(Newark, NJ)  --  Teams that win their division may not be guaranteed a playoff spot if the NBA goes ahead with a proposed format change.  Commissioner Adam Silver says no decision has been made, but the league is leaning toward having the top eight records in each conference qualify for the postseason regardless of division standing.  Division winners are currently guaranteed to be no worse than the fourth seed.  Portland was seeded fourth this past season in the Western Conference after winning the Northwest Division, but the Trail Blazers would have been the sixth seed based on their win-loss record.
