NFL free agency is almost set to begin, and we're keeping track of every major signing, trade and release of the 2025 offseason, with analysis from our NFL Nation reporters and grades from our experts. The new league year begins March 12 at 4 p.m. ET, and free agent signings can then become official. The first round of the 2025 NFL draft begins April 24 on ESPN.
The Chargers' first big move came in the form of a new one-year deal for former NFL Defensive Player of the Year Khalil Mack.
Here's a breakdown of every 2025 NFL free agent signing by the Los Angeles Chargers and how each will impact the upcoming season:
Khalil Mack, LB
Mack and the Chargers reached an agreement on a one-year, fully guaranteed $18 million deal.
What it means: Mack had been the Chargers' top priority this offseason and helped them keep one of the league's best pass rushers for another year. Mack has a team-high 23 sacks over the last two seasons, and he led all Chargers players with a 13% pass rush win rate en route to his ninth Pro Bowl last season. The deal allows the Chargers to focus on the rest of the roster, where the team's needs are aplenty, including interior offensive line, defensive line, and wide receiver. The Chargers have already lost defensive tackle Poona Ford (Rams) and wide receiver Joshua Palmer (Bills).
What's the risk: There isn't much risk on this deal. It is a one-year, fully guaranteed $18 million contract, which is close to average for the booming edge rusher market. Mack, 34, didn't show much sign of decline in 2024 and is one of the team's most respected players.
