Eagles Make Nick Sirianni's Inaugural Coaching Staff Official The Eagles finalized their 2021 coaching staff under first-year head coach Nick Sirianni on Thursday Author: It's 23 deep and the organization confirmed the group on Thursday. The major hires - Shane Steichen as offensive coordinator, Jonathan Gannon as defensive coordinator, and Michael Clay as special teams coordinator - had been known for quite some time. There were, however, some interesting final tweaks to the group, notably former quarterback Alex Tanney, who retired as a player from the New York Giants two days ago, coming on as an offensive quality-control coach. Steichen arrives in Philadelphia for a reunion with Sirianni. The two were assistants together with the San Diego/Los Angeles Chargers before Sirianni left for the OC job under Frank Reich in Indianapolis.
