James told reporters he would "disagree" with changing the current postseason structure because the NBA has had "dominant conferences throughout time," via Basketball Insiders' Spencer Davies:
NBA Commissioner Adam Silver told reporters during All-Star Weekend the league will look into playoff formatting because it "would like to have a format where your two best teams are ultimately going to meet in the Finals."
Silver did note one of the main challenges is travel, as the league was "concerned about teams crisscrossing the country in the first round, for example."
The NBA has used its current 16-team playoff format, with eight teams from each conference, since 1984. Teams are currently seeded one through eight based on their record in the regular season, with the higher-seeded team having home-court advantage.
