The Eagles have lost defensive backs coach Cory Undlin to Detroit, as the Lions have hired him to be their new defensive coordinator, according to an ESPN report. 

Undlin has been with the Eagles since 2015, and was one of only a handful of coaches that kept their job once Chip Kelly was let go. Of all the defensive coaches besides Schwartz, Undlin had the most input on what happened with the defense. 

Undlin’s track record with the Eagles is in many ways a complicated one. On one hand, the Eagles’ young cornerbacks — such as Sidney Jones, Rasul Douglas and others — have not exactly developed into every snap starters just yet. The secondary routinely gave up big plays down the field, with the secondary catching the brunt of the blame. 

Undlin, however, was put in a situation where his cornerbacks were left on islands the majority of the game, a result of the defensive system that Schwartz ran. Undlin also saw his unit change almost weekly due to injury. Judging his time with the Eagles is a lot like judging Schwartz’s time — it hasn’t always been pretty, but the results have been there. 

The question is, what happens now?

With Undlin gone, it is possible that cornerback Jalen Mills won’t be back. Mills was Undlin’s favorite cornerback and it wouldn’t be surprising if Mills followed Undlin to Detroit, as he is a free agent his offseason. Even with Schwartz back, it is likely the personnel in the secondary will change now that Undlin is gone. 

For the Eagles, their search for a new defensive backs coach begins. It is unlikely that they promote from within. More than likely, this decision will be made by Schwartz, who basically runs the defensive side of the ball.
