I think it's more just that basketball is more popular in the Balkans than in the rest of Europe. You see more basketball courts there, anyway.
and we are shit. I don't think it's height. Serbia has ruled European basketball for some time.
It's kinda like baseball where the every european championship has been won by either the Dutch or Italians
It's not easy being a scrawny man in such a country. You're not exactly any woman's first pick (speaking from personal experience). I reckon I'd be an average human in most other (non-African) countries or a giant in Asian ones :)
For example Bojan Bogdanović is born in Bosnia but if you ask him je Will tell you he is Croatian.
