The San Francisco 49ers are headed into a playoff week with a very familiar kind of stress: the coaching-carousel kind.
49ers insider David Lombardi summed up the gut-punch scenario with one post: “49ers’ nightmare: Robert Saleh to Baltimore and John Harbaugh to Arizona.”
On its face, it’s just one spicy tweet. But the timing is what makes it feel real. Baltimore just fired longtime head coach John Harbaugh on January 6, 2026, creating a premium vacancy. And the Arizona Cardinals already opened their own head-coaching search by moving on from Jonathan Gannon on January 5.
Meanwhile, the 49ers’ defensive coordinator is suddenly back on the interview circuit.
Key details (why this matters today)
- Cardinals requested an interview with 49ers defensive coordinator Robert Saleh for their head coach opening, per Albert Breer.
- 49ers are prepping for a Wild Card game vs. the Eagles this Sunday in Philadelphia.
- Ravens fired John Harbaugh on January 6, officially putting a top job on the market.
- Cardinals fired Jonathan Gannon after a 3-14 season, accelerating the NFC West coaching search.
The Robert Saleh part of the “nightmare” isn’t hypothetical anymore
Saleh is already being tied to Arizona’s opening, with NBC Sports Bay Area reporting the Cardinals submitted an interview request to San Francisco.
Saleh is in his first season back as the 49ers’ defensive coordinator after his earlier run in the role (2017–2020) and a head-coaching stint with the New York Jets that ended mid-2024.
Arizona’s interest also makes simple football sense: the Cardinals’ defense was a mess in 2025, allowing 6,081 total yards and 488 points, according to NBC Sports Bay Area. A team bleeding yards and points typically wants a culture-reset hire, and Saleh’s calling card has always been energy + structure.
Now add in Baltimore entering the market. If the Ravens decide they want a defensive-minded head coach who has done the job before, Saleh will be on a lot of shortlists, especially with a fresh playoff spotlight coming this week.
The Harbaugh-to-Arizona twist would be a full NFC West headache
Here’s where Lombardi’s “nightmare” framing gets extra mean for 49ers fans: the second part isn’t just losing a coordinator. It’s the idea that John Harbaugh could land with a division rival.
Arizona has already confirmed it’s beginning a coaching search, with owner Michael Bidwill and GM Monti Ossenfort acknowledging the process won’t be rushed. Harbaugh is now officially available after Baltimore’s decision.
If that pairing ever happened, it would instantly raise the “annoying factor” for San Francisco. Harbaugh is a Super Bowl-winning head coach with nearly two decades of institutional Baltimore credibility. And the NFC West already lives on thin margins, one major hire can swing a division’s next two years. The NFC West sent three teams into the playoffs this season, and Rams head coach Sean McVay, Seahawks head coach Mike Macdonald and 49ers head coach Kyle Shanahan are all among the best coaches in the NFL.
What happens next (and the one silver lining)
This week is about permissions, rules, and timing as much as it’s about “who wants who.”
Arizona’s own site spelled out how NFL interview rules can shape the early days of the carousel, including restrictions and virtual requirements for some assistants depending on playoff status and timing. That matters because the 49ers are actively preparing for a postseason game, and any Saleh movement would have to navigate league process.
There is also one cold comfort for the 49ers if Saleh does get hired away: the NFL has awarded special third-round compensatory picks to teams that develop minority candidates who are hired as head coaches or GMs, something the league has previously applied to the 49ers’ coaching tree (including Saleh).
But nobody in San Francisco is hanging a banner for “we got picks.” Not in January. Not with a playoff game on deck. The real fear is exactly what Lombardi posted: losing a key defensive voice and watching a proven, battle-tested head coach show up in the neighborhood.
