Staley joins Detroit as the team's assistant head coach/running backs coach in 2021. This marks his 11th season as an NFL coach following a 10-year stint (2011-20) with the Philadelphia Eagles in various roles. After joining the Eagles as a special teams quality control coach in 2011-12, he took over the running backs in 2013 and added the assistant coach title in 2018. In his eight seasons overseeing Philadelphia's running backs, the Eagles produced the seventh-most rushing yards (15,765) and seventh-highest rushing average (4.40) in the NFL in that span. He helped the Eagles win Super Bowl LII and capture three NFC East division titles and four playoff appearances in his tenure. Prior to coaching, Staley enjoyed a 10-year playing career at running back with the Eagles (1997-2003) and Pittsburgh Steelers (2004-06), where he won Super Bowl XL. A native of West Columbia, S.C., he was selected by the Eagles in the third-round of the 1997 NFL Draft (71st overall) out of South Carolina.
