Every year begins with a promise in Santa Clara — and a pressure that few franchises can match.
The San Francisco 49ers don’t just chase success; they chase legacy. Every snap echoes through decades of perfectionism — Montana’s precision, Rice’s brilliance, Young’s poetry, Kittle’s roar, Warner’s leadership.

The 2025 season carries that familiar hum: unfinished business. A roster so complete it borders on orchestral, yet bruised by playoff heartbreaks too vivid to forget. General manager John Lynch and head coach Kyle Shanahan know they’ve built something special — but in the NFL, “special” only matters if it ends with a trophy.

Before the first snap, before the first chant at Levi’s Stadium, the microscope returns. Position by position, strength by flaw, let’s grade the 49ers as they enter another defining campaign.

Quarterbacks — Grade: B+

If pressure is currency, Brock Purdy is now rich beyond measure.
Once the improbable last pick, now the unquestioned leader of a Super Bowl-caliber team, Purdy enters 2025 carrying both praise and scrutiny. His 2024 season reinforced what the league now accepts — he’s not a system quarterback; he is the system’s symphony.

Purdy’s anticipation, touch, and processing speed remain elite for his age. He finished last season top-5 in completion percentage and passer rating, thriving within Shanahan’s timing-based offense. Still, the criticism lingers — can he create chaos plays when the structure breaks?

Behind him, the 49ers quietly upgraded depth with Joshua Dobbs, a cerebral journeyman who understands motion-heavy playbooks, and rookie Tanner Mordecai, a developmental passer with arm talent but steep learning curve.

Verdict: They can win because of Purdy, not just with him — but only if he evolves beyond comfort zones.

Overall: B+ — steady, confident, but still chasing that defining “takeover” moment.

Running Backs — Grade: A

This group is the heartbeat.
Christian McCaffrey remains the purest hybrid weapon in football — a one-man storm who reads defenses like sheet music. At 29, his efficiency metrics defy gravity: vision sharper than ever, route running closer to an elite slot receiver than a tailback.

Behind him, Elijah Mitchell and Jordan Mason provide bruising insurance, though health and consistency remain question marks. Shanahan’s zone-scheme wizardry makes even third-string backs look explosive, but no one replicates McCaffrey’s versatility.

Add fullback Kyle Juszczyk, whose intelligence and blocking angles turn ordinary plays into clinic film, and you have the NFL’s gold standard backfield.

Overall: A — unmatched depth, IQ, and balance between finesse and ferocity.

Wide Receivers — Grade: A-

In a league obsessed with star duos, the 49ers boast an identity.
Deebo Samuel and Brandon Aiyuk aren’t just receivers — they’re tone-setters. Samuel remains the league’s most violent open-field runner, transforming short passes into collisions that feel like statements. His chemistry with Purdy is rhythm and rage blended.

Aiyuk, meanwhile, has ascended to true WR1 efficiency: crisp routes, silent swagger, surgical yards-after-catch timing. His 2024 breakout season forced defenses to pick their poison — bracket Aiyuk, and Deebo punishes you; focus on Deebo, and Aiyuk finds daylight.

Rookie Ricky Pearsall adds burst and hands made for third downs, while Jauan Jennings returns as the emotional anchor, a chain-mover with unteachable grit.

If there’s one question, it’s durability — both Deebo and Aiyuk have battled lingering soft-tissue strains. But when healthy, no group complements motion offense better.

Overall: A- — explosive, physical, selfless. The prototype for modern balance.

Tight Ends — Grade: A

George Kittle has entered his elder statesman era, but don’t mistake maturity for decline.
Still an All-Pro blocker and top-three receiving threat, Kittle’s leadership carries the tone of the entire offense — joyful violence. His chemistry with Purdy borders on telepathic; his body control remains ridiculous for his size.

Behind him, Cameron Latu and Brayden Willis provide youthful rotational value, with Latu flashing improved route polish in camp. Shanahan’s offense thrives on 12-personnel unpredictability, and the depth here finally matches his vision.

Kittle’s health will always be monitored — he plays like every snap is a dare — but when available, he changes geometry.

Overall: A — veteran excellence surrounded by emerging talent, still the emotional engine.

Offensive Line — Grade: B-

If there’s one shadow over this team’s brilliance, it’s protection.
Trent Williams continues to operate as football’s equivalent of a black hole — nothing escapes him. Even at 36, he dominates edge rushers with absurd leverage and footwork. But the question is sustainability.

Right tackle remains volatile: Colton McKivitz has heart but lacks elite lateral quickness, and the 49ers still flirted with upgrades in free agency. The interior — Aaron Banks, Jake Brendel, and Spencer Burford — is solid but inconsistent. Pressure through the A-gaps plagued Purdy late last season, particularly against aggressive blitz looks.

Depth additions like Ben Bartch and rookie Dominick Puni help, but this line’s performance may define the season’s ceiling.

Overall: B- — anchored by greatness, weakened by uncertainty.

Defensive Line — Grade: A-

If offense is art, the 49ers’ defensive front is warfare.
At the center of it all: Nick Bosa, a relentless technician who bends reality as much as he bends edges. His power, timing, and first-step precision remain unmatched.

The offseason brought reinforcements — Leonard Floyd, the veteran pass rusher who gives Bosa breathing space, and Maliek Collins, an interior disruptor replacing the departed Arik Armstead. Javon Hargrave remains the anchor inside, his bull rush still collapsing pockets like falling walls.

The rotation runs deep: Drake Jackson finally matured into a situational weapon, and Kalia Davis shows signs of becoming the next unsung breakout.

Still, Armstead’s leadership will be missed, and the run defense occasionally leaks in wide zones. But the pass rush remains elite enough to tilt games.

Overall: A- — violent, deep, capable of dictating game tempo.

Linebackers — Grade: A+

There’s no debate here. This is football’s model unit.

Fred Warner and Dre Greenlaw operate on instinctual wavelengths few duos ever achieve. Warner’s coverage range continues to redefine what a middle linebacker can be — he doesn’t just drop back; he erases. His pre-snap communication is essentially a second defensive coordinator.

Greenlaw, fiery and feral, brings thunder to Warner’s lightning. His sideline-to-sideline bursts and tackling angles set the tone for physical dominance. When he missed time last year, the defense’s emotional temperature dropped.

Depth behind them — Oren Burks, Marcelino McCrary-Ball — provides capable rotation but little star power. Still, with Warner healthy, the group’s synergy is unmatched.
