Gary Bettman has been the commissioner of the National Hockey League since 1993.
When he was hired, he had the mandate from NHL ownership to make the league more viable in the United States in terms of its television contract and to bring labor peace. The league did not want to deal with any labor stoppages.
Bettman has been commissioner during two lengthy work stoppages in his tenure. While television deals have gotten much better since 1993, the league still does not approach the NBA or Major League Baseball in what those organizations bring home. The NFL dwarfs what those two leagues bring home, so the NHL gets just a drop in the bucket compared to football.
While it's natural for the front man of any of the major sports organization to take grief from its fans, there's nothing in the other sports that compares to the embarrassment of Bettman handing out the Stanley Cup to the league's champion.
Unpopularity is not a mistake in itself, but it is indicative that hockey fans recognize his shortcomings.
Here are 10 of his biggest fails as commissioner.
