Those ideas have been shared openly on the league’s weekly general manager’s call, sources say, with the latest iteration on Thursday including optimism that a solution would be found and a continued focus on building an environment that’s on par with the Walt Disney World campus when it comes to the extensive precautions taken. Sources say the Cavs, Pistons and Hawks have been among the most vocal organizations and several teams (including the Timberwolves) are expressing interest in possibly serving as the hosts. Sources say Las Vegas and Houston were among the cities mentioned by league officials as possible locations on the Thursday call.
