Jared Cook
The second-year pro was drafted to add a vertical dimension to the Titans' tight end corps. However, Cook failed to crack the lineup or make a significant contribution to the team's aerial attack. With the Titans' postseason hopes hinging on the development of the passing game, Cook needs to quickly emerge as a difference-maker for Vince Young.
Stephen Tulloch
The undersized headhunter becomes the face of the Titans' defense after the offseason departure of Keith Bulluck. Though Tulloch stands less than 6 feet tall, his presence looms large in the middle as he acts a tackling machine between the tackles. He has ranked among the team's leading tacklers the past two seasons, including posting a team-high 94 solo stops a year ago. Given his outstanding instincts and relentless motor, Tulloch will continue to wreak havoc on foes attempting to find running room against the Titans.
Young can flourish
Vince Young isn't going to become an elite fantasy quarterback, but his versatile skill set does make him a potentially valuable reserve or matchup-based starter this season. It doesn't hurt to have a talented and explosive running back like Chris Johnson in the backfield with him, either.
Three pivotal games
Oct. 31 at San Diego
If there's one game from last season that Vince Young would like a do-over on, it's probably the Titans' 42-17 home loss to the Chargers in Week 16. Young threw two interceptions and lost a fumble on his way to a passer rating of 11.9. He'll be sure to improve upon those dreadful numbers this time around.
Nov. 28 at Houston
If history is any indication, the Titans will look to run at the Texans from every which way. Chris Johnson had his best game (284 yards from scrimmage, including 197 rushing) against Houston in Week 2 last season, and Young always gets up for games in his hometown. Both teams will jockey for position in the AFC South.
Jan. 2 at Indianapolis
The last time Young faced the Colts in a season finale was 2007, when he completed 14 of 18 passes for a 103.0 passer rating and helped Tennessee earn a playoff spot. That was the start of a long roller-coaster ride for Young that currently has him back as the starter. Who knows? Maybe a win here will get Tennessee into the postseason again.
