DE Leonard Williams, New York Giants

The sixth-overall pick in 2015 was traded across town from the Jets to Giants last offseason and could hit the market this offseason. He's one of the game's top talents in generating interior pass rush when healthy (seven sacks in 2016) but has missed 17 games the past two years.

DT Ndamukong Suh, Tampa Bay Buccaneers

At 33 years old and entering his 12th season, Suh is on the back nine of a once dominant career. He's played for three different teams the past three years and his sack production has dropped or stayed the same each of the past five seasons.

DE Chris Jones, Kansas City Chiefs

Jones is in the discussion as the league's best interior pass rusher, though Aaron Donald probably still edges him out. Jones has racked up a staggering 33 sacks in four seasons, including nine last year. He's expected to receive the franchise tag.

DE Arik Armstead, San Francisco 49ers

The massive 6-foot-7, 290-pounder broke out in his fifth season with 10 sacks after netting nine in the previous four years. He's likely not headed anywhere as the 49ers have expressed interest in retaining him and he's open to being tagged.

DE Derek Wolfe, Denver Broncos

Wolfe has been a strong player for the past eight years in Denver. He's started every game he's played in and is coming off a year in which he registered a career-high seven sacks. He has good size at 6-foot-5, 285 pounds and played with a lot of physicality.

DE Gerald McCoy, Carolina Panthers

The Ravens recruited McCoy last offseason but he chose to go to Carolina, where he logged five sacks and 37 tackles. It was his lowest sack production since 2012 but still a good year. The six-time Pro Bowler is now 32 years old.

DT Damon Harrison, Detroit Lions

"Snacks" Harrison has long been one of the game's premier run-stuffers. He's 31 years old and about to enter his 10th season.

DT Michael Brockers, Los Angeles Rams

Brockers, 29, is an athletic marvel at 6-foot-5, 305 pounds. He has been a reliable starter for nine seasons but has posted more than four sacks just twice in his career.

DT Dontari Poe, Carolina Panthers

Poe is a big, active force in the middle, standing in at 6-foot-3, 346 pounds. He has excellent feet for someone so heavy. Poe notched four sacks last year, a career-high since 2014.

DT Mike Daniels, Detroit Lions

After spending his first seven seasons in Green Bay, Daniels went to Detroit last year and had a tough year. He wasn't a full-time starter and missed seven games. His 10 tackles and one sack were both career-lows. The hard-nosed Iowa product will be looking for a rebound year at age 30.

DT Jordan Phillips, Buffalo Bills

Phillips broke out in a huge way last season with 9.5 sacks. He had 5.5 in his previous four years. Phillips played in all 16 games with nine starts. He could be a young (27) potential breakout candidate and has a massive frame at 6-foot-6, 341 pounds.

DT Timmy Jernigan, Philadelphia Eagles

The former Ravens second-round pick signed a big contract extension in Philadelphia and it hasn't panned out in the two years since. He's played in 13 games the past two seasons and registered two sacks. He missed six games last season.

DT A'Shawn Robinson, Detroit Lions

Robinson is a run stuffer in the middle who started nine of 13 games for the Lions last season. He's an Alabama product who could be a rotational player.

*DT Jarran Reed, Seattle Seahawks *

Reed is one of the game's better young defensive linemen, but his 2019 season was a struggle. He was suspended for the first six games for a violation of the personal conduct policy, then notched just two sacks in 10 games after posting 10.5 sacks the year prior.

DT Corey Liuget, Buffalo Bills

The former first-round pick (2011) is about to enter his 11th season and could land on his fifth team in five seasons. He has a smaller frame than most defensive tackles at 6-foot-2, 300 pounds and has missed 20 games over the past three seasons.

*DT Javon Hargrave, Pittsburgh Steelers *

Hargrave has quietly been a force up front for the Steelers. He's logged 10.5 sacks over the past two seasons and missed just one game over his four years in the league. At just 27 years old, he might cash in this offseason. Pro Football Focus graded him as the 10th-best defensive tackle last season.

DT D.J. Reader, Houston Texans

Another good, young defensive tackle, Reader will likely get a big payday. He's 6-foot-3, 347 pounds and a big-time run stuffer who provided some push (6.5 sacks in four seasons). Pro Football Focus ranked him as the sixth-best defensive tackle in the league last year.

DT Sheldon Day, San Francisco 49ers

Day has been a reserve throughout his career and played in all 16 games with one sack last season on a dominant 49ers defensive front.

DT Danny Shelton, New England Patriots

The former first-round pick didn't work out in Cleveland but had perhaps his best season yet last year in New England. He started 14 games and made a career-high 61 tackles and three sacks. He's a big run stopper at 6-foot-2, 345 pounds.

DE Jabaal Sheard, Indianapolis Colts

Sheard has been a consistent pass rusher since entering the league in 2011, registering 51.5 sacks for the Browns, Patriots and Colts. He's also been dependable, missing just 11 games in 10 years.

DE Michael Bennett, Dallas Cowboys

Bennett, 34, could retire this offseason after spending the past three seasons with four different teams. He still had 6.5 sacks last season with the Patriots and Cowboys, but he's more of a rotational player now (just one start).

DE Adam Gotsis, Denver Broncos

Gotsis emerged as a starter in his second and third seasons but started just three of nine games last year and registered 16 tackles and no sacks. The 27-year-old Australian is a high-motor player.
