The San Francisco 49ers are on the search for a defensive coordinator once again after firing Nick Sorensen following just one season in that role.

The San Francisco 49ers could bring back a former defensive coordinator who knows the team well, with the goal of helping veterans like Nick Bosa and others in the 2025 season. The San Francisco 49ers definitely need a boost on defense.

But if you expected sweeping change, that will have to wait another year if anything like 6-11 happens again. The 49ers dismissed defensive coordinator Nick Sorensen and special teams coordinator Brian Schneider but will promote passing game specialist Klay Kubiak to offensive coordinator. With Shanahan still calling the plays.

When the ball dropped in 2024, the San Francisco 49ers were amongst the NFL's elite and primed for a deep postseason run. A month later, they blew a second-half lead to the Chiefs in the Super Bowl, watching as their opponents from Kansas City celebrated another championship. By the end of 2024, the Niners were the ones that dropped the ball.
