Top 25 Defensive Free Agents for the 2025 NFL Season

The phrase “defense wins championships” was powerfully illustrated in the 2024 NFL season, as the Philadelphia Eagles dominated the Kansas City Chiefs in Super Bowl LIX, thanks largely to their formidable defense. This defensive prowess highlighted the importance of a strong defensive lineup. As the new NFL league year approaches on March 12, many top defenders will hit the free agent market. Here’s a preview of the 25 best defenders available for teams to sign.

Honorable Mentions

Before diving into the top 25, it’s worth noting some additional players who nearly made the cut:

• Raiders LB Robert Spillane
• Colts DE Dayo Odeyingbo
• Eagles DE Haason Reddick
• Buccaneers LB Lavonte David
• Cardinals DE Baron Browning
• Raiders LB Malcolm Koonce
• Raiders DE Chauncey Golston
• Jets LB Jamien Sherwood
• Vikings CB Stephon Gilmore
• Chiefs DT Tershawn Wharton
• Seahawks LB Ernest Jones
• Commanders LB Bobby Wagner

Azeez Ojulari

Azeez Ojulari brings 22 career sacks in 46 games, an impressive numbersheet. However, his quarterback pressures and pressure rate are less than stellar. With only 108 career pressures (ranked 66th among sack leaders since 2021) and a pressure rate of 10.8% (51st ranked), Ojulari’s potential as more than a pass rusher is questionable. At 25, he has time to develop, but his viability as a full-fledged contributor remains to be seen.

Justin Simmons

Justin Simmons has compiled an impressive 34 interceptions since 2016, with two more in 2024. His transition to the Falcons in his first season was a success, showcasing his impact on the defensive backfield. At 31, his experience and tackle skills can be valuable assets to any contender looking to strengthen their defensive presence.

Levi Onwuzurike

Levi Onwuzurike’s build and skill set make him a versatile option at the defensive line. Standing at 6-foot-3 and 290 pounds, he has the physicality and potential to be a future star. However, his injury history, with 25 games missed over four seasons, is a significant concern. If he can improve his durability, Onwuzurike could become a valuable signing.

Dre Greenlaw

Dre Greenlaw has been the San Francisco 49ers’ defensive X-factor, significantly improving their performance when on the field. Despite his Achilles tear limiting him to just 34 snaps in 2024, Greenlaw is only 28 and may bounce back. His potential to rejuvenate the 49ers’ defense is noteworthy.

DeMarcus Lawrence

DeMarcus Lawrence’s resilience is evident, as he continued to disrupt with three sacks, a forced fumble, and four tackles for loss before suffering a season-ending foot injury. At 33, he could be a reliable complement to another top edge rusher, adding depth and vetted experience to an already formidable defensive line.

Asante Samuel Jr.

Asante Samuel Jr. played just four games in 2024 due to a shoulder injury but showed his skills as a solid cover corner before going on IR. At 26, he still has time to recover and continue his career. While his tackling might improve with age, Samuel’s potential as a valuable corner remains strong.

Paulson Adebo

Paulson Adebo started 2024 with a strong showing, but a season-ending broken femur injury cut it short. Despite playing just seven games, Adebo’s defensive prowess was evident with his 44.1 passer rating against. If healthy, he could become a standout cover corner, making him a promising free agent.

Rasul Douglas

Rasul Douglas is known for his ball-hawking ability, with 14 interceptions since 2021. At 30, his career total of 45 passes defended speaks to his consistent defensive impact. While his age may be a factor, Douglas could provide a solid complement to any secondary.

Jourdan Lewis

Jourdan Lewis proved his versatility while playing nickel and starting outside corner in Dallas. His football IQ and tackling make him a valuable player against both the pass and run. At 30, Lewis remains a valuable option for enhancing any defensive unit.

