The NBA and the National Basketball Players Association are scheduled to host a conference call for all players Friday to field and address such concerns, sources told ESPN's Ramona Shelburne. 

Most teams are in the process of re-opening their practice facilities while implementing social distancing protocol.

Dallas Mavericks owner Mark Cuban questioned the wisdom of the NBA's return.

Cuban, speaking to ESPN Radio's Freddie & Fitzsimmons, framed the issues in terms of who players, coaches and trainers trust with their lives. 

"Seriously. If you're a player, who do you trust with your life?" Cuban said. "If you're a coach or a trainer or, anybody for that matter, that's essential personnel for getting something back together, do you trust the hotel that we're going to stay at to keep everything safe -- the technology they're using, the protocols they're using? 

"Who do you trust with your life?" Cuban repeated. "That's a big question to ask somebody, but we all make decisions like that every day. Do you stay in? Do you go out? What do you do? Where do you go for your groceries? All these things, how do you do it?" 

Oddsmakers continue to offer futures on which team will win the NBA Championship.
