I’m not sure your examples are exactly apples to oranges, but I do think they actually support what I am saying. The European countries you are referring to are doing an excellent job of developing a significant portion of the next generation of great basketball players. Young players are (and should be) more likely to play in their home countries than in other countries. But once these players are good enough to play in elite leagues, they can find more money in the NBA and likely to make the jump if they are good enough to star there. Not all players go these days since leagues in Europe are now paying decent salaries, which helps keep players from jumping oversees. But let’s face it, winning the Euroleague championship is not like winning an NBA championship, which is won with many many international players nowadays.
U21 leagues are not comparable to BB since in the U.S. U21 is essentially college, and the best U.S. college players generally don’t play on U21 teams. (The college players in the U.S. from other countries do, though, like Dogus Balbay from Turkey paying at the University of Texas.)
And read my point about player development in local countries again. I was making the argument that making it harder for countries with fewer teams to be able to buy the best talent from the world would actually make it more likely for these countries to develop their own players, hence bolstering their NTs.
Why not give teams from countries with few teams a shot in the BBB? Could you see the Euroleague champions beating the Los Angeles Lakers in a best-of-seven series? The Lakers aren’t just the US NT, they have some top talent from around the world, too (Gasul, Vujacic, Mbenga).
