Has a team ever gone 0 17?

No, a team has never gone 0-17 in the history of the National Football League (NFL). The longest winless streak by a single team in a regular season is 0-16, achieved by the Detroit Lions in 2008. During that season, the Lions were unable to win a single game and finished with no victories and 16 losses. This record demonstrates the difficulty of going winless throughout an entire NFL season.
