Coach Gus Bradley said the Jaguars will play a hybrid of 4-3 and 3-4.
Expect the Jaguars' defense to resemble the Seahawks' system Bradley implemented as Seattle's defensive coordinator. This means a lot of 4-3 looks, as the Seahawks lined up in a 4-3 base package 51 percent of the time in 2012. The Seahawks often used a 4-3 "Under" defense, where the strong-side linebacker is outside the tight end and the "Leo" rushes the quarterback's blind side. Jason Babin is expected to play the "Leo" role for Jacksonville this season.
