The defending Greek Basket League champions, Olympiacos, finished first in the regular season, and faced their arch-rivals Panathinaikos, in the finals of the playoffs, having home-court advantage. Despite the home court advantage, Panathinaikos won the series 3-0, by performing a "clean sweep", after defeating Olympiacos twice at their home-court. The 3rd game was disrupted by Olympiacos fans throwing flash-grenades at Panathinaikos' bench, when the score was 72-76 with 01:27 left to go in the game.

The match officials decided to stop the game, and have the stadium cleared of all fans. 75 minutes went by, and 100+ Olympiacos fans had still not vacated the stadium, so the game and the series was officially called off. A technicality win of 0-20 was granted to Panathinaikos, despite there still being 01:27 left on the game clock.

The events of the 3rd game of the series, happened after the owner of Panathinaikos, Dimitrios Giannakopoulos, and three other men, entered into the referee locker room at the home arena of Panathinaikos, OAKA, during halftime of the 2nd game of the series. Giannakopoulos reportedly told the refs that they would not leave the arena, if they did not change how they were calling the game, with Panathinaikos behind in the score at halftime.[1][2] Giannkopoulos was later sanctioned by the Greek sports prosecutor for these actions.[3] Giannakopoulos was then banned from entering into any arenas in Greece by the Greek Committee of Sportsmanship, for a period of 6 months, however, he was placed on 3 years of probation and given a suspended sentence.[4] He was however, suspended from entering into the arenas at his own team's games, for a period of 3 months time.[5]
