"A lot of talk about Nigeria getting several players to play for them at once, none born in nigeria."
And?
For our NBA players who've had children born in the USA, should those kids not be allowed to play for Australia?
Should Irving not have been allowed to play for the USA?
Maybe if your parents were so poor they didn't have a pot to piss in, they were likely to be murdered in ethnic and tribal violence, and you were most likely to die as an infant, they too would have taken any opportunity to get into the USA, or indeed anywhere slightly less hellish.
"Japan has edwards born in arizona, watanabe born in hawaii."
Watanabe (Hogland) has a Japanese mother, and has NEVER played BASKETBALL for the USA.
A lot of the lists floating around are COMPOSITES, and include players from different stages.
(Other lists are just plain fucked, ascribing "Country" based on their current professional team.)
