The Philadelphia Eagles have announced several changes to their 2015 coaching staff. Here's a quick overview:

• Eagles hire Denver Broncos defensive backs coach Cory Undlin as Philadelphia's new defensive backs coach. (Undlin background here). Former defensive backs coach John Lovett moves to the Eagles pro scouting department.

• Eagles promote assistant tight ends coach Justin Peelle to tight ends coach. Former tight end coach Ted Williams moves to the Eagles pro scouting department.

...

The news of Philadelphia hiring Undlin leaked out earlier on Monday evening. Here's what we wrote about him at the time:

"Undlin became available when the Broncos fired former head coach John Fox last week. The 43-year-old Minnesota native has been coaching in the NFL since 2004. He got his start as a defensive coaching assistant with Bill Belichick and the New England Patriots before moving on to jobs with the Cleveland Browns, Jacksonville Jaguars, and most recently the Broncos.



Undlin served as Denver's defensive backs coach starting in 2013. During that time, he's worked with the likes of Dominique Rodgers-Cromartie, Champ Bailey, Chris Harris Jr., Bradley Roby, Aqib Talib, and Rahim Moore (who will be a free agent this offseason)."

Philadelphia's defensive backs have struggled since Lovett was originally hired by Philadelphia in 2013. It's hard to blame the all of the struggles on coaching because the Eagles secondary talent has been sub-par, but a change like this can't hurt.

...

Peelle's promotion to tight ends coach was really only a matter of time. It was clear he was a natural successor to the position. Peelle joined the Eagles in 2013 as the assistant tight end coach after the Eagles moved Ted Williams from running backs coach to tight ends coach. The 35-year-old Peelle spent the past two seasons getting seasoned for the job, so he should be ready. With the group of Brent Celek, Zach Ertz, James Casey, and Trey Burton, the Eagles have a pretty good group of tight ends.

Williams originally joined the Eagles as a TE coach in 1995 before switching over to running backs coach from 1997-2012. Williams, along with Duce Staley, was one of the only coaches to survive Philadelphia's house cleaning when Andy Reid was fired and Chip Kelly was hired.

...

Lovett and Williams being moved into the Eagles pro scouting department seems like an effort by the Eagles to fire them without having to actually, you know, fire them.

...

It remains to be seen if more changes are coming. Offensive coordinator Pat Shurmur interviewed for the Oakland Raiders and Buffalo Bills head coaching vacancies but those positions have since been filled. It looks like he will be back.

Quarterbacks coach Bill Musgrave is reportedly a serious candidate for the Raiders' offensive coordinator job, however, so that's something to watch.

UPDATE: Raiders hire Musgrave to be their new offensive coordinator.
