The second competition system modification will expand the Turkish Airlines Euroleague Top 16 by dividing the best teams coming from the regular season into two Groups (E and F) rather than the previous four. With this change, the Top 16 Draw will be eliminated. The two new Top 16 groups would be composed based on regular-season standings, as follows:
Group E: A1, B2, C3, D4, C1, D2, A3, B4
Group F: B1, C2, D3, A4, D1, A2, B3, C4
The effect of the change to two groups means that the Turkish Airlines Euroleague Top 16 will expand from the current six games to a total of 14 per group.
Besides these competition system modifications, another important change to be implemented in the 2012-13 season will make the official Turkish Airlines Euroleague game days Thursday and Friday of each playing week.
This change to Friday games has already been tested during the current season on two occasions, in regular season Game 1 between Gescrap BB and Olympiacos and in Game 3 between Panathinaikos and Zalgiris, with positive results in both arena attendance and TV audiences.
