Second in a series

Counting down to the beginning of the NFL free-agent signing period March 18, we will look at different position groups. Today, we look at the interior defensive line:

Big ticket players

D.J. Reader, Texans

Reader is one of the stoutest and most versatile defensive linemen in the game as he's capable of lining up all over the line of scrimmage. At 6-4, 337 pounds, Reader plays with a lot of power and athleticism and has sound technique. He may be too expensive for the Texans to retain and is expected to command an annual compensation of $11 million to $13 million. The Denver Broncos, Tennessee Titans and Buffalo Bills are among the teams interested in Reader, according to league sources not authorized to speak publicly. Barring a sudden change in strategy and making Reader a negotiating priority, he isn't expected to be back with the Texans. The Texans have made Reader contract offers, but started off way too low last offseason, initially at $6 million per year, for him to give them that kind of extreme hometown discount.

Javon Hargrave, Steelers

Run-stuffer who doubles as a disruptive pass rusher. Not tied to any defensive scheme and is capable of lining up in a 3-4 or a 4-3 alignment.

Jarran Reed, Seahawks

Reed is extremely talented, but is inconsistent and hasn't played as well over the past year as he did in 2018.

Jordan Phillips, Bills

Although Phillips recorded 9 1/2 sacks, he had just 19 additional pressures. He can play defensive end or tackle.

Shelby Harris, Broncos

Harris has emerged from obscurity to dominate for Broncos, but isn't expected to return.

Michael Brockers, Rams

Brockers is immovable inside. He isn't a pass rusher, but he's a stud as a run-stopper.

Ndamukong Suh, Buccaneers

Suh is getting older, but can still be counted on. Last season, the Buccaneers had the best run defense and that was largely because of him and Vita Vea.

Solid values

Gerald McCoy, Panthers

McCoy is still a good interior pass rusher. His run-stopping efficiency wasn't as good as it used to be last season.

Michael Pierce, Ravens

Pierce is a gritty, energetic run-stopper. He doesn't provide much pass rush.

Others to watch

David Onyemata, Saints

Texans' needs

If-when Reader leaves for a huge payday, it will create a giant hole in the Texans' defense. They may address this spot in the draft and elevate the role of Brandon Dunn, who was signed to a three-year, $!2 million contract. Reader is a unique defensive lineman. He'll be difficult to replace.
