Williams penned a six-year, $138.06 million extension after being traded to the 49ers from Washington in 2020. Last year, this contract was restructured, converting $18.23 million of his base salary for 2023 into a $30 million signing bonus proration through 2027 (still on the hook), freeing up nearly $15 million in salary cap space for the team.
The 36-year-old 11-time Pro Bowler is set to bank $20.8 million in 2024 and $23.35 million in 2025. However, all of the guaranteed money has already been paid out, and several offensive tackles have eclipsed him in terms of average annual earnings.
Williams is most likely looking at the four-year, $112 million agreement that the Detroit Lions handed out to offensive tackle Penei Sewell in April as the benchmark. Even though he just turned 36 years old, he still believes he's the best offensive lineman in the league and has started 58 games over the last four seasons for the 49ers.
Williams had seriously considered sitting out regular-season games after being left off the 49ers' initial 53-man roster, marked on the reserve/did not report list. However, with contract negotiations nearing completion, both he and the team can now turn their attention to finishing what they started in last season's Super Bowl pursuit.
