NFL 2015: Ranking each defense from 32-1

30. Tennessee Titans

The Titans went 2-14 last season. When you have a record like that, very few things about your team are any good. In the case of Tennessee, defensive lineman Jurrell Casey was one of the main highlights of an otherwise lackluster unit, racking up 68 tackles and five sacks with precious little help around him. Going into 2015, the defense still has plenty of questions.

The big upgrade during the offseason was the signing of outside linebacker Brian Orakpo. The former Washington Redskins star has talent as evidenced by his 40 career sacks in six seasons, but health and consistency have been issues. The rest of the linebacker corps is nothing special, although the return of Zach Brown form an injury-plagued season can only help.

New defensive coordinator Dick LeBeau is an NFL Hall of Famer and a coaching legend, but he will have his hands full in the secondary. Safety Michael Griffin is years past his prime, while Da’Norris Searcy is trying to learn a new system. Jason McCourty is an average corner and Perrish Cox is middling, while both Blidi Wreh-Wilson and Coty Sensabaugh are not legitimate NFL players.
