What do the changes on D mean for the Jags?

The Jacksonville Jaguars were arguably the worst team in the National Football League a season ago, and as new head coach Gus Bradley attempts to right the ship in Jacksonville, one of his primary challenges is improving a defense that ranked 30th in the NFL in 2012.

Bradley isn’t wasting any time making changes on that side of the ball. The first was installing the scheme that helped get Bradley the job in the first place.

Bradley is a proponent of a 4-3 “under” front, where the defensive line shifts away from the strong side of the formation. As Jene Bramel of FootballGuys pointed out for The New York Times, the weak-side defensive tackle aligns between the guard and tackle, while the weak-side end plays outside the tackle (often well outside).
