The Detroit Lions are installing a series of changes to their defense under new coordinator Teryl Austin.

Though the base scheme remains a 4-3, they are bringing more pressure from each level of the defense. They are blitzing from several angles and positions. They are mixing up the fronts.

They are doing all of this to confuse offenses. And if early offseason practices are any indication, defensive end Devin Taylor will play a key role in the new system.

With Jason Jones still easing his way back from knee surgery, Taylor has repped with the first unit opposite Ezekiel Ansah. He's also repped some at defensive tackle in various subpackages, including in what appears to be the nickel look.
