The 49ers enter 2026 with a roster that looks sturdy almost everywhere you turn - except in one place that still jumps off the page.
According to Sharp Football Analysis, San Francisco lands inside the top 10 at four of five positional groups this offseason. The 49ers come in No. 6 at receivers and tight ends, No. 7 on the offensive line, No. 8 in the defensive front seven and No. 9 at quarterback. The only real drag on the overall picture is the secondary, which checks in at 26th and stands out as the clear weak link.
That back end doesn’t get a pass for familiarity, either. San Francisco brings back every starter from last season, when the defense managed just 6 interceptions all year, the fourth-worst total in the NFL.
The group is headlined by Deommodore Lenoir, Renardo Green and Upton Stout, and the 49ers also added veterans Nate Hobbs and Jack Jones. Even with those names in the mix, the secondary remains the roster’s biggest question mark. The challenge now falls to defensive coordinator Raheem Morris, who spent years coaching defensive backs.
Elsewhere, the picture looks much brighter. Up front, San Francisco’s defensive line is set up for a rebound after injuries limited Nick Bosa to three games in 2025. The arrival of Osa Odighizuwa adds another important piece, and the return of Dre Greenlaw gives the 49ers a strong pairing with Fred Warner in the middle of the defense.
Quarterback is another area that looks far healthier than it did a year ago. Brock Purdy’s 2026 outlook helped push the 49ers’ quarterback group into the top 10 for the first time. Purdy played only nine regular-season games last year, but he looked more like the player who finished fourth in MVP voting in 2023 than the one who struggled in 2024.
Just as important, Mac Jones gave San Francisco real stability behind him. In eight starts, Jones went 5-3 and posted a 62.3 total QBR.
The offensive line rounds out the strong spots. Trent Williams remains one of the league’s premier left tackles, and the unit allowed just 16 sacks last season, good enough to land seventh in Sharp’s rankings.
At receiver and tight end, the 49ers got deeper with the offseason additions of Mike Evans and Christian Kirk, joining Ricky Pearsall. George Kittle is also expected back from a torn Achilles early this season.
So while the roster grades read like those of a team with few holes, the secondary is the one area that still doesn’t match the rest of the operation. With four position groups inside the top 10 and one sitting well below average, San Francisco’s defensive backfield looks like the unit most likely to be tested early and often in 2026.

49ers Suddenly Linked To A Brandon Aiyuk Trade With QB Stakes
Brandon Aiyuks situation has only grown murkier for the 49ers, with the receiver not having played since October 2024 and his status around the roster increasingly difficult to ignore. Once viewed as part of the long-term offensive core, he now sits at the center of a conversation that has less to do with production and more to do with whether San Francisco can still count on the relationship at all.
Into that uncertainty comes the kind of speculative trade chatter that tends to follow a disgruntled star, and it comes with quarterback implications attached. Any move built around Aiyuk would force the 49ers to think beyond the receiver room and into their broader quarterback plan, especially with Mac Jones future in San Francisco already pointing toward a short stay and a possible eventual hunt for a starting job elsewhere.

49ers Safety Battle Already Has One Newcomer On Shaky Ground
The 49ers added Patrick McMorris in late April, giving the safety room another name to sort through as camp approaches, but his path looks narrow from the start. McMorris spent part of 2024 in Miami, where he appeared in six games before moving on to the practice squad circuit, and he arrives in San Francisco with the kind of profile that usually needs a strong summer to stand out.
Instead, the early read is that he has work to do just to stay in the conversation. Questions about his tackling, range and burst have made him a longshot for a regular-season spot, which leaves him fighting for a place in a crowded room that already has more established and higher-upside options. For now, the more realistic outcome appears to be another practice squad stint, unless he can change that evaluation before the 49ers have to trim the roster. [Read more 🡒]
One Under-the-Radar 49ers Addition Could Finally Settle Left Guard
The 49ers spent much of the offseason looking for reliable answers along an offensive line that has been in flux, and the left guard spot is still one of the cleaner training camp battles to watch. Chris Foerster has kept that competition open, with Robert Jones and Bret Toth among the names in the mix, while Toths value may stretch beyond one position since he is also expected to handle backup center duties no matter where he lines up.
For a team trying to make Brock Purdys life easier and keep the offense balanced around its established playmakers, that kind of stability matters as much as flashier additions on either side of the ball. Jones, in particular, has drawn attention as a low-profile pickup with the kind of experience and efficiency that can quietly settle a spot the 49ers have not fully locked down yet, even if the final call is still unresolved.
