Prior to 2005, NBA division champions were seeded higher than the other teams in their conference, regardless of their record. Prior to 2004, when the NBA was aligned into two conferences with two divisions each, the division champions were guaranteed the top two seeds. This meant that top two teams in a conference (by record) would be seeded either first and second (if they were in opposite divisions) or first and third (if they were in the same division). Because of the NBA playoffs' preset matchups in the second round, this meant that the top two teams in a conference could never meet until the conference finals, assuming they both made it to that round.