Trevor Lawrence and Justin Bynum

Trevor Lawrence’s heavy blitz scheme in Minnesota played to Justin Bynum’s strengths, with Bynum recording a career-high three interceptions and showcasing his tackling skills. As a versatile safety, Bynum’s impact could be significant in various defensive formations.

Tre’von Moehrig

Moehrig has been a consistent performer, with career-high 104 tackles, five interceptions, five tackles for loss, and 15 passes defended in 2024. His durability and versatility make him a valuable asset, and at 25, he could potentially elevate his game with a strong supporting cast.

Chase Young

Chase Young’s 2020 NFL Defensive Rookie of the Year award was the start of a promising career, and with 21 quarterback hits in 2024, his pass pressure skills remain a threat. Young’s potential to turn his recent performance into consistent play over time is noteworthy.

Hunter Morgan Mack

Hunter Morgan Mack’s production dipped significantly in 2024, with only 6 sacks and 49 quarterback pressures compared to 17 sacks and 88 pressures in 2023. Despite his age (34), his experience and potential to revert to form make him an intriguing target for contenders.

Nick Bolton

Nick Bolton has been the Kansas City Chiefs’ leading tackler over the past few seasons, including 106 in 2024. At 24, his ability and work ethic make him a viable option for teams looking to bolster their linebacker corp.

JaCoby Hufanga

JaCoby Hufanga showed promising signs as a starting defensive end in 2022, but injuries have hampered his development. If he can stay healthy, Hufanga’s talent and potential make him a valuable acquisition.

Charvarius Ward

Charvarius Ward faced off-field issues in 2024 but remains a talented contributor to the defensive line. With a second-team All-Pro selection in 2023, he can likely secure a significant contract before his 29th birthday in May.

Carlton Davis

Carlton Davis had a strong season in Detroit, with a 62.7 passer rating against as the primary defender. Despite ending the year with a broken jaw, his performance has earned him a sizeable raise, and his continued improvement is expected.

Justin Reid

Justin Reid’s solid defensive play in 2024 and elevated production despite a rookie-like presence on the injury-blighted Eagles make him a valuable asset. His potential to continue growing, especially with the addition of Jaden Hicks, ensures he will command a competitive salary.

Osa Odighizuwa

Osa Odighizuwa’s impressive 60 quarterback pressures, second only to Zach Allen’s 75, put him on the radar for teams seeking depth or a potential star. At 26, he is positioned well for a sizable, long-term deal.

D.J. Reed

D.J. Reed’s significant improvement in both pass rush and coverage in 2024 makes him one of the top cornerback options available. With a futuristic skill set and the ability to thrive on any team, Reed could be a game-changer for any contender.

Jevon Holland

Jevon Holland’s 90.4 PFF defensive grade in 2023 was third among safeties, a testament to his consistent play. Despite a shortened season in 2024 due to injury, Holland’s potential at age 25 keeps him in high demand.

Byron Murphy Jr.

Byron Murphy Jr.’s breakout year in 2024 saw him named a Pro Bowler with career-high interceptions, passes defensed, and tackles – all in the Vikings’ heavy-blitz defensive scheme. At 27, he is poised for a lucrative payday and could be a defensive leader on any team.

Milton Williams

Milton Williams’ strong 2024 season saw him set career-highs in sacks and quarterback pressures, ranking fourth in pass rush win rate. At 25, his future potential is high, making him a valuable free agent for any team looking to improve their defensive depth.

Zack Baun

Zack Baun’s transition to inside linebacker with the Philadelphia Eagles proved successful, leading to a robust contract offer in 2025. His 151 tackles and five forced fumbles made him a key player in Philadelphia’s championship run, solidifying his status as a top free agent.

Josh Sweat

Josh Sweat’s eight sacks in 2024, building on his 11 sacks in 2022, make him a standout edge rusher. His performance in Super Bowl LIX, with 2.5 sacks and seven quarterback pressures, cements his status as one of the elite defenders in free agency. His value will likely make him one of the highest-paid free agents.
