The Eagles already had two holes to fills on their coaching staff.
Now there will be another one.
The Eagles are losing defensive backs coach Cory Undlin to the Detroit Lions, where he will be named their defensive coordinator, per ESPN’s Field Yates.
Now Pederson and defensive coordinator Jim Schwartz will need to find a new defensive backs coach.
Undlin was a holdover from Chip Kelly’s staff, hired in 2015 and Pederson kept him on in 2016. The Lions job makes sense for Undlin considering both he and Detroit coach Matt Patricia got their start with the New England Patriots back in 2004.
There has been both good and bad with Undlin over the last few years. On one hand, he helped turn a seventh-round pick (Jalen Mills) into a decent starting cornerback in the NFL and helped the Eagles defense survive despite constant turnover due to injuries. His best work came last year when the Eagles lost Rodney McLeod, Ronald Darby, Mills and, for parts of the season, Sidney Jones but Undlin was able to get the young trio of Rasul Douglas, Avonte Maddox and Cre’Von LeBlanc integrated and helped the Eagles make the playoffs.
He also had Craig James ready to come in for his second play of the season, and the first against the Packers, on the last play of the game against Aaron Rodgers… and James had a game-winning pass breakup.
On the other hand, other young corners — namely Maddox and Jones — didn’t show enough progress after multiple seasons under Undlin’s tutelage
In October, Pederson said of Undlin: “It’s a credit to Cory and getting these guys prepared and guys that we just really bring in week one, not on your practice squad or whatever.But yeah, he’s done a great job preparing these guys and that’s part of our jobs as coaches, is you’re coaching everybody. He’s done a good job doing that.”
Now, they’ll begin a search to find his replacement.
One option: Matt Burke, the former Dolphins defensive coordinator who is on staff already as a defensive special assistant, though his history is mostly with coaching linebackers.
