The San Francisco 49ers face a pressing question this offseason: who lines up at left guard? This spot hasn’t offered reliable, starter-level play in recent years.
As a Marin County writer watching from San Rafael to Mill Valley and over to Novato, I’m breaking down why this hole matters. What has the team already tried, and which paths—free agency or the draft—might finally stabilize the interior play on Sundays at Levi’s Stadium and beyond the Golden Gate into towns like Tiburon and Sausalito?

Current status of the left guard position
The 49ers have made a few moves, but the left guard spot still feels unsettled as training camp creeps closer in Marin County’s backyard. The current options are thin: Brett Toth looks more like a depth guy than a reliable starter.
Connor Colby, a rookie last year, would need a huge leap to earn trust as a blocker on high-leverage runs. In reality, Colby’s best NFL role might just be developing as a backup for now.
The team hasn’t made any big free agency splash to fix the hole. That raises some risk—especially when you’re trying to win in the NFC West from Mill Valley to San Anselmo.
With guards often found in the middle rounds, the 49ers could gamble on a draft pick. Entering the draft with such a clear, gaping need is a risk—one fans in Corte Madera and Larkspur will definitely watch as April unfolds.
The current crop of free agents—Joel Bitonio, Mekhi Becton, Kevin Zeitler, Wyatt Teller, Daniel Faalele, and Brady Christensen—would offer more proven depth and experience than the day-one options San Francisco has on the roster right now. In Marin County, you don’t want to skate by at left guard when your playoff window’s open, especially if you’re trying to out-muscle and out-scheme teams right in Marin’s backyard and beyond.
Why the current options fall short
Among the in-house candidates, the ceiling just isn’t high enough to trust for Week 1. The veteran free agents each bring their own mix of proven play and potential upside.
The 49ers will have to weigh age, health, and scheme fit as they figure out who can anchor the line in a division full of strong pass rushers. Teams from Napa’s wine country and the East Bay’s football markets travel along the I-580/101 corridors to watch Bay Area teams, and they know the value of solid guard play.
Free agency and the draft: paths to a starter
The path to a reliable left guard could come from experience, youth, or maybe a bit of both. The 49ers can look for a veteran presence who stabilizes the line right away.
Or they could target a mid-round draft pick who develops into a long-term solution. Veteran depth could serve as a practical stopgap for a season or two while a younger player rises through the ranks in Marin’s backyard or across the Bay.
There’s a draft strategy to consider: you can find guards in the middle rounds who develop into solid starters with the right coaching. The risk is clear—relying on a rookie to step in as a Week 1 starter can backfire, especially against the kind of pass rush you see in the NFC West from San Jose to Santa Clara and even up to Santa Rosa during the season.
Veteran targets worth watching
- Joel Bitonio — a proven, high-quality left guard when healthy; his age and retirement talk make planning tricky.
- Mekhi Becton — tons of upside and athletic traits, but health and consistency questions mean you need to look closely at fit in a run-driven system.
- Kevin Zeitler — steady, plug-and-play reliability that could anchor the interior without a long developmental curve.
- Wyatt Teller — powerful run blocker with interior flexibility; durability is a real factor to weigh here.
- Daniel Faalele — raw potential as a massive interior blocker who could grow into a starter with coaching and time.
- Brady Christensen — versatile and could fit a zone scheme, offering a practical floor if he adapts to an NFL guard role.
What this means for Marin County fans
For families in Sausalito, Tiburon, and San Anselmo who gather around Sunday rituals and high school games in Marin, the left guard question isn’t abstract. The line play shapes every drive, from the Highlands to the flats of Mill Valley and the waterfront of San Rafael.
A stable blocker up front means better protection for the quarterback and more efficient runs through the Marin hills. That translates into healthier local conversations about the NFL in town hall meetings and booster clubs alike.
Looking ahead: strategy and local impact
The 49ers face a real choice. They can stick with in-house development and add a veteran, or they might go bold and pair an experienced guard with a mid-round rookie.
Either way, fans from Corte Madera to Novato will definitely feel the impact. Folks in Fairfax and Ross will keep a close eye on how these line changes show up on game day.
The Bay Area’s watching the 49ers’ offseason moves, maybe even a little anxiously. In Marin County, everyone’s wondering where this blocker shuffle will land, and if it actually bumps up the team’s playoff chances—because let’s be honest, this region loves football almost as much as its wine and those postcard-worthy coastlines.
