The upcoming free agency period presents significant challenges for the San Francisco 49ers as they prepare for the 2025 NFL season. With 24 players set to enter unrestricted free agency, the team must carefully manage its financial resources while ensuring key players remain part of the roster. The impending large contract for quarterback Brock Purdy adds an extra layer of complexity to their budgeting process. Despite this, the 49ers are expected to retain some of their less expensive free agents while letting others depart.

A standout player whose future with the team is under scrutiny is linebacker Dre Greenlaw. Even in his limited playing time after recovering from a serious Achilles injury sustained during the Super Bowl, Greenlaw demonstrated his importance to the defense. His return showcased the value he brings to the linebacking corps, which struggled significantly without him. Pro Football Focus highlighted Greenlaw as one of the indispensable free agents the 49ers cannot afford to lose. His presence would greatly bolster the run defense, which ranked poorly this past season. While there are risks associated with re-signing Greenlaw due to his recent injury history, his brief yet impactful performance suggests he could regain his form with proper recovery time.

The market for Greenlaw will be intriguing. Prior to his injuries, he was considered among the top off-ball linebackers in the league. Teams will likely approach signing him cautiously, but his potential and proven skills make him a valuable asset. Instead of searching for cost-effective replacements, the 49ers should prioritize retaining Greenlaw. His unique blend of athleticism, instincts, and tenacity is hard to come by, and keeping him on the team would provide stability and strength to the defense. This strategic move could ensure the 49ers maintain their competitive edge while exploring other areas where costs can be managed.
