With the news of Doug Pederson being unofficially named the next Eagles head coach, his staff will now begin to take shape. Don Banks of Sports Illustrated is reporting that the Eagles are interested in bringing in former Lions head coach and former Bills and Titans defensive coordinator Jim Schwartz as Pederson's defensive coordinator, along with other teams:
Source says Eagles have interest in Jim Schwartz as defensive coordinator. Do not know if he's Doug Pederson's DC choice, or the team's?— Don Banks (@DonBanks) January 14, 2016
Source says Jim Schwartz has offers to serve as defensive coordinator from multiple teams. But not known if Eagles have made an offer yet.— Don Banks (@DonBanks) January 14, 2016
Schwartz is an experienced defensive coordinator, having spent eight years in Tennessee with Jeff Fisher before taking over the 0-16 Lions. After he was fired from Detroit following the 2013 season, he was Doug Marrone's defensive coordinator in Buffalo, In his lone season with the Bills in 2014 they finished 4th in scoring and yards.
Schwartz parted ways with the Bills after the hiring of Rex Ryan and was unemployed in 2015, but is reportedly waiting to see if a return to the Titans would be possible. This interest in Schwartz clearly signifies a philosophical shift to the 4-3 defense, with Schwartz having run it and the Wide 9 variation of it successfully throughout his career.
UPDATE: Jeff McLane of the Inquirer also reports that Schwartz and Mike Pettine, who Schwartz succeeded in Buffalo after Pettine was hired as Browns head coach, are potential defensive coordinators.

We'll have more as things inevitably develop.
