The answer is easy when you consider the below description of NBA players today:
pri·ma don·na
ˌprēmə ˈdänə/
noun
noun: primadonna
a very temperamental person with an inflated view of their own talent or importance.
synonyms: ego, self-important person, his nibs, temperamental person, princess, diva, pooh-bah; informal drama queen
"a city council filled with prima donnas"
The only thing they got wrong above in describing the word & NBA together perfectly as one was using the word "city" where they should have stated "a sports league filled with prima donnas"
