The National Hockey League missed an entire season due to the infamous 2004-05 lockout, which resulted from conflicts over a salary cap. NHL owners said 75% of team revenues was going to players’ salaries — something the players’ union disputed. The union eventually conceded to a salary cap of $49 million per team, but the owners insisted on $42.5 million. NHL commissioner Gary Bettman canceled the season on Feb. 16. It marked the first time one of the big four sports leagues in the U.S. lost a season’s worth of games to labor issues. Read “Hockey’s Season On Ice.”
