Since Joe Philbin was announced as the new head coach of the Miami Dolphins last week, the team's staff, which includes a number of former Cowboys contributors, has been in a state of flux.
On Monday, the departure of former Dallas assistant Todd Bowles was made official, as he was announced as the new secondary coach of the Philadelphia Eagles.
Bowles served as the Dolphins' interim head coach after Tony Sparano was released with three games remaining in 2011.
The former Cowboys defensive backs coach twice interviewed with Jerry Jones for the team's head coaching vacancy, in 2007, before Wade Phillips was hired, and again in 2011, when the job eventually went to Jason Garrett.
Bowles, who had joined Bill Parcells' staff in 2005, worked for Phillips in 2007. After Parcells took over as Dolphins team president in 2008, Bowles took his talents to South Beach along with well over a dozen former Dallas players, coaches and front office staff members, including Jeff Ireland, the former Cowboys head scout who remains as Miami's GM.
Sparano, once Cowboys assistant head coach and offensive coordinator, has signed on to run the New York Jets' offense.
For the Cowboys' division rivals in Philadelphia, Bowles will work under Juan Castillo, who is returning for a second season as Eagles defensive coordinator following as extended stint as the team's offensive line coach.
