The problem is when Buero is the coach of Spanish NT and he has 4-5 players of his team play in NT too.
You can believe these players are the best or not; in the second case, the only explaination is the boost in money coming from having NT players and this is very bad if you look it outside.
I would like to think every NT managers are doing the best efforts for their owns NT teams but there could be some "bad apples" as said in a post above.
