Coordinator Jim Schwartz helped produce an elite defense in the Eagles 2017 Super Bowl season, but the team regressed to average over the last two years with poor play in the secondary.

They traded for cornerback difference maker Darius Slay from Detroit, and have also spent on the defensive line with tackle Javon Hargrave.

As usual, this is a defense built up front with stars Brandon Graham and Fletcher Cox, and the team is hopeful for a breakout from Derek Barnett in his fourth season.
