There was much controversy last year concerning the playoff seeding. Many teams did not like the fact that the division leaders were seeded 1,2, and 3 regardless of their record. Next year, that will change. According to Hoopsworld:
Starting in the upcoming season, the top four seeds -- the three division winners and the second-place team with the best record -- will be seeded according to their win-loss total, guaranteeing that the top two teams in each conference can't meet until the conference finals, the league announced Wednesday.
The NBA had given the top three seeds to division winners regardless of record, meaning a second-place team could not do better than the No. 4 seed, even if it had a better record than a division champion.
