Fred Warner is convinced the San Francisco 49ers’ defensive backfield is better than its reputation suggests.
San Francisco enters 2026 without a single cornerback in Pro Football Focus’ top 32 at the position, and the numbers behind that snub aren’t pretty. Deommodore Lenoir, the presumptive No. 1 corner, took a step back last season, finishing with a 60.7 overall grade that ranked 65th among 114 qualified corners and allowing a 104.0 passer rating when targeted. Opposite him, Renardo Green graded 93rd overall and now faces real competition from offseason addition Jack Jones. As a group, Lenoir, Green and slot corner Upton Stout graded as PFF’s 28th-ranked cornerback unit in football last season, with the 25th-ranked team coverage grade, as San Francisco finished 25th in passing yards allowed.
None of that seems to have dented Warner’s confidence. Speaking with reporters, the star linebacker said he can’t recall feeling this good about a defensive back unit as he has in his entire career.
“That’s not even a knock on any teams that I played on before, but I think just the way that that group is kind of meshing together, the way that they’re playing sticky in coverage, playing the ball in the air, being able to, you know, play in the run game or ball thrown to the flat, the ability to tackle — I think it’s one of the best I’ve seen thus far,” Warner said. “I’m really excited about what I’m seeing, and we just got to continue to gel and mesh that thing together to where it’s the best version, like I said, for when the time comes.”
Warner’s optimism may partly trace back to Stout, who continues to garner praise this offseason. The 2025 third-round pick earned NFL.com All-Breakout Team recognition after playing 593 defensive snaps as a rookie, racking up 82 tackles, four tackles for loss, five passes defensed, two quarterback hits, a forced fumble and a sack. If Lenoir can rebound and Jones pushes Green for the outside job, Warner’s read on the room could prove prescient.
Still, the gap between Warner’s locker-room assessment and PFF’s outside evaluation is significant, and it puts real weight behind his closing caveat: the group still has to gel and reach its best version by the time the games matter.
With training camp underway and a Week 1 opener against the Rams in Australia on the horizon, San Francisco’s defense — and its Super Bowl hopes — may hinge on which read of the secondary turns out to be right.
