ESPN Projects 49ers Could Sign Joel Bitonio to Pair With Trent Williams

Aaron Schatz of ESPN projected that the San Francisco 49ers could add veteran guard Joel Bitonio to line up at left guard next to 12-time Pro Bowl left tackle Trent Williams, a move Schatz called capable of producing "the best duo at those positions in the entire league." The projection lands ahead of NFL free agency opening March 11, 2026, and immediately frames the 49ers’ offseason as one centered on the blind side of the line and Williams’ unresolved contract.

Bitonio enters the offseason as a 12-year Cleveland Browns veteran and a seven-time Pro Bowl selection with first-team All-Pro honors in 2021 and 2022. He renegotiated with Cleveland for a one-year, $15 million deal in 2025, but market evaluators project a lower open-market figure: Spotrac estimates roughly "$12.9 million a year" as his free-agent market value. Sources note both numbers without confirming which, if either, will be the 2026 contract Bitonio actually commands.

The analytics case for Bitonio is concrete. Schatz highlighted that "He ranked third among all guards with a 96.4% pass block win rate last season, and his run block win rate of 72.3% was above average." That combination of pass-protection dominance and above-average run-blocking performance is the justification for pairing Bitonio with Williams on the left side, particularly for a 49ers offense that has shown cracks in running efficiency.

San Francisco’s roster context makes the fit plausible. Left guard Spencer Burford is set to become an unrestricted free agent, creating a vacancy on the left interior. Trent Williams, age 37 and a fixture at left tackle, remains in active contract talks. General manager John Lynch has expressed optimism about resolving that situation, saying he has "a great deal of confidence" in finding a solution to Williams’ contract dispute. Bringing in a veteran like Bitonio could be both a tactical upgrade and a signal to Williams that the 49ers are doubling down on the left side.

The strategic rationale extends to the run game. Running back Christian McCaffrey posted a 3.9 yards-per-carry average last season, the lowest of his San Francisco tenure, and analysts have flagged offensive-line investment as central to restoring a more physical, run-heavy identity. Bitonio’s pass and run metrics, plus his reputation as a "savvy technician," are cited as reasons a short-term, one-year veteran signing could help the 49ers maximize a championship window.

Significant caveats remain. Bitonio turns 34 entering the 2026 season and Williams is 37, raising durability and age-related risk if the franchise builds the blind side around two veterans. Price and term are uncertain given the differing $15 million renegotiation figure and the Spotrac projection, and the club’s left-guard plan is contingent on how Williams’ contract and 2026 cap realities evolve. Alternatives such as Alijah Vera-Tucker were also mentioned as younger options if the 49ers prefer a different path.

With free agency set to open March 11, the 49ers’ next moves on Williams’ contract and the left-guard market will determine whether Schatz’s projection becomes realistic roster strategy or one of several speculative scenarios aimed at preserving San Francisco’s title window.
