Trent Williams waiving to San Francisco 49ers fans.
The 49ers Joel Bitonio signing idea is on the table becauseESPN projected Cleveland Browns guard Joel Bitonio as San Francisco’s one free-agent move, essentially sliding the 34-year-old next to 37-year-old left tackle Trent Williams, assuming Williams and the 49ers come to an agreement.
That’s the appeal: plug a proven pass protector into a clear need. The skepticism: you’d be building the most important side of your line around two players deep into their 30s, at the exact moment Williams’ contract is already a live issue in Indianapolis-combine-season discourse.
The Trent Williams contract talks are active right now, and ESPN’s projection dropped as teams set their offseason boards, the timing matters because the 49ers’ left-guard plan is tied to Williams’ 2026 cap reality.
Key Points
ESPN projected Bitonio to the 49ers, citing elite pass-block win rate and an above-average run-block mark.
Trent Williams’ 2026 cap number (and ongoing talks) complicate any “win-now” spending around him.
The 49ers’ left-guard depth is a glaring question, but age and durability risk are real if the plan is “old next to old.”
ESPN’s 49ers Joel Bitonio Signing Projection: The Case For It
ESPN’s logic is straightforward: Bitonio can still play. Their win-rate data had him at 96% pass block win rate last season, and ESPN’s free-agent rankings called him a “savvy technician,” while also noting he’d be 34 entering the 2026 season and has extensive starting experience.
The fit next to Williams (if Williams stays). If the 49ers keep Williams, adding a steady left guard can help stabilize protections in Kyle Shanahan’s offense, especially on the backside of play-action and on long-developing concepts where interior leakage kills the call.

Why It’s Not That Simple: Trent Williams’ Contract and the “Old Left Side” Problem
Here’s the catch: Williams isn’t just “old” — he’s also expensive enough that the cap conversation is unavoidable.NFL.com reported Williams is set to carry a $38.8 million 2026 cap number and that GM John Lynch has had “good and substantive meetings” with Williams and his agent. CBS Sports also framed it as a situation that could, if unresolved, lead to Williams hitting free agency.
If the 49ers are still negotiating Williams’ deal, that uncertainty can change how aggressive they are at left guard. It’s one thing to pay for a veteran guard when you know your All-Pro LT is locked in; it’s another if you might be retooling the entire left edge.
And then there’s the football risk: stacking a 34-year-old guard next to a 37-year-old tackle raises the stakes on durability and late-career decline. Bitonio has been remarkably steady, but ESPN’s own free-agent blurb adds a key qualifier — “if Bitonio opts to return” — which is a reminder retirement is at least part of the conversation with older veterans.
If SF Wants Younger: Another ESPN Name to Watch
ESPN also floated Alijah Vera-Tucker as an alternative if the 49ers want to go younger at left guard. That’s the fork in the road: short-term certainty (Bitonio) vs. age curve (a younger starter) — and that decision likely depends on whether Williams’ contract gets smoothed out quickly or drags.
Local 49ers coverage has already highlighted how thin the left-guard outlook looksright now, which is why the “just draft it” plan may not feel safe for a team trying to contend immediately.
What happens next?
The 49ers Joel Bitonio signing chatter is only going to get louder as Williams’ contract talks stay in the spotlight and the 49ers finalize their offseason priorities. The big tell will be timing: if Williams’ situation resolves early, a veteran guard swing makes more sense; if it lingers, San Francisco may hedge with a younger, longer-term option.
