End: Derrick Morgan, Kamerion Wimbley, Ropati Pitoitua, Lavar Edwards
Tackle: Jurrell Casey, Sammie Lee Hill, Mike Martin, Antonio Johnson, Stefan Charles
There are a few new faces in the defensive line unit that are sure to provide the team with some quality depth to rotate on and off the field at the very least.
Sammie Lee Hill steps into the Titans' vacated starting defensive tackle role with hopes of big things come from him. Hill was stuck behind Ndamukong Suh and Nick Fairley in Detroit, but should flourish with more playing time in Tennessee.
Mike Martin had a great rookie season as a third tackle and will reprise that role in 2013. At end, the coaching staff would like to play Ropati Pitoitua on first and second downs to help stop the run and give starters Kamerion Wimbley and Derrick Morgan some time to rest.
The biggest thing to look forward to with this unit is the development of Jurrell Casey and Derrick Morgan and how their play allows each to feed off one another.
Casey has been a beast in his first two seasons, but it's the third year that prospects really can make a big jump. If Casey can continue to improve his play, it will force double-teams and help open things up for pass-rushers.
With Morgan on the brink of breaking out as well, he is sure to be the prime beneficiary of Casey's double-teams. Teams will be forced to decide which of the two to double a per-play basis.
Much like the receiving corps, the Titans have a lot of quality depth in this group, but need someone to break out to make things work.
