The modern NBA is typically a league built around competitive windows rather than perennial contention. Every team has missed the playoffs at least once in the past decade, except for the Boston Celtics (who last missed in 2013-14).

As the 2025-26 season begins, which teams need to win now, and which would prefer to compete later instead?
