ALLEN PARK -- Multiple-front defenses are a trendy concept in the NFL. But their success has been undeniable, leading to young coordinators such as Gus Bradley and Mike Pettine getting head coaching jobs in the past year.

Bradley was hired by the Jacksonville Jaguars in 2013 after orchestrating the Seattle Seahawks defense for four seasons. The continuation of his scheme helped the Seahawks have the top-ranked unit in the league last season.

This season, the Detroit Lions are jumping on the trend of multiple fronts, hiring long-time secondary coach Teryl Austin to install a more complex, aggressive scheme.

Austin comes from Baltimore, another multiple-front team. Listed as a 3-4 defense, the Ravens played with principles more in line with a 4-3, especially at the line of scrimmage. Despite losing several key starters from their 2012-13 Super Bowl squad, the team still managed to finish 12th in total and scoring defense last season.

Detroit defensive end Jason Jones, who played the 2012 season under Bradley in Seattle, sees similarities in the two defenses and is thrilled with the changes Austin is bringing.

"We've got a lot of stuff that (Austin) brought from the Ravens, as well as his background with Seattle (secondary coach 2003-06)," Jones said. "I like the multiple fronts. It keeps the offense on their toes. We're not predictable. We'll come out there in different sets and we can run different things. Everybody, especially on the defensive line, are interchangeable."

Cornerback Cassius Vaughn is a newcomer to the Lions this year. He spent the past two years with the Indianapolis Colts, where Chuck Pagano is the coach. Austin lists Pagano, previously the Ravens defensive coordinator, as one of his mentors.

Asked if there are any similarities to what the Colts do on defense and what the Lions are installing, Vaughn said yes, but Austin's scheme has "a bit more spice."

Vaughn feels Detroit's defensive front, in Austin's scheme, will benefit the secondary similar to way it has in Seattle.

"We've got some of the best pass rushers in the league, period," Vaughn said. "With the front seven we have, it's going to be a lot easier for the secondary to play how we want to play. (Ndamkuong) Suh, Nick Fairley, (Ezekiel Ansah), we've just got guys and guys, rotating in, and that's a big help for the secondary. Look what it did for Seattle."

All Seattle did last season was lead the league in opposing quarterback rating, yards per completion and interceptions. Not bad. Obviously, with All-Pros Richard Sherman and Earl Thomas roaming the defensive backfield, all things aren't created equal.

Still, with increased and varied pressure packages from the front seven -- as well as a more aggressive coverage scheme, which relies more on pressing receivers at the line of scrimmage -- the Lions should be able to improve on a defense that ranked 23rd against the pass in 2013.
