I think I have figured a potential reason for one of the bigger issues with NET. It seems very resistance to change. It is hard to move up or down in the rankings. I think this is part of the issue with efficiency metrics. There are thousands of possessions in a year. The denominator is so large, it is hard to change these much late in the year. Compare that to wins, where you can change your winning percentage pretty dramatically with a few wins in a row or a few losses. Teams are just not changing in the NET
