Warner entered 2025 having posted between 130 and 137 tackles in four consecutive seasons before his ankle injury limited him to just 51 tackles across six games. He faced no restrictions in the 2026 offseason program and is expected to return immediately to his full workload, a promising sign for a player who has missed only one game in seven professional seasons. Bosa, meanwhile, participated fully in 49ers practice for the first time this week after fighting through patellar tendinitis, and he described the session as "very encouraging" ahead of the Week 1 opener.

Bosa's absence was catastrophic for San Francisco's pass rush, as the team finished dead last in the NFL with 20 total sacks in 2025. When healthy in 2023, Bosa posted 10.5 sacks across a full season, and his career floor when active sits at nine-plus sacks per year. If both Warner and Bosa return to their established production levels, San Francisco's defense should climb back into the top tier of the league after bottoming out without them.

Brock Purdy has yet to complete a 17-game regular season, but 2026 is the year he finally changes that narrative and delivers the most complete campaign of his career. Turf toe and shoulder injuries limited Purdy to nine starts in 2025, yet he still completed 69.4% of his throws for 2,167 yards, 20 touchdowns and a 100.5 passer rating while San Francisco went 7-2 in his starts. That production over a full slate, with greater continuity around him, points to a quarterback capable of eclipsing his prior bests.

Purdy's career highs came in 2023, when he threw for 4,280 yards and 31 touchdowns while leading the NFL at 9.6 yards per attempt. He does not need to replicate that eye-popping efficiency to surpass those totals, especially if he remains available for all 17 games and benefits from a healthier supporting cast. His 77.8% on-target rate led the NFL last season, underscoring that his accuracy remains a genuine strength rather than a product of Kyle Shanahan's system.

Expect Purdy to set new personal highs with more than 4,300 passing yards and 32 touchdown passes. A healthier season should also allow him to rediscover the off-schedule mobility and timing that made San Francisco's offense dangerous in 2023. If he stays upright, Purdy can move from efficient starter to legitimate MVP candidate.

San Francisco's 2025 season ended in humiliating fashion, a 41-6 divisional-round beatdown at the hands of the eventual Super Bowl champion Seahawks, who also swept the 49ers in the NFC West at 14-3. That loss came with Purdy managing a nagging shoulder stinger and Warner and Bosa both watching from injured reserve, a far cry from a healthy roster. With both defensive stars back and Purdy entering a contract year with full health, Shanahan's roster has the pieces to erase that memory.

San Francisco already proved it can win in the postseason, defeating Philadelphia 23-19 in the wild-card round behind two Purdy touchdown passes. Restoring the defense to its earlier form while getting a full season from Purdy should be enough to push past the divisional round this time, and an NFC Championship berth is well within reach if health cooperates.

These three predictions all trace back to the same root cause behind San Francisco's late-season collapse: injuries to its two most important defenders and its starting quarterback. If Warner, Bosa and Purdy all stay on the field for a full slate in 2026, the 49ers have shown enough during healthy stretches to be considered legitimate NFC contenders once again.
