The breakdown is pretty simple. Expenses for members of the news media are paid by the outlets they work for. Expenses for all the teams and most other campus residents (referees, league officials, game operations people, etc.) are covered by the league.
It costs $550 per day for the reporters covering the N.B.A. restart. That figure includes lodging, three daily meals, transportation to game venues and practice sites and, of course, daily coronavirus testing. Room service meals and food orders from approved off-campus vendors, such as the supplier of my beloved French Dip sandwich, cost extra.
