NFL free agency is officially underway, 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 began March 12 at 4 p.m. ET, and free agent signings could then become official. The first round of the 2025 NFL draft begins April 24 on ESPN.
Here's a breakdown of every 2025 NFL free agent signing by the Las Vegas Raiders and how each will impact the upcoming season:
Darnay Holmes, CB
Las Vegas and Holmes agreed to a one-year deal.
What it means: Las Vegas added much-needed depth to its secondary, especially at nickel cornerback. In his first season with the Raiders, Holmes gave up 22 catches for 172 yards and a passer rating of 90 in 280 defensive snaps, including 220 as a slot cornerback.
What's the risk: There's no risk here. Holmes is a solid depth piece for the Raiders secondary. It still wouldn't hurt the Raiders to add more talent at the cornerback position.
Raheem Mostert, RB
Mostert agreed to a one-year, $2.1 million contract with Las Vegas.
What it means: The Raiders needed to revamp the running backs room after finishing last in rushing yards 79.8 per game. In 2023, Mostert made his first Pro Bowl appearance after rushing for 1,012 yards and a league-best 18 touchdowns. He had 2,181 rushing yards and 28 total touchdowns during his three-year tenure with the Dolphins. If Mostert can play closer to his efforts in 2023 and 2022, he will be a significant upgrade to the offense at a low cost.
What's the risk: Mostert turns 33 in April and is coming off a down year in 2024, largely due to De'Von Achane emerging as Miami's top running back. Mostert is a solid veteran addition, but the Raiders will need to take advantage of a deep running back class to strengthen the room and build for the future.
Eric Stokes, CB
The former Green Bay Packers player agreed to a one-year, $4 million contract.
What it means: Stokes, a 2021 first-round pick, will have a chance to compete for reps at outside cornerback with Jack Jones, Decamerion Richardson and Jakorian Bennett. Stokes has played 92.3% of his career defensive snaps on the outside. In 2024, he played in all 17 games for the first time in his career and gave up 31 catches for 343 yards, three touchdowns and a passer rating of 102.3.
What's the risk: Stokes has battled injuries, missing 23 career games. While he adds depth to the cornerback room, the Raiders still need to address the nickel spot since Nate Hobbs agreed to join the Packers.
Lonnie Johnson Jr., S
What it means: Johnson, who spent the first three seasons of his career in Houston, has played for three teams in three seasons. He will provide secondary depth and support on special teams. As a member of the Carolina Panthers in 2024, Johnson played 339 snaps on special teams compared to 13 on defense and just five in pass coverage.
What's the risk: None. Johnson will primarily be used as a core special teamer and a backup in the secondary.
Elandon Roberts, LB
Roberts is signing with the Raiders on a one-year, $3 million contract.
What it means: Roberts joins the Raiders after they lost starting inside linebacker Robert Spillane to the New England Patriots. Roberts, a two-time Super Bowl champion with New England, spent the last two seasons in Pittsburgh, where he collected 147 tackles in 33 games (29 starts). In 2024, he played in all 17 games, totaling 46 tackles and nine run stops. Roberts, who also spent three years in Miami, will have a strong chance to win the starting inside linebacker job given the current depth at the position.
What's the risk: There's no risk with this deal. Roberts provides veteran experience and fills a position of need.
Jeremy Chinn, S
Chinn comes to Las Vegas from Washington on a two-year deal for over $16 million.
What it means: After former Raiders safety Tre'von Moehrig signed a three-year deal with the Carolina Panthers, Las Vegas needed someone to fill a significant hole on defense. Chinn is coming off one of the best seasons of his career, totaling 117 tackles (seven for loss) and five passes defended. Chinn provides versatility in the secondary. He played 408 defensive snaps at safety, 193 in the slot, 287 at outside linebacker and 40 at inside linebacker.
What's the risk: This is another deal by the Raiders that doesn't have a ton of risk. It was going to be hard for the Raiders to retain Moehrig, and they were able to get a suitable replacement for less money.
Malcolm Koonce, DE
Koonce returns for one year and $12 million.
What it means: Even though Koonce missed the entire regular season with a torn ACL, he is 26 and has upside. In 2023, Koonce flashed his potential, totaling 43 tackles and a career-best eight sacks. He also had three forced fumbles and 17 quarterback hits. He would pair nicely with Maxx Crosby and has a chance to set himself up for a bigger deal next offseason.
What's the risk: There's no risk. The Raiders retained a quality pass rusher without breaking the bank. It's just a matter of Koonce returning to full strength.
Adam Butler, DT
Butler agreed to a three-year contract extension worth $16.5 million with $11 million in guarantees.
What it means: Las Vegas rewards Butler with a new deal after collecting 10 sacks over the past two seasons. In 2024, Butler had 65 tackles and five sacks while playing a career-best 858 defensive snaps. Coach Pete Carroll said during the NFL combine that he wants to retain key defensive players who are free agents. By keeping Butler, the Raiders have a solid defender up front and a veteran presence in the locker room.
What's the risk: None. It's a smart signing by the Raiders to retain Butler since the defensive line position is among their offseason needs.
Alex Cappa, G
Cappa is signing a two-year, $11.2 million deal with $5 million guaranteed.
What it means: The Raiders needed to address their offensive line. Las Vegas was 22nd in run block win rate and 17th in pass block win rate in 2024. The addition of Cappa provides experience up front. He has started in 96 of 102 career games between Cincinnati and Tampa Bay, where he spent the first four seasons of his career. Cappa was with the Tampa Bay Buccaneers when new Raiders GM John Spytek was there and has been durable during his career. He has played in 17 games each in three of the last four seasons.
What's the risk: Despite being durable, Cappa has a shaky track record. He has failed to record a pass block win rate above 92% in a season. Last year, he was ranked last in pass block win rate and 58th in run block win rate among 64 qualifying guards. Cappa could very well end up being nothing more than a depth piece for the team since the Raiders already have Jackson Powers-Johnson, Dylan Parham and Jordan Meredith.
