<P> From 1984 until 2008, the Utah Jazz hosted a tournament known as the Rocky Mountain Revue . Launched as a community outreach campaign to encourage interest in the Jazz in the summer of 1984 under the direction of Jazz public relations staffers David Allred and Kim Turner, initially the league operated as a three - week, pro-am league in July with alumni players from Utah, BYU, Weber State and Utah State . In 1990, after sending a team to the California Summer League the previous summer, Scott Layden, then the Jazz's director of basketball operations, invited the Portland Trail Blazers, Phoenix Suns, and Sacramento Kings to join the league and moved to an all - NBA format . Over the course of the next 20 years, as few as four teams (1990) and as many as 16 teams (1998), participated, including the first International entry, Burghy Roma . The league did not play games during the 1999 strike - shortened season . In 2008, the NBA Development League had a D - League Ambassadors team . The Rocky Mountain Revue also showcased the Iranian national team . </P> <P> Games were hosted at Westminster College (Salt Lake City), East High School (Salt Lake City), Delta Center and the Revue's final home, Salt Lake Community College .
