The interesting thing to track here is if there is some regression in the standings for teams that are highly placed but have a poor goal differential. You can argue that is already happening with Orlando.
Of course, the opposite could be true - some teams might be getting a good goal differential due to luck or other factors not well correlated to overall quality. Atlanta might be an example there.
My guess is that there will be some predictive capacity for these in regard to standings late in the season, but I am not certain of it. Will be fun to watch.
Viewfrom226 does a similar (and more complicated) analysis that he shares on Twitter. It is based on expected goals.
