The United States Football League (USFL) was an American football league that played for three seasons, 1983 through 1985. The league played a spring/summer schedule in their three seasons. A fourth season, to be played in a traditional autumn/winter schedule, was set to commence before league operations ceased. The Michigan Panthers were the first USFL champions. The Philadelphia Stars won the second USFL championship, and after relocating to Baltimore, won the final USFL championship as the Baltimore Stars in effectively a rematch of the first USFL title game.
