Gary Bettman has earned respect and kudos from his employers.
The NHL owners know that Bettman has had a huge hand in dramatically increasing the league's revenues since the last lockout.
Bettman has been as responsible as any individual for helping those revenues grow to the $3.3 billion level, an amount that the commissioner reported in late May as the Stanley Cup Finals between the New Jersey Devils and Los Angeles Kings started (source: Sportsnet.ca).
But Bettman's title is not business czar or commissioner of the NHL owners. He is the commissioner of the entire league. He is supposed to represent the interests of the players and the owners. He is supposed to have some kind of vision for the sport beyond business.
Bettman does not meet the needs of the sport other than what he does from a business perspective.
Once a new Collective Bargaining Agreement is signed and the lockout is over, Bettman needs to step down from his position.
If he needs to be pushed out, that would be fine as well.
