I guess being one of the worst teams in the league at giving up points is good in your eyes.
We could argue about fg % allowed or points per shot, but in a system in which the shot clock rarely goes down to 15 or below in our offense and opponents usually cannot resist running with us, how can you even think of points allowed as a benchmark? It just does not make sense at all. If the shot volume is about 15% above average, it would be insanely good defense to hold an opponent even at league average.
