The influence of new defensive line coach Shaun Nua: Navy finished 112th (out of 120) in the country in sacks last season and lost one of the best defensive linemen in school history in Jabaree Tuani. Jamel Dobbs, who started for the part of the 2011 season, left the academy after the season and Joshua Jones, who replaced Dobbs, decided to forego his senior year to concentrate on finishing the requirements needed to graduate. Nua, who played four years in the NFL and earned a Super Bowl ring as a rookie with the 2006 Pittsburgh Steelers, has an inexperienced group to work with in trying to get more pressure on opposing quarterbacks. Wes Henderson, the most experienced in the bunch, will not have the luxury of opposing offensive linemen double-teaming Tuani. Collin Sturdivant and Barry Dabney barely got on the field last season and Travis Bridges has been moved over from the offensive line.
