The 49ers’ Offseason Dilemma: Rebuilding the Defense for 2025

The San Francisco 49ers face a critical offseason as they look to recover from a disappointing 2024 campaign. The team’s defensive struggles, particularly on the interior line, have highlighted the need for major upgrades. With free agency and the draft on the horizon, the 49ers are in a race to solidify their roster and return to contention.

Addressing the Defensive Line: A Pressing Priority

The absence of Javon Hargrave in 2024 due to a torn biceps exposed a glaring weakness in the 49ers’ defensive line. Struggles in both the pass rush and run defense plagued the team throughout the season. With Hargrave now set to be designated as a post-June 1 cut, it’s evident that bolstering the defensive tackle position must be a top priority.

The Next Aaron Donald? Enter Walter Nolen

In Travis May’s latest three-round mock draft, the 49ers make a bold move by selecting Ole Miss defensive tackle Walter Nolen with the 11th overall pick. Nolen, who confidently described himself as “the next Aaron Donald,” brings impressive production to the table. His final season with the Rebels saw him amass 14 tackles for loss, 6.5 sacks, and 35 pressures—an output that justifies his high draft stock.

Nolen’s explosive ability to disrupt the pocket and his confidence in his skill set could make him a game-changer for the 49ers’ defense. Pairing him with Nick Bosa would provide the kind of dynamic pass-rushing duo San Francisco desperately needs.

Secondary Support: Benjamin Morrison at 43rd Overall

In the second round, May projects the 49ers to select Notre Dame cornerback Benjamin Morrison. Despite missing most of 2024 due to injury, Morrison has an impressive track record. His career passer rating allowed when targeted stands at a stellar 44.1, showcasing his lockdown capabilities.

With Charvarius Ward likely departing in free agency, Morrison’s addition would address a key need in the secondary. His potential to complement rising star Deommodore Lenoir and last year’s standout, Renardo Green, makes him a valuable asset for the 49ers.

Strengthening the Edge: J.T. Tuimoloau in Round Three

May rounds out the 49ers’ top three picks with Ohio State edge rusher J.T. Tuimoloau at 75th overall. Tuimoloau’s 2024 season has been nothing short of dominant, with 11.5 sacks and 20 tackles for loss. His ability to generate consistent pressure from the edge would alleviate the burden on Bosa and bring much-needed depth to the defensive front.

Tuimoloau’s physicality and knack for making game-changing plays could inject new life into a defense that struggled to maintain consistency last year.

Balancing Priorities: The Offensive Line Question

While upgrading the defense is critical, the 49ers must also address their offensive line issues. Injuries to Trent Williams and inconsistent performances from Colton McKivitz exposed vulnerabilities that contributed to the team’s offensive struggles in 2024. If the 49ers focus their early draft picks solely on defense, concerns about protecting their quarterback and establishing a strong run game will likely persist.

A Blueprint for a Comeback

If the 49ers execute this draft strategy, their defense will undoubtedly be better positioned to bounce back in 2025. Adding Walter Nolen, Benjamin Morrison, and J.T. Tuimoloau provides a combination of power, precision, and potential across the defensive unit.

However, the team’s success will hinge on finding balance. Addressing offensive line depth, either through later draft picks or free agency, is essential to ensure the team can compete on both sides of the ball. With careful planning, the 49ers have a chance to reestablish themselves as a powerhouse in the NFL.
