The 1980 NFL season was the 61st regular season of the National Football League.
After the league declined to approve the proposed move by the Raiders from Oakland, California to Los Angeles, the team along with the Los Angeles Coliseum sued the NFL for violating antitrust laws. A verdict in the trial would not be decided until before the 1982 NFL season.
Meanwhile, the season ended with Super Bowl XV when the Raiders defeated the Philadelphia Eagles, becoming the first Wild Card playoff team ever to do so. Taken from https://en.wikipedia.org/wiki/1980_NFL_season
