The Detroit Lions hire Eagles' defensive backs coach Cory Undlin as defensive coordinator. Undlin spent five years in Philadelphia dating back to 2015. His most notable accomplishment came during the 2017 Super Bowl LII-winning campaign when the Eagles secondary only gave up 24 touchdown receptions. This marks the fewest touchdowns surrendered by an Eagles defense since 2008. That same year, the defense produced the fourth-most takeaways and ranked third in third-down defense.
Undlin reunites with Lions head coach Matt Patricia, as they both began their professional coaching careers as assistants with the New England Patriots in 2004. The 2004 Patriots finished the regular season with a 14-2 record and went on to defeat the Eagles in Super Bowl XXXIX.
Prior to his time in Philadelphia, Undlin spent three years with the Denver Broncos where he served as the defensive quality control coach in 2012 and the defensive backs coach from 2013-14. He also spent three years with the Jacksonville Jaguars, first as a defensive assistant in 2009, then as the defensive backs coach from 2010-11.
Undlin spent four seasons with the Cleveland Browns, starting as the team's defensive quality control coach in 2005-06, before being named the secondary/assistant special teams coach in 2007 and the defensive backs coach in 2008. The California Lutheran product has coached for a total of 16 years in the National Football League.
