Corrected entry: In an NBA finals series, the higher ranked team has home court advantage. The first 2 games are played at one arena, then the next 2 are played at the other team's arena. Game 6 was played in Boston meaning they were the lower ranked team. Yet the dramatic game 7 was also played in Boston. This is impossible because at least one of the final 2 games would have to be played in Utah, regardless of who was ranked higher.
Correction: Just to confirm, the film has it correct. At the time of filming, NBA Finals followed the 2-3-2 format. The '94 Finals went 7 games and both game 6 and game 7 were played in Houston. It's only the rounds leading up to the finals that followed the 2-2-1-1-1 format. For example, the '96 Conference Finals went 7 games and game 6 was in Utah and Game 7 was in Seattle.
Correction: In the 2013-14 season the NBA changed the NBA Finals format from 2-3-2 that was being used during the filming of this movie to the now being used 2-2-1-1-1 format.
Correction: That used to be the NBA Finals format until 1985. Now the first two games are played at the higher ranked team's arena, the next three games are played at the lower ranked team's arena, and the final two games are played at the higher ranked team's arena. This format is only used in the finals because of the longer travel from the east to west coast.
