NASHVILLE, Tenn. -- While reiterating that his coach and general manager are safe, Tennessee Titans CEO and president Tommy Smith made it clear that plenty of players are not.

"The roster is going to look a lot different next year," Smith told The Tennessean. "Players need to be playing to the best of their abilities right now, and that will determine their future. There may be some players whose contracts might be up, but that doesn't mean they're not going to be here. There may be some players with multiyear contracts, but that doesn't mean they're going to be here."

Underachieving left tackle Andy Levitre could be one player at risk. He signed a six-year, $47 million contract in 2013 and hasn't played like a big-dollar free agent is expected to. Tennessee can part with struggling right tackle Michael Oher for no additional money after paying out $6 million to him in 2014.

Free-agents-to-be include quarterback Jake Locker, receiver Nate Washington, injured left tackle Michael Roos and linebacker Derrick Morgan.

Even with a big free-agent class and a draft, there is only so much roster turnover a team can pull off in one offseason.

But the 2015 roster will be stocked with more players coach Ken Whisenhunt feels are better for building a team that fits the schemes and culture he wants.
