Cedevita, Cibona and Zadar pushing for a “closed” ABA Liga?

Cedevita, Cibona and Zadar have an agreement with the Croatian Federation to play in ABA Liga but only if the league is open to new team every year and it is not a closed league as the NBA.
The three Croatian teams which compete in ABA Liga, Cedevita, Cibona and Zadar, want a closed Adriatic League.
The teams would love ABA Liga to sign multi-year agreements with some selected teams to keep the level of the competition always very high.
