First revision:
[Validity] Any nations with no "No Sports" policy.
[Description] After Brancaland just naturalized six @@DEMONYM@@ players, and subsequently mopped the floor with @@NAME@@ at the Football World Cup, a group of so-called 'sports experts' has invaded your office just as you are about to take a bite ouf of a particularly outlandish sandwich.
1. "Our loss against Brancaland was a national embarrassment! With Brancaland allowing athletes to take their citizenship left right and centre, we have to react to allow @@NAME@@ to remain competitive!" yells Coach @@RANDOMNAME@@ after blowing his whistle three times to get your attention. "Change the laws that we can naturalize anybody that could help us win everything!"
[Result] coaches spend more time trying to see who is @@DEMONYM@@ today than coaching.
2. "Give me that!" screams your Minister for Sports, trying to pull the whistle from the coach's lips. "We can't just give out citizenships nilly-willy for any mercenary athlete coming to our lands. Make a law that after five years they can apply for @@DEMONYM@@ citizenship and then are eligible to perform for @@NAME@@."
[Result] athletes carry calendars onto the pitch to see when they are allowed to switch nations.
3. "Hogwash," exclaims a nonagenarian that claims to have been part of the first Olympic Games even though they happened several hundred years ago. "If you want to perform for @@NAME@@ you have to be born in @@NAME@@, your parents have to be born in @@NAME@@ and your grandparents have to be born in @@NAME@@. No, we don't need noone from no other places!"
[Result] signing up for high school tryouts requires a full genealogical survey of the last three generations.
