Look, if you’re asking about the guy under center in Santa Clara, the answer hasn't changed, but the conversation around him definitely has. Brock Purdy is the quarterback for the San Francisco 49ers.
But it’s never just that simple with the Niners, is it?
We’re sitting here in January 2026, and the "Mr. Irrelevant" tag feels like a lifetime ago. Honestly, it’s kinda wild to think people were calling him a "system QB" just a couple of seasons back. Now? He’s the engine of a team that finished the 2025 regular season with a 12-5 record. He’s not just a placeholder. He’s the guy the franchise is prepared to pay—and pay big.
The State of the 49ers Quarterback Room in 2026
Right now, the depth chart is pretty clear, but it has a different flavor than previous years.
Brock Purdy is the undisputed QB1. Behind him, the Niners have brought in some interesting insurance. You’ve got Mac Jones sitting there as the primary backup. It's a bit of a reclamation project for Kyle Shanahan, taking a former first-round pick who struggled elsewhere and putting him in a system that prizes timing and accuracy. They also have Kurtis Rourke in the mix, filling out the room.
But make no mistake: this is Purdy's team.
During the 2025 season, Purdy continued to put up numbers that make the "game manager" critics look a little silly. We're talking about a guy who threw for 20 touchdowns and 10 interceptions through the bulk of the season, maintaining a passer rating north of 100. He isn't just dinking and dunking to Christian McCaffrey. He’s pushing the ball downfield to Brandon Aiyuk and Ricky Pearsall, who has really stepped up in the rotation.
What Happened During the 2025 Season?
The 49ers' journey to this point hasn't been a total cakewalk. They’ve dealt with the usual Bay Area drama—injuries, contract holdouts, and the relentless pressure of a championship-or-bust window.

In late 2025, the team went on a tear. Between November and December, Purdy was lights out. He had a 140.3 passer rating against Tennessee in mid-December and followed it up with a 5-touchdown masterpiece against Indianapolis.
- December 14 vs. TEN: 295 yards, 3 TDs, 0 INT.
- December 22 @ IND: 295 yards, 5 TDs, 1 INT.
- January 11 @ PHI: A gritty 23-19 win to keep momentum alive.
Then came the weird stuff. A regular-season finale loss to Seattle where the offense just... stalled. Purdy went 15 for 27 for only 140 yards. It’s those types of games that keep the talk radio lines buzzing in San Francisco. People start wondering if the "real" Purdy is the one who carves up Indy or the one who struggled against the Seahawks' pass rush.
The Contract Elephant in the Room
You can't talk about who is the quarterback for San Francisco without talking about money.
Purdy has been playing on one of the most team-friendly deals in professional sports history. Because he was the last pick in the 2022 draft, his cap hit has been negligible. That's how the 49ers were able to afford a "Super Team" roster.
But 2026 is a massive year for negotiations. The 49ers are staring down the barrel of a contract extension that could easily cross the $50 million-per-year threshold.
Why does this matter to you? Because the way Purdy plays in these 2026 playoffs determines his leverage. If he leads them to another deep run, the Niners basically have to hand him a blank check. If they exit early, the "can he win the big one?" narrative gets a second life, even if it’s unfair.

It's sort of exhausting, right?

Every time Purdy hits Deebo Samuel for a 40-yard gain, someone on the internet says, "Any QB could do that in Shanahan's offense."
Nuance matters.
Yes, Kyle Shanahan is a genius. Yes, having Christian McCaffrey in the backfield is like having a cheat code. But if you watch the tape from the 2025 season, you see Purdy making "off-schedule" plays. He’s escaping the pocket, keeping his eyes downfield, and throwing into windows that didn't actually exist when the play started.
He leads the league in several advanced metrics like Air Yards per Attempt and Passer Rating under pressure. You don't get those stats by just being a robot who follows a script.
Who Else Is in the Mix?
While Purdy is the man, the 49ers' front office is always looking ahead. Mac Jones is the high-floor backup. If Purdy were to go down, the season wouldn't necessarily be over, which is a lesson the Niners learned the hard way in the 2022 NFC Championship game.
There’s also the draft. John Lynch and Shanahan have shown they aren't afraid to take big swings, though they’ve been much more conservative since the Trey Lance era ended. For now, the focus is entirely on supporting #13.
What Most People Get Wrong About the 49ers QB Situation
People think the 49ers are looking for an upgrade. They aren't.

The locker room is obsessed with Purdy. Trent Williams, the veteran left tackle, has gone on record multiple times saying Purdy is the "alpha" of that huddle. That kind of veteran respect isn't given; it's earned.
The misconception is that the 49ers are successful despite Purdy. The reality is they are successful because of his efficiency. He doesn't turn the ball over at the same rate as the guys they had before him (Jimmy Garoppolo, for example).
Actionable Insights for Fans and Analysts
If you're following the Niners through this 2026 postseason, here is what you need to watch for to see if Purdy is "on":
- The 10-Yard Out: If Purdy is hitting the sideline routes with zip in the first quarter, the defense is in trouble.
- Third-Down Scrambles: Watch his legs. In 2025, he became much more willing to tuck the ball and run for 6 yards when the coverage was tight.
- The Red Zone: The 49ers' efficiency in the red zone plummeted during their losses in late 2025. If they are settling for field goals, it usually means the timing between Purdy and his tight ends is slightly off.
The 49ers are in a "win now" window that is starting to feel like it might be closing soon due to the salary cap. That puts an immense amount of pressure on the quarterback.
Check the injury reports weekly. While Purdy has been durable, the 49ers' offensive line has seen some age-related regression. His ability to stay clean in the pocket is the single most important factor for San Francisco's success this month.
If you’re betting on or tracking the team, keep an eye on the practice reports for Mac Jones too. If he’s getting more first-team reps than usual, it might signal a lingering "stinger" or minor injury for Purdy that the team isn't broadcasting.
Stay locked into the local beat writers like David Lombardi or Matt Maiocco. They usually catch the small details in warmups that tell you if Purdy is favoring his arm or moving a bit gingerly. In a high-stakes environment like the NFC West, those small details are everything.
