The San Francisco Demons were part of a failed professional American football league which played one season in what year?
XFL The XFL was a professional American football league which played one season in 2001. It was operated as a joint venture between the World Wrestling Federation (WWF, now known as WWE) and NBC. The XFL was conceived as an outdoor football league that would take place during the NFL off-season, and promoted as having fewer rules and encouraging rougher play than other major leagues. The league had eight teams in two divisions, including major markets and those not directly served by the NFL, including Birmingham, Las Vegas, Los Angeles, Memphis, and Orlando. The XFL operated as a single entity, with all teams centrally owned by the league.
1928 NFL season The 1928 NFL season was the ninth regular season of the National Football League. The league dropped to 10 teams after both the Cleveland Bulldogs and the Duluth Eskimos folded before the season. The Buffalo Bisons also had a year out from the league, and the Rochester Jeffersons, after missing two seasons of play, finally folded. The Detroit Wolverines were an expansion club. Meanwhile, the Providence Steam Roller were named the NFL champions after finishing the season with the best record.
