Back in May, before the procedures for the NBA restart (and most other sports) had been sorted out, Alicia examined how the leagues that were including families in the set-up seemed to be having more success at securing player buy-in. That finding is fairly obvious — people like being around their loved ones, and family can provide a source of comfort and stability in an otherwise unnatural situation, like a three-month-long quarantine bubble.
Ultimately the NBA settled on allowing family members onto the campus site after the first round of the playoffs to limit the total number of occupants.
