The Jacksonville Jaguars hired Mike Mularkey to help with the offense, but it seems like he is content to let things ride on the defensive side of the ball. According to Tania Ganguli of the Florida Times-Union, Mularkey has already retained two defensive assistants, including coordinator Mel Tucker.
Jaguars defensive line coach Joe Cullen will return to Jacksonville's staff next season, according to a source. The Jaguars hired Cullen before the 2010 season and tasked him with fixing a unit that had 14 sacks in 2009. Cullen's return is the second defensive coach known to be returning to Jacksonville from last season's staff. New Jaguars head coach Mike Mularkey also retained defensive coordinator Mel Tucker.
Mularkey does not have a lot of experience with the defensive side of things, so it makes sense that he would try to establish some continuity in this way.
