Injuries have hollowed out San Francisco's defensive interior, forcing a gamble on Naquan Jones. Unless the run defense stabilizes, a blockbuster trade may be the only championship-saving move.
The San Francisco 49ers are sitting pretty at 2-0 following back-to-back double-digit victories, but beneath the surface of their high powered start lies an alarming issue right in the heart of their defense.
San Francisco’s interior defensive line depth has been completely decimated by injuries:
- Alfred Collins is out for the year after suffering a torn patellar tendon.
- Rookie James Thompson Jr. is sidelined for roughly six weeks with a high ankle sprain.
- Second-year nose tackle CJ West was placed on Injured Reserve after undergoing knee surgery to remove bone chips.
Desperate for run stoppers, general manager John Lynch signed 28 year old veteran nose tackle Naquan Jones off the Minnesota Vikings’ practice squad to a one year deal. While Jones provides immediate mass at 6-foot-3 and 313 pounds, the harsh reality is that San Francisco needs him to play significant snaps right away and not just as a depth guy.
The Hidden Flaw in San Francisco's 2-0 Start
While Kyle Shanahan’s offense has blown games open early, the 49ers' interior run defense has struggled immensely when games are actually close.
Through the first two weeks, San Francisco's defense has surrendered 5.0 yards per carry when the score margin sits between 0 and 9 points. Up to this point, their most effective run defense has simply been their offense building massive multi-score leads and forcing opponents to abandon the run.
Eventually, the 49ers will run into a physical, contending team that keeps the score tight late into the fourth quarter. If San Francisco cannot plug the interior gaps on early downs, their run defense could end up being their Achilles' heel when January comes around.
Why Naquan Jones Might Just Be Step One
Signing Jones gives the front office a few weeks to evaluate if he can hold up as a primary nose tackle. But if the interior continues to bleed yards against the run, expect Lynch to be extremely aggressive on the trade market ahead of the deadline.
One obvious trade target to watch is Washington Commanders defensive tackle Daron Payne.
Washington is off to a rocky 0-2 start and recently saw starting quarterback Jayden Daniels go down with an injury. If the Commanders' season continues to derail, trading away veteran assets for future draft capital will become a top priority for their front office.
Payne, 29, fits the exact profile San Francisco needs:
- Monster Run Stopper: An elite, Pro Bowl-caliber interior anchor who destroys double teams.
- Impending Free Agent: Entering the final year of his deal with a $16+ million base salary, making him a prime candidate to be moved for mid-round draft capital (likely a 3rd or 4th-round pick).
- Cap Compatibility: San Francisco possesses the cap flexibility required to absorb his remaining salary without jeopardizing their long-term structure.
All-In on 2026
Placing Payne in the interior next to Mykel Williams and flanked by Nick Bosa on the edge would instantly transform San Francisco’s front four back into a terrifying unit.
The 49ers are in a championship window, and they owe it to themselves to patch this interior weakness before it costs them in the postseason. Signing Naquan Jones keeps the boat floating for now, but don't be surprised if John Lynch pulls off a major splash at the trade deadline to push this defense over the top.
