This paper will look in depth at the power structure of expansion, as the NHL is considering expanding into two new markets in the coming years, Las Vegas, Nevada and Quebec City, Quebec. It will look at the current NHL expansion proposals and examine the roles of a number of stakeholders. Expansion in a major league sport involves many individuals and groups including: Board of Governors for the NHL, private developers, arena owners, NHL Commissioner, other NHL Executives, current NHL owners, coach and players as well as governments of the localities proposed in expansion. All these groups and individuals have some role in expansion, this paper will show the most of the power lies within the NHL as an organization, and includes the Commissioner, other Executives, and the Board of Governors. The localities of Las Vegas and Quebec City have some power as government units, but within these communities most of the power lies with the developer(s) who are looking to bring the NHL to these two cities.
