It is interesting (at least to me) to look at the road records of teams right now. The Celtics are the best on the road but there are only a few team over 0.500 at all, with a few surprises:
BOS +10 (games over 0.500 on road)
BKN +6
PHI +4
NYK +4
SAC +2
DEN +1
Not sure what this means but at a minimum, I think it correlates pretty well with what the best teams are. With BKN, it mostly represents the team with Durant. NYK is an outlier but they have played pretty well in stretches. They are 11-13 at home though. DEN is clearly a good team and SAC has been good.
MEM (not on the list) is 20-3 at home, 11-12 on the road. Big difference and maybe an indication that there is some weakness there. I don't know. One or the other probably won't sustain. Either at home will get worse or on the road will get better. Of the 2, it seems keeping that home pace will be harder to maintain as opposed improving on the road.
