The 1978 Utah State Aggies football team represented Utah State University during the 1978 NCAA Division I-A football season as a new member of the Pacific Coast Athletic Association (PCAA).[1] Led by third-year head coach Bruce Snyder, the previously-independent Aggies played their home games on campus at Romney Stadium in Logan, Utah. They opened with five wins and finished with a 7–4 record (4–1 PCAA, tied for first).[2]
A noteworthy game was against Idaho State (of nearby Pocatello), the first college football season-opener played in Japan.[3] [4]
