Dorazio spent a large part of his NCAA coaching career with the Huskies, and joined the team in 1982, reuniting him with head coach James.[4] In 1984, Dorazio's offensive line scheme helped the fourth-ranked Huskies to a victory over the Oklahoma Sooners in the 1985 Orange Bowl.[4] His tenure with the Huskies came to an end after a disappointing 1988 season and he was fired by James.[4]
After Buono was hired as the head coach of the BC Lions, Dorazio joined his coaching staff as the team's offensive line coach for the 2003 season.[6] Under his tutelage, Rob Murphy won the CFL's Most Outstanding Offensive Lineman Award in 2005 and 2006 and Dorazio won his third Grey Cup championship following the Lions' victory in the 94th Grey Cup.[6] He won his fourth title in 2011 with the 99th Grey Cup win, and Jovan Olafioye won the Most Outstanding Offensive Lineman Award in 2012.[6] Upon the hiring of Jeff Tedford for the 2015 season, Dorazio was not retained on the coaching staff.[8]
Saskatchewan Roughriders
On February 2, 2015, it was announced that Dorazio had joined the Saskatchewan Roughriders and Corey Chamblin's staff as the team's offensive line coach, reuniting him with former BC Lions offensive coordinator, Jacques Chapdelaine.[9] The Roughriders finished with a league-worst 3–15 record and the entire coaching staff was dismissed.[10]
BC Lions (second stint)
After Tedford resigned as the Lions' head coach and Buono returned as head coach, Dorazio was hired back to his coaching staff for the 2016 season.[11] He spent three seasons in his second stint as the Lions' offensive line coach.[6] He was not retained for the 2019 season by the team's new head coach, DeVone Claybrooks.[12]
Toronto Argonauts
On February 7, 2019, it was announced that Dorazio had joined the Toronto Argonauts as the team's offensive line coach, with Chapdelaine and Chamblin also serving on the team's coaching staff, the latter as head coach.[3] After a disappointing season for the team, Chamblin was fired and replaced by Ryan Dinwiddie,[13] who subsequently hired Stephen McAdoo as the new offensive line coach to replace Dorazio for 2020.[14]
Canadian university football
Dorazio was hired as the offensive line coach for the UBC Thunderbirds, but only spent spring training with the team as the 2020 U Sports football season was cancelled.[15] He was then hired by Simon Fraser on August 29, 2020, by interim head coach Mike Rigell, to serve as the team's offensive line coach and co-offensive coordinator.[16] However, their 2020 season was also cancelled and he did not coach for Simon Fraser.[17]
