Eight in the Box: Breakout player

Who is one potential breakout player for each AFC South team in 2013?

Houston Texans: Receiver DeVier Posey would be the guy, but he is recovering from a serious Achilles injury suffered in the playoff loss in New England. It’s a veteran roster with known commodities at most spots. Brandon Brooks played some in the final six games of the season. The second-year right guard has shed some weight and will be in far better position to unseat fellow 2012 draft pick Ben Jones for the starting job.

Indianapolis Colts: In Oakland, receiver Darrius Heyward-Bey endured frequent coaching, coordinator and quarterback changes. The hope is some stability will help the him settle in and become more regularly productive in Pep Hamilton’s offense with Andrew Luck as his quarterback. Perhaps in a new setting, Heyward-Bey's speed will translate better into game speed, and he can grow into a target better able to make catches outside his frame.

Jacksonville Jaguars: We’ll have to see just how much the Jaguars add at cornerback in the draft, but second-year man Mike Harris is in prime position to establish himself as a primary contributor. He currently rates as the No. 1 corner on the team where Alan Ball is second. However, Harris is 5-foot-10, 188 pounds, and new coach Gus Bradley is coming from Seattle, where his defensive system put a premium on big corners.

Tennessee Titans:Outside linebacker Akeem Ayers certainly made his share of plays in his second season. Near the end he was used more and more as a pass-rusher, and I believe the Titans are considering him as one of their three top rushers -- thus the team’s lack of urgency in adding another defensive end. New senior defensive assistant Gregg Williams is more rush-focused than coordinator Jerry Gray, a former defensive back. That could help Ayers take another big step.
