Sirianni played wide receiver at Division IIIMount UnioninAlliance, Ohio, winning national championships in 2000, 2001, and 2002.[4] Though a calf injury and compartment syndrome nearly ended his playing career as a sophomore,[5] Sirianni started for three years.[4] As a senior in 2003, he had 998 yards and 13 touchdowns[6] and graduated with a degree in education.[7]
In2009, Sirianni was hired as offensive quality control coach for the Kansas City ChiefsbyTodd Haley, the new head coach of the Chiefs.[6] Sirianni and Haley got to know each other when they attended the same YMCA when Sirianni was in college and Haley was wide receivers coach for the Chicago Bears.[10] Sirianni was retained under new coach Romeo Crennel and was promoted to wide receivers coach in Crennel's only season as the Chiefs head coach. Sirianni was not retained under new head coach Andy Reid.[11][12]
After Reich became the head coach of the Indianapolis Colts in 2018, he hired Sirianni as offensive coordinator.[14] Sirianni developed a close relationship with Reich, though unlike some head coaches, Reich chose to call the team's plays rather than delegate the responsibility to Sirianni.[15] During his three years as offensive coordinator with the Colts, Sirianni had a different starting quarterback each year, working with Andrew Luck, Jacoby Brissett, and Philip Rivers. The Colts made the playoffs twice and finished 10th, 19th, and 12th in offensive DVOA, a measure of offensive success.[4]
On January 24, 2021, Sirianni was hired to become the head coach of the Philadelphia Eagles after the firing of Doug Pederson.[16][17] Two months later, the Eagles traded quarterback Carson Wentz to the Colts, leaving former second-round pick Jalen Hurts as the presumed starter.[18] Sirianni put together a staff of young coaches, including defensive coordinator Jonathan Gannon and offensive coordinator Shane Steichen, both of whom had previously worked with Sirianni. Although much of Pederson's staff was replaced, Sirianni retained veteran offensive line coach Jeff Stoutland.[19]
On September 12, 2021, Sirianni made his regular-season head coaching debut against the Atlanta Falcons and led the Eagles to a 32–6 win.[20] Despite a 2–5 start, Sirianni concluded his first season as head coach with a 9–8 record and a wild card berth.[21] The Eagles lost in the Wild Card Round of the playoffs to the Tampa Bay Buccaneers 31–15, who themselves would lose the following week.[22] Sirianni was the only first-year coach to lead a team to the playoffs in the 2021 NFL season,[23] and the third Eagles head coach to make the playoffs in their first year as head coach, joining Chip Kellyin2013 and Ray Rhodesin1995.
The 2022 Eagles compiled a 14–3 record in the regular season, earning the NFC East division championship and a first-round bye in the playoffs.[24] The Eagles became the first team since the 1989 Minnesota Vikings to record at least 70 sacks,[25] led the league in fewest passing yards allowed, and set a franchise record for wins and points scored in a season.[26] In the playoffs, Sirianni led the Eagles to their fourth Super Bowl in franchise history after a 38–7 Divisional Round playoff victory against the New York Giants, and a 31–7 NFC Championship win against the San Francisco 49ers.[27][28] The Eagles lost to the Kansas City ChiefsinSuper Bowl LVII 38–35.[29]
During the 2023 NFL offseason, Sirianni lost both offensive coordinator Shane Steichen and defensive coordinator Jonathan Gannon, both of which received head coaching jobs with the Indianapolis Colts and Arizona Cardinals respectively.[30] The 2023 Eagles once again compiled a 10–1 regular season record to start the season, but experienced a late season slide and finished with a 1–5 record under Sirianni and ultimately lost out on the NFC East Division title and the #2 seed in the NFC playoffs to the Dallas Cowboys on the last week of the season.[31] Sirianni became the first head coach in NFL to experience a 1–5 record to end the season and make the playoffs. The Eagles were ultimately eliminated by the Tampa Bay Buccaneers in the Wild Card Round of the 2023 NFL Playoffs.[32] Sirianni was widely blamed for both the offensive and defensive regression of the Eagles in 2023.[33] In particular, Sirianni caused a significant controversy when he removed defensive coordinator Sean Desai from defensive play calling and passed them onto former New England Patriots defensive coordinator and Detroit Lions head coach Matt Patricia, a move that ultimately backfired and led the Eagles to finish second to last in total defense.[34][35] Sirianni ultimately fired Desai, Patricia, and offensive coordinator Brian Johnson after the Eagles season ended.
During an interview with Rich Eisen, Sirianni revealed that he grew up a fan of the Pittsburgh Steelers, owing to his family having roots in the Pittsburgh area.[42]
