Silver said owners reviewed data over about 30 years, while also considering the need for traditional rivalries born out of having divisions and conferences.
''When we presented all the data to the teams, what becomes clear is that there is no obvious solution,'' Silver said.
''It's not to say that we don't think there should be a change. I think this is one of these issues that is going to require a fair amount of discussion and study, not just directly among the owners in the big room, with committees as well.''
Another change could come quickly. He said there were discussions about extending the 2015-16 season by a week, which he said could reduce the number of back-to-backs to an all-time low average of 16 per team, with an average of just one four-in-five-nights stretch per team.
The playoffs and draft lottery apparently will stay the same.
Definitely a good move to cut down on back-to-backs. I'm also fine with the league holding off on changes to the Playoff format or lottery, as I feel the problems with both are somewhat exaggerated.
