In The Game has come up with a great analysis of how the Euroleague A licenses will be taken away and handed out using a three-year-ranking system.
The performance of teams in European competitions during a three year period will be used. Each club will get 2 points for a win and 1 point for a loss from the Regular Season onwards. 2 bonus points are allocated for reaching the last 16, 2 bonus points are allocated for reaching the last 8, 1 bonus point is allocated for reaching the last 4, 1 bonus point is allocated for reaching the Final.
The Club Ranking consists of the sum of the club coefficients from the last three years. If two or more teams have the same Club Ranking, the tie will be resolved by the total number of wins during the three year period. Should a tie persist, the final standings in the Euroleague and if necessary Eurocup from the previous season will be used to break the tie.
