The first phase is a regular season, in which the competing teams are drawn into three groups, each containing eight teams. Each team plays every other team in its group at home and away, resulting in 14 games for each team in the first stage. The top 5 teams in each group and the best sixth-placed team advance to the next round. The complete list of tiebreakers is provided in the lead-in to the Regular Season results.
The surviving teams are divided into four groups of four teams each, and again a round-robin system is adopted resulting in 6 games each, with the top 2 teams advancing to the quarterfinals. Tiebreakers are identical to those used in the Regular Season.
In the quarterfinals, the top placed teams from each Top 16 group play second placed teams from a different group in a best-of-three playoff series, with the winners of those series advancing to the Final Four.
The culminating stage of the Euroleague in which the four remaining teams play a semifinal match and the winners of those advance to the final. The losers play in a third-place playoff. The team which is victorious in the Final will be Euroleague champion.
The draw was held February 5 at 13:00 CET (1200 UTC) in Barcelona, in accordance with Euroleague rules.
The teams were placed into four pools, as follows:
Level 1: The three group winners, plus the top-ranked second-place team
CSKA, TAU, Panathinaikos, Dynamo
Level 2: The remaining second-place teams, plus the top two third-place teams
Winterthur FCB, Maccabi, Olympiacos, Benetton
Level 3: The remaining third-place team, plus the three fourth-place teams
Joventut, Efes, Pau-Orthez, Unicaja
Level 4: The fifth-place teams, plus the top ranked sixth-place team
Lottomatica, Aris, Prokom, Partizan
Each Top 16 group included one team from each pool. The draw was conducted under the following restrictions:
No more than two teams from the same Regular Season group can be placed in the same Top 16 group.
No more than two teams from the same country can be placed in the same Top 16 group.
If there is a conflict between these two restrictions, (1) will receive priority.
Another draw was held to determine the order of fixtures. In cases of two teams from the same city in the Top 16 (CSKA and Dynamo, Panathinaikos and Olympiacos, Winterthur FCB and Joventut) they were scheduled so that every week only one team would be at home.
Key to colors
Top two places in each group advance to quarterfinals
Each quarterfinal was a best-of-three series between a first-place team in the Top 16 and a second-place team from a different group, with the first-place team receiving home advantage. Quarterfinals were played on April 3 and 5, 2007, with third games to be played April 12 if necessary.
