In the 2004–05 season, the club's 60th anniversary and 20th as independent club, the team won the league title, by having the best record during the regular season, and the Swedish Championship. That particular year was notable because the National Hockey League had a labour stoppage due to negotiations between the league and the players association. Many professional hockey players who could not play in the NHL chose to play in European or North American leagues. The largest number of professional NHL players were in Sweden during the season, including Gothenburg native Daniel Alfredsson, who joined his hometown club for the season. This increased the quality of play and many observers said that Elitserien was the best league in the world during 2004–05.
