Why is basketball...

Trying to play the finals and finish everything before the season even starts?
Do they have some other schedule coming up?
What is wrong with this schedule?
And the South Korean coach is a foreigner.
It seems like more than half of the Japanese players are naturalized citizens.
Just how bad are the players in their domestic league
that more than half of the national team are naturalized players?
I only watch the game against Japan briefly
and watch the rest through highlights,
but it's truly strange.
