Care to count how many teams appear on both lists?
Let me help you: 20. Or 2/3. 2/3 of the teams in the top 30 in defensive efficiency also appear on the list in fewest points per game allowed. 5 of the last 10 are still in the 31-60 ranking in points per game allowed.
I guess maybe points per game allowed isn't a worthless stat after all.
