Doug Pederson is gathering a staff.

On the heels of Pederson being unofficially named the next head coach of the Philadelphia Eagles, a staff is beginning to be built.

Don Banks, Sports Illustrated, reports that the Eagles have interest in former Detroit Lions head coach Jim Schwartz to be their defensive coordinator.

Schwartz, 49, is also the former defensive coordinator of the Buffalo Bills along with the Tennessee Titans.

He spent 8 seasons under Jeff Fisher with the Titans running their defense before being hired by the Lions after they finished their 0-16 season.

Schwartz was soon fired and took over a Bills defense with Doug Marone.

Schwartz would bring in a 4-3 base defense and believes in employing a Wide-Nine technique for his defensive line that allows the defensive ends to get a pure pass rush.

As Banks notes, other teams are interested in Schwartz and it's unknown if Pederson or Eagles brass are after Schwartz.

Jeff McLane, Philadelphia Inquirer has also floated Mike Pettine as a possibility to run the defense.

Stay tuned.
