New schedule brings "back-to-back-to-back" situation that creates new types of rest days. It seems crazy at first, but you'll get it when you go through below examples. More insane events from the condensed season: the new schedule features a 9-IN-12! (nine games in 12 days) stint for the Hawks; Cleveland has a franchise record 9 game home-stand; Toronto will play 19-IN-31 in January, etc. You can extend those by downloading NBA schedule in Excel and build your own analysis.

Take X, as the day with a game played and take O, as the off day.
