Someone who knows nothing about basketball has a question

Is the current national team coach doing a good job?
Or are the opposing players in the Asian Games just weak?
Last year, while Korea was playing "Code State" (?), the shooting and fast breaks were so fun to watch that I was cheering for them.
But with this current coach, it's been a bit boring and we keep losing, so I wasn't a fan.
But then suddenly, we started winning by huge margins.
