What expression is used to describe the nationality choice made by players?

The expression "It's an irrevocable choice" accurately reflects the nature of the nationality decision that players make in the realm of international basketball. Once a player chooses a nationality to represent, that decision is definitive and cannot be undone. This irrevocability is crucial in the context of FIBA rules, which are designed to create clarity and stability within international competitions.

Players cannot easily switch nationalities back and forth as this could lead to complications such as player eligibility and team integrity in international tournaments. The commitment to represent a particular nation carries significant implications, not only for the player's career but also for the national teams involved. This aspect underscores the seriousness and permanence associated with choosing a nationality in basketball, distinguishing it from other choices that might allow for more flexibility or change.
