With the hiring of Nick Sirianni now official, the next goal for the Eagles this offseason is to put together Sirianni's staff. The team has already quickly decided who his defensive coordinator is going to be, as it is being reported that Jonathan Gannon will be joining the Birds for the role.
Gannon was with Sirianni in Indianapolis these past few seasons, and has been working on the coaching side of football for 14 years. Here's what his resume looked like heading into his interview with the Eagles:
Volunteer Student Assistant Louisville (2003-2005)
Graduate Assistant at Louisville (2006)
Defensive Assistant/Quality Control with the Atlanta Falcons (2007)
Defensive Assistant/Quality Control with the Tennessee Titans (2012–2013)
Assistant Defensive Assistant/Quality Control with the Minnesota Vikings (2014–2017)
Defensive Backs/Cornerbacks with the Indianapolis Colts (2018–2020)
The young coordinator oversaw a Colts defensive backfield that was well respected across the NFL and always towards the top of the league in least amount of passing yards against. It's likely that Gannon will keep the Eagles in a 4-3 defense, as that was the defense that he was accustom to back in Indianapolis.
Given his age the Eagles are likely hoping he can last in Philadelphia for a few years before the possibility of any head coach interest from opposing teams.
