No position group on Chicago's roster has been overhauled this offseason quite like the defensive line.
After the defense finished last season as the worst against the run in the NFL, general manager Phil Emery made it a point to improve not only the run defense but the pass rush.
Emery wasted little time once free agency began, signing defensive ends Lamarr Houston and Willie Young to long-term deals on the first day of free agency. Not long after those signings, Emery struck again by signing veteran Jared Allen.
All three immediately improve the team's ability to stop the run. Allen's presence alone should help boost the sack totals.
On the interior, veterans Jeremiah Ratliff, Nate Collins and Stephen Paea will work in a rotation with rookies Ego Ferguson and Will Sutton.
Ratliff and Paea are the likely starters at the 3-technique and nose tackle positions, respectively, but Collins, Ferguson and Sutton should all see ample playing time this season.
Rounding out the final two spots on the roster are two former Oakland Raiders castoffs.
David Bass showed flashes of his potential last season and should be able to carve out a niche as a situational pass-rusher. If he can improve his run defense, he may be able to push for more playing time this season.
Trevor Scott has bounced around the league since being drafted in the sixth round of the 2008 draft by the Oakland Raiders. He recorded 12 sacks during his first two seasons playing both linebacker and defensive end before an ACL injury ended his 2010 season.
He spent the 2012 season with the New England Patriots, recording three sacks, and played for the Tampa Bay Buccaneers last season. Despite being overshadowed by guys like Allen, Young and Houston, he's appreciative of the opportunity he's been given in Chicago.
"I was very fortunate the Bears called in the offseason," he told Arthur Arkush of ChicagoFootball.com. "Everything has gone pretty smooth. It was nice to get into an offseason program this year, just learning about what 'The Bear Way' is."
Scott does offer plenty of flexibility. He played defensive end and outside linebacker as well as contributed on special teams during his six NFL seasons.
Scott and Bass will be competing with guys like Austen Lane, Cornelius Washington, Tracy Robertson and Jamil Merrell for the final two spots, but their experience at defensive end and special teams should nab them the final spots.
