If the Titans want to "go" defense with their next head coach, they need to take a long look at Carolina Panthers defensive coordinator Sean McDermott.
The 39-year-old spent 11 seasons in Philadelphia with the Eagles coaching the secondary, linebackers and finally, the entire defense.
In 2011, Ron Rivera hired McDermott to be his defensive coordinator when he took the head coaching job in Carolina.
That year, the Panthers fielded one of the worst units in football. The defense finished 31st in both yards and points allowed per drive according to Football Outsiders.
In 2012, McDermott's group exhibited noticeable improvement, jumping to 20th in yards allowed per drive and 21st in points allowed per drive.
Everything came together in the NFC South-winning campaign of 2013.
Carolina's defense catapulted to eighth in yards allowed per drive and second in points allowed per drive. Although it's secondary got beat from time to time, the front seven was, arguably, the finest in the NFL.
The Titans have a formidable front seven of their own, headlined by defensive linemen Jurrell Casey, Karl Klug, Derrick Morgan and Akeem Ayers.
Oh, and McDermott runs a 4-3 defense, so Tennessee wouldn't have to labor through a time-consuming alignment switch.
