Combine the NFL’s poorest pass rush and 30th-ranked run defense with a new coaching staff and the result is predictable. When players report to training camp Thursday the Jaguars will have an overhauled defensive line. Nine of the 15 linemen on the roster are new. Among the projected four starters only Tyson Alualu returns from last August … and he’s playing a new position. Through veteran and rookie free agency and the waiver wire the Jaguars added size (six of the seven tackles are 300 or more pounds) and youth (only three are older than 27). “We’ve got some guys who have proven things in this league and we’ve got some really good young players who have to continue to develop” said defensive line coach Todd Wash who followed head coach Gus Bradley from Seattle. The most accomplished is defensive end Jason Babin who instantly became the Jaguars’ best pass rusher when he was acquired last November. He’s also the oldest (32) and had groin surgery last month. Babin will be joined in the end rotation by Alualu and last year’s Week 1 starters – Jeremy Mincey and Andre Branch. The interior was torpedoed and the newbies are Roy Miller Sen’Derrick Marks Brandon Deaderick and Kyle Love.
