NBA team executives and players’ agents spoke to CNBC in recent weeks about the challenges in resuming play.

NBA teams split the roughly $2 billion per year in national TV money the NBA receives from ESPN and Turner Sports. But clubs also gain revenue from local media deals with Regional Sports Networks.
