The NBA has already discussed an in-season tournament if play can resume this summer, which Silver said requires more dialogue, but also added would be implemented at some point. One NBA executive said this is the opportunity to explore the concept for at least for one year, in what could be spectator-free arenas. The executive, who spoke to CNBC on condition of autonomy as the individual is not authorized to talk about the matter, suggested opening a new season via a tournament on Christmas.
