The 2026-27 NBA season opens October 20 with roster continuity and star availability shaping early playoff positioning across both conferences. Defending champion New York returns most of its title core after a dominant prior postseason, while San Antonio and Oklahoma City carry forward strong regular-season records and depth from last year. Eastern shifts from LeBron James joining Philadelphia and Giannis Antetokounmpo moving to Miami have elevated those clubs' outlooks, though health concerns for veterans remain key variables. Western depth and young cores in teams like Houston and Denver create tighter races for the lower seeds, with preseason form and official injury reports providing the first updates on rotation stability.
