The Capitanes — or at least the seed of the idea that became the Capitanes — was born in Los Angeles in April 2016 during Kobe Bryant’s final game with the Lakers before he retired from the N.B.A. Moisés Cosío and Rodrigo Trujillo, film producers and longtime friends, had landed tickets and watched Bryant clutter the box score with 60 points. Their conversation turned to the basketball scene back home in Mexico City, where several teams in the country’s top league, known as Liga Nacional de Baloncesto Profesional, or L.N.B.P., had been flops in recent years. But Cosío and Trujillo sensed there was untapped potential for the sport to become more popular there.
