The interior of the defensive line would make sense to address quickly as San Francisco lost defensive tackles Javon Hargrave and Maliek Collins in free agency. Nick Bosa could use some help at defensive end rushing the passer as well. Leonard Floyd was among the 49ers' key free agency departures.

With a strong focus on the trade market and extending Brock Purdy, the San Francisco 49ers were not too active in the 2025 NFL free agency period. However, even with a modest effort, general manager John Lynch still made a few noteworthy acquisitions.

San Francisco checked in with the NFL's No. 30 free agency class, just ahead of Seattle at No. 31 and Atlanta at No. 32. Fellow NFC West squads Los Angeles and Arizona both cracked ESPN's top 13 free agency classes. The Rams ranked No. 2, while the Cardinals earned the No. 13 class.
