Leroy Hill, LB
Hill, who started 12 games this season for the Seahawks, is a tough linebacker who can provide both pass coverage and run support.
The Patriots could use his pass coverage. Quarterbacks completed 60 percent of their passes against him, which was good for second best in the NFL for linebackers who played at least 25 percent of their teams snaps, according to ProFootballFocus.com.
The eight-year veteran has 511 career tackles, 20 sacks, 11 passes defensed and eight forced fumbles. But he's run into trouble with the law. He was arrested for the fourth time Jan. 30 after allegedly assaulting his girlfriend and holding her against her will at his home.
