Incidentally, white elephants are a major reason why baseball is out of the Olympics. There doesn't seem to be another major sport that needs a baseball/softball sized stadium, so the baseball facilities will be white elephants in any country that doesn't already play baseball.
Other sports are not having an issue.
Soccer and tennis fields aren't issues, since all countries play them.
Hockey is ice, which can be used for just plain skating.
Basketball arenas can be build in a way to be transformable for other uses.
Agreed. But the dimensions of baseball stadia are such that they are ill-suited for other uses.
