Tank teams do it in other countries, I don't see an advantage, in that respect, to doing this in a smaller country.
You don't want to see advantage. In small country You can tank 10 seasons and never be relegated bellow 2nd league ;-)
In big country You will be relegated to 5th division ;-) And in 5th division weekly overall incomes are = ~20k ;-)
And trust me, even with higher TV contracts and merchandises in big country still it's better to tank in small country.
In big country if You make decision to tank, it means You must be relegated. In small country You can tank even without relegation.
And one more important thing - in small country You can win many matches without effort and it means You fans are happier and You ticket incomes are higher. And plese remember that tickets incomes are more important than TV and merchandise.
And quick example. You joined to BB 5 seasons after me. And now You have stronger team than me. And it isn't effect of better managment, strategy or tactic, etc. It's effect of playing in small country.
