Shlenker met
Roy Hofheinz, the owner of the
Houston Astros of
Major League Baseball and the
Astrodome. Shlenker began promoting non-sporting events held at the Astrodome. Shlenker became a part-owner of the
Houston Rockets of the
National Basketball Association (NBA) in 1982. In May 1985, he bought the NBA's
Denver Nuggets for $20 million. He reached an agreement with the city of Denver to renovate the
McNichols Arena. In June 1987, the
Major Indoor Soccer League granted a conditional franchise to Shlenker, to begin play in the 1988–89 season. The team, tentatively named the "Denver Desperados", attracted deposits for 400 season tickets within four months, short of the required 5,000; the franchise was revoked in November 1987. In September 1988, Shlenker purchased the
Colorado / Denver Rangers of the
International Hockey League. He declared the team bankrupt in June 1989. Shlenker sold the Nuggets in November 1989 for $65 million. The year before, Shlenker's plans to remove the
Mississippi River Museum on
Mud Island to make space for bars and restaurants fell through thanks to intervention of the
West Tennessee Historical Society, the Mud Island Foundation, and then-Mayor of Memphis,
Richard Hackett. ==Personal life==
