league as the No. 4 overall pick in the 2010 draft, Williams has started 133 games, earning eight Pro Bowl berths and a second-team All-Pro nod in 2015. His eight Pro Bowl appearances are the most in the league for an offensive lineman since 2012.
