Emmanuel Ogbah, Miami Dolphins

Ogbah has been a consistent defender for years. He had back-to-back nine-sack seasons in Miami in 2020 and 2021. The 30-year-old hasn't been a starter either of the past two seasons.

Carl Lawson, New York Jets

Lawson was a productive player for the Bengals and a big get for the Jets before the 2021 season, but he suffered a torn Achilles before his first year in New York. He returned with seven sacks in 2022, but only suited up for six games last season as a healthy scratch.

Romeo Okwara, Detroit Lions

More of a big-bodied defensive end than a pass rusher, Okwara has been a dependable piece of the Lions' defensive line rotation for the past six years.

Yannick Ngakoue, Chicago Bears

Ngakoue has been on six different teams the past five seasons, including a brief stint in Baltimore during the 2020 season. He logged a career-low 4 sacks with the Bears last year.

Charles Harris, Detroit Lions

Harris had a career-high 7.5 sacks in Detroit in 2021, but just 2.5 since after missing much of 2022 due to injury and then becoming more of a role player last year.

Randy Gregory, San Francisco 49ers

Gregory has bounced around a bit since his days in Dallas. He joined the 49ers late last season and posted 2.5 sacks in five games but was blanked in the playoffs.

Bud Dupree, Atlanta Falcons

The former Steeler had a bit of a resurgent season in Atlanta last year, registering 6.5 sacks. His best year was in 2019 in black and gold, when he dropped the quarterback 11.5 times. He's now 31 years old.

Anthony Barr, Minnesota Vikings

The four-time Pro Bowler and longtime Viking is reportedly not retiring despite playing in just four games last season and not joining a team until November (Minnesota's practice squad). He hasn't topped three sacks since 2015.

Laken Tomlinson, New York Jets

Tomlinson was Pro Football Focus' No. 53-ranked guard in pass blocking, six spots ahead of John Simpson, who New York signed to replace him. A former first-round pick (2015), Tomlinson was one of the league's highest-graded guards in San Francisco in 2020 and 2021.

Andrus Peat, New Orleans Saints

The Saints made Peat the 13th-overall pick in 2015 and he's been a starter for them ever since. Peat started at tackle but found a home at guard, where he went to three Pro Bowls. He wasn't slated to be a starter last year, but ultimately replaced first-round pick Trevor Penning as the starting left tackle for the final 11 games and played well. That kind of position flexibility is valuable.

Cody Whitehair, Chicago Bears

The Bears released Whitehair last month. A 2016 second-round pick, Whitehair made 118 starts over eight seasons in Chicago.

Dalton Risner, Minnesota Vikings

Risner signed a one-year deal a few weeks into last season and again proved to be a solid blocker, particularly in pass protection. Now he'll likely get a multi-year contract.

Halapoulivaati Vaitai, Detroit Lions

Vaitai signed a five-year, $50 million contract with the Lions in 2020. He's played in 31 games since due to injuries. A back injury, which led to surgery, cost him his entire 2022 season. He returned to play in six games (three starts) last season, but finished the year on injured reserve with a knee injury.

Xavien Howard, Miami Dolphins

Released by the Dolphins last week, Howard is a four-time Pro Bowler who was once a big-time playmaker for Miami and regarded as one of the game's top cornerbacks. He had 10 interceptions in 2020 and five the following year, but just two in the past two seasons.

Stephon Gilmore, Dallas Cowboys

The NFL Defensive Player of the Year in 2019 and a five-time Pro Bowler, Gilmore has been one of the game's best cornerbacks for nearly a decade. He'll turn 34 in September, but Gilmore still graded out as a strong cornerback last season in Dallas, earning PFF's 49th best grade.

J.C. Jackson, New England Patriots

The Patriots released Jackson in early March after trading for him midway through last season. Jackson started his career with a flurry, registering 25 interceptions in his first four seasons, but he hasn't been as effective the past two seasons and only nabbed one pick.

Steven Nelson, Houston Texans

Nelson is a longtime starter with the Chiefs, Steelers, Eagles, and Texans. Now 31 years old, he's still playing at a high level, ranking as the No. 41 cornerback in the NFL last season, per PFF.

S Jamal Adams, Seattle Seahawks

A three-time Pro Bowler, Adams struggled in coverage last season, earning a 29.9 PFF grade.

S Justin Simmons, Denver Broncos

Simmons is a two-time Pro Bowler, including last season. He's 30 years old and graded out as the No. 51-ranked safety.

S Quandre Diggs, Seattle Seahawks

Diggs was a three-time Pro Bowler from 2020-2022 but had a down year last year alongside Adams. He's started every game the past four seasons and had 14 interceptions the previous three seasons.

S Eddie Jackson, Chicago Bears

Jackson was a two-time Pro Bowler in 2018 and 2019 early in his career. The former Alabama product was a leader alongside Roquan Smith in Chicago, but he had a tougher 2023 season and was released in February.

S Micah Hyde, Buffalo Bills

A Pro Bowler in 2017, Hyde has been a big part of one of the NFL's most underrated safety duos in Buffalo. He's now 33 years old, but still ranked No. 66 by PFF.

S Marcus Maye, New Orleans Saints

Maye signed a three-year, $28.5 million contract with the Saints before the 2022 season began. He only played in 17 games for them, served a three-game suspension last season, and was released before free agency opened.

S Tracy Walker III, Detroit Lions

Walker had a solid 2023 season that ranked him at No. 88 among NFL safeties, according to PFF. He spent six seasons in Detroit and returned from a 2022 Achilles injury to play in all 17 games last year.
