Each Team's 2013 Breakout Player: AFC South

Colts: Coby Fleener- Fleener had a disappointing rookie season, especially considering the player the Colts drafted after Fleener -- tight end Dwayne Allen -- had a far better rookie season. Now, with Andrew Luck and Fleener reunited with their offensive coordinator at Stanford Pep Hamilton, big things could be on the horizon. If Fleener can stay healthy, I expect him to emerge as a serious weapon in 2013.
Other candidates: Greg Toler, Jerrell Freeman, and Darrius Heyward-Bey
Jaguars: Jason Babin- Yes, he's 33 years old and is on the back end of his career. However, Babin is in an ideal position under new coach Gus Bradley. He'll play the "leo" in the Jaguars 4-3 front, where he won't have any coverage responsibilities. Instead he can do what he does best; get to the quarterback.
Other candidates: Andre Branch, Chad Henne, and Tyson Alualu
Texans: Whitney Mercilus- Houston's 2012 first round pick didn't get a ton of time on the field but he was solid rushing the passer (six sacks). Mercilus replaces Connor Barwin who signed with Philadelphia in the offseason. That's a huge upgrade in terms of pass rush ability. Expect Mercilus to improve in his sophomore season and help teammate J.J. Watt wreak havoc on opposing quarterbacks.
Other candidates: Brooks Reed and Ben Tate
Titans: Kendall Wright- Wright had a productive rookie season in 2012 putting up a stat line of 64-626-4. He proved to be a reliable target and was consistent throughout the season. The Titans have a lot of depth at wide receiver and Wright is currently third on the depth chart. But, with Kenny Britt's history of injuries and off-field issues and rookie Justin Hunter struggling, I expect Wright to have break out year.
Other candidates: Jake Locker, Delanie Walker, Mike Martin, and Akeem Ayers
