In January 2012, the Broncos announced their new defensive coordinator, a former linebacker, who retired from playing in what year?
Jack Louis Del Rio Jr. (born April 4, 1963) is head coach of the Oakland Raiders of the National Football League (NFL). A linebacker for four NFL teams between 1985-1996, he played both football and baseball for the University of Southern California Trojans.
Del Rio began his coaching career as an assistant strength and linebacker coach with the New Orleans Saints. He was the linebacker coach on the Super Bowl XXXV-winning Baltimore Ravens, and defensive coordinator on the Carolina Panthers and the Denver Broncos. He served as head coach of the league’s Jacksonville Jaguars from 2003 until 2011, the second in team history, and took a second head coaching job, this time with the Raiders in January 2015.
