2012 NFL Free Agent Defensive Linemen

Robert Mathis (IND) - DE - In a big offseason for the Colts, no defensive free agent is more important than Robert Mathis who has publicly stated his discontent with the lack of a long-term extension. The Colts defense relies upon quarterback pressure and Mathis is an enormous part of that. It'll be interesting to see if the Colts can scrounge together enough money to keep Mathis.

Antonio Garay (SD) - NT - Just as quickly as they lost Jamal Williams, they've replaced him at nose tackle with another Pro Bowl caliber player. It's crucial to the defense that they retain Garay to anchor the defensive front.

Calais Campbell (ARZ) - DE - Campbell is an important part of the defensive front for the Cardinals. His triangle numbers are off the charts and he has shown marked improvement overall as a football player over the past few years. His productivity would be hard to replace for a defense that can't afford to lose more talent.

Jason Jones (TEN) - DT - When healthy, Jason Jones is one of the league's better interior pass rushers. He has an explosive first step in getting upfield and disrupting a quarterback's ability to step up into a clean pocket. The Titans have allowed Albert Haynesworth and Jason Babin to leave at the top of their games, but re-signing Jones makes too much sense here.

John Abraham (ATL) - DE - The Falcons went out this past offseason to acquire Ray Edwards to improve the pass rush. Though Abraham is aging will lose a fraction of a step each year from here on out, losing his ability altogether would be a huge blow for the defense.

Cliff Avril (DET) - DE - Avril has been a member of the Detroit D-Line revolution under Jim Schwartz and Ndamukong Suh. He's an explosive pass rusher off the perimeterÑperhaps Detroit's best. Even so, the Lions line has had no problem getting to the passer regardless of who they play at defensive end; so while retaining their best exterior pass rusher may seem important, it's probably less so considering the coaching staff and the offensive attention the interior linemen garner.

Aubrayo Franklin (NO) - NT - It was little alarming that Franklin received as little interest as he did this offseason, receiving only a one-year deal from the Saints. He probably won't even garner as much attention as he did last season after moving to a less glamorous 40 front for interior linemen. Depending on his production this year, he could be a nice under-the-radar acquisition.

Sione Pouha (NYJ) - NT - The Jets aren't in a position with great depth in their front 7 where they can afford to allow productive starters to leave. Securing Pouha should be one of the organization's first objectives before they decide how to improve their roster through external acquisitions.

From that list there are loads of DE's available, one that jumped out at me was Andre carter of NE, he looked awesome as the season ended.
Wish Hali of Kansas city was available, that dude is a beast! Wonder if we got rid of will smith and sed Ellis we could get Mario Williams?

That NT from SD looks decent

Antonio Garay
