This should be less of an issue this year (and in the future) league wide.
The NBA is starting the season 2 weeks earlier than normal (usually starts on last Tuesday in Oct., which would be 10/31 this year, but is instead starting on 10/17) and is also eliminating some pre-season games.
They've worked to reduce back-to-backs and four-games-in-five-nights over the last few years. Take a look at these trends:
Back-to-backs, league avg:
2015 - 19.3
2016 - 17.8
2017 - 16.3
4-games-in-5-nights, league total:
2015 - 70
2016 - 27
2017 - 20
It will be interesting to see how low they can reduce the back-to-back number this year, and they most likely will be completely eliminating all 4-games-5-nights stretches.
Also the C's being one of the top teams in the league might help here as well, as they'll have more national TV games.
Per Lowe, the league is trying to make sure teams in national TV games are both coming off a rest day (though this may just mean the TV game is the 1st game of a back-to-back instead of the 2nd).
