The 1975 World Football League season was the second and last season of the World Football League. The 1975 season was to be an 18-game season over a twenty-week schedule.
The WFL returned with a massive overhaul under new commissioner, Christopher Hemmeter. Four of the inaugural twelve teams returned from the 1974 season: The Hawaiians, Southern California Sun, Philadelphia Bell and Memphis Southmen, as did the Shreveport Steamer and Charlotte Hornets, who moved from Houston and New York City, respectively, midway through the 1974 season. New WFL teams replaced folded teams in Birmingham (where the Vulcans replaced the league champion Americans), Portland (where the Thunder took the place of the Storm), Jacksonville (the Express took over for the Sharks), and Chicago (the Winds stepped into the place of the Fire). One new market was added when the Florida Blazers moved to become the San Antonio Wings; the Blazers and Detroit Wheels were not replaced in their home markets.
The Winds were expelled from the league five games into the season. They had essentially bet their existence on an attempt to woo New York Jets quarterback Joe Namath as its starting quarterback. The Winds all but promised that Namath was coming, and their failure to deliver him was a severe blow to the league's credibility. It also prompted TVS Television Network, the league's TV partner, to cancel its WFL coverage prior to the regular season, leaving the league untelevised with the exception of some local television.
