He previously served in the same capacity with the Detroit Lions during the 2021 and 2022 NFL seasons, and with the Philadelphia Eagles in various assistant coaching roles from 2011 to 2020.

Staley attended Airport High School in West Columbia, South Carolina and was an All-State wide receiver, and played running back sparingly.

Entering the 2003 season, Staley held out of training camp in an attempt to bargain for a new contract, as he was in the last year of his deal.

[5] With Correll Buckhalter coming back from a torn anterior cruciate ligament (ACL) and Brian Westbrook entering his second season, the Eagles decided not to budge.

[7] He instantly became the number one running back for his new team, and was seen as the eventual heir apparent for Jerome Bettis, who at the time had the sixth-most career rushing yards in NFL history.

He only scored one touchdown however, as Bettis took most goal-line carries, and eventually took over the starting job since Staley missed six games.

[9] The Steelers signed former Packers' running back Najeh Davenport the next day, and deactivated Staley for the rest of the season.

At halftime, Staley was escorted onto the field by former teammates for his retirement celebration featuring a brief ceremony and two highlight videos.

[13] After the departure of Andy Reid, Staley remained on the new staff with Chip Kelly and was promoted to the team's running backs coach.

He planned to communicate with the team virtually during his quarantine, and he relinquished day-to-day head coaching duties to Staley in the interim.

He underwent an innovative rehabilitation period prior to the 2001 season to become the first skill position NFL player known to return from a Lisfranc injury.
