57 finalists? how many of them will get the final spot in the olympics?
I think it's not necessary that Lebron or KD will play in the Olympics, even with the younger players, USA still is the heavy favorites to bag the gold medal.
Of course they still want to let an NBA All-star play because they can still put on a show even though its the Olympics. As long as they are an available player which is hand selected by the USA coach, they will be able to play and of course they are also launching try outs for the team but NBA players are heavily favored to join because of their experience.
