NBA commissioner Adam Silver's plans for a potential European venture face a potential problem in Paris, where an existing team, Paris Basketball, has exclusive rights to suitable arenas. The team already has owners and a budget that might be below what Silver envisions. However, there are other potential partners for the NBA in Europe with unlimited resources, such as Real Madrid and Barca of Barcelona. The NBA's main partner in establishing a new league in Europe, FIBA, wants participating teams to play in their own national leagues and qualify for competition in the new league based on merit or performance in their own countries.
