Starting this season, a new promotion and demotion system has been implemented! 5th ranked teams are now actively involved in the offseason and will join in the fight for survival in the playouts, having to battle it out with 7th ranked teams of the opposing conference. Also, as announced, 6th ranked teams will face each other with the home court advantage going to the team with the better regular season record. The additional promotion spots will be filled with the best ranked teams from lower division leagues, similar to how bot promotion works. The change will surely bring some extra excitement and better flow across the divisions.
