The San Francisco 49ers’ roster has undergone a significant transformation following a whirlwind of free agency moves and trades, setting the stage for a pivotal 2026 campaign. A comprehensive review of the updated depth charts reveals a team aggressively retooling on both sides of the ball, with major questions lingering at key positions.

Quarterback Brock Purdy, coming off a top-10 statistical season in 2025, remains the undisputed QB1, with his health paramount to the team’s fortunes. The backup situation, however, is in flux. While Mack Jones is currently penciled in as QB2 after winning five of eight starts last season, he remains a prime trade candidate, with the 49ers reportedly seeking high draft capital. Seventh-round pick Curtis Rour, praised for his pocket presence and toughness, is the projected third-stringer.

The offensive skill positions feature a dramatic overhaul at wide receiver. The headline acquisition is veteran Mike Evans, who immediately assumes the role of WR1. His physicality and deep-ball prowess are expected to open the offense for third-year pro Ricky Pearsall, who faces a critical “prove-it” season regarding his durability. Christian Kirk provides another veteran target, though the age of the top duo is a noted concern. The departure of Deebo Samuel elevates return specialist Junior Bergen into a more prominent role.

In the backfield, Christian McCaffrey returns after a 400-touch season, with the 49ers hopeful his meticulous conditioning can defy time. Second-year back Jordan Mason is poised for a larger role after showing promise late last season. The tight end position faces uncertainty, with star George Kittle unlikely to be ready for Week 1 as he recovers from a torn Achilles. This thrusts Jake Tonges into the lead role, with the draft a likely avenue to address the future.

The offensive line remains a focal point of concern, particularly at center and left guard. The signings of Brett Toth and Vedarian Lowe provide veteran depth and versatility but are not seen as definitive solutions. All-Pro tackle Trent Williams’s contract is expected to be restructured from its current massive cap hit, securing his vital presence for an otherwise average unit.

Defensively, the trade for disruptive interior lineman Osa Odighizuwa answers a glaring need for pass rush from the defensive tackle spot. His arrival reshapes a front that also features run-stuffers Alfred Collins and C.J. West. The health of edge rusher Nick Bosa, now recovering from his third ACL surgery, looms as the single biggest factor for the defense’s ceiling. His potential return to dominant form could catalyze the entire unit.

At linebacker, the reunion with Dre Greenlaw, provided he is healthy, restores one of the league’s premier duos alongside Fred Warner. Their collective playmaking and leadership are expected to stabilize the second level. The cornerback room sees new addition Nate Hobbs slotting in, likely in the nickel role, while the development of young players like Upton Stout and Renardo Green is crucial for depth.

Safety is arguably the roster’s weakest position. The tandem of Malik Mustapha and Ji’Ayir Brown is viewed as limited, with both better suited to play near the line of scrimmage. The 49ers are expected to continue exploring upgrades via trade or the draft to find a true center-fielder for the secondary.

Special teams see a change at punter, with Corliss Waitman replacing Thomas Morstead, while the reliable battery of kicker Eddy Piñeiro and long snapper Taybor Pepper returns intact. These moves conclude an aggressive period of roster churn for General Manager John Lynch and Head Coach Kyle Shanahan.

With the NFL Draft on the horizon, further adjustments are anticipated, particularly along the offensive interior and at safety. The 49ers have made bold strokes in free agency, banking on veteran stars like Evans and Odighizuwa to provide immediate impact while managing a delicate balance of age, injury recoveries, and financial constraints. The success of this strategy will define their quest to return to the summit of the NFL.

Following multiple signings and roster adjustments, the 49ers’ depth chart is starting to take a new shape. The changes provide insight into how the team may line up moving forward—and which areas could still see further upgrades.
