Where we are leaning right now is that we would not guarantee a spot for a division winner in part because it's so unlikely to happen, and No. 2 if it does happen it would be potentially confusing to fans. No. 3, you would be displacing a team that did have a top-eight record."
Portland got the No. 4 seed in the Western Conference last season by winning the Northwest Division, but the Trail Blazers would have been seeded sixth by win-loss record.
As a result, the Los Angeles Clippers and San Antonio Spurs, two teams vying for the second seed on the last night of the season, met in the first round of the playoffs.
That sparked new calls to throw out the protection for division winners, and Silver said after the owners' annual summer meeting in Las Vegas that change was coming, though they wanted more time before voting on it.
"So while we're going to continue to discuss it a little bit more -- we need to make a decision before the preseason begins -- I think the greater likelihood is we will not be guaranteeing a spot to a division winner," he said Wednesday.
