1988 Phoenix Cardinals season
The 1988 Phoenix Cardinals season was the franchise's 69th season in the National Football League and the first season in Phoenix. The Cardinals would match their 7–8 record from 1987, but finished with one more loss, going 7–9, as 1987 was a one-game strike shortened season, and 1988 was a full 16 game season. The Cardinals move to Phoenix marked the first time an NFL team called a place in Arizona home.
