I use Defensive On/Off....and occasionally something like the RAPTOR or LEBRON or RPM metrics.
I'm not a fan of using on/off. It leaves so much context out. I greatly prefer RPM which takes more context (opponents and teammates) into account. In both cases you need a lot of sample (like ideally multiple years) to get a good value. I agree that box score stats are less useful for defensive measurement (and I'm not a fan of defensive rating) but I do look at BPM as a good baseline as it does not require the volume of sample that on/off related stats do.
Also, I feel like their was a basic misunderstanding between you and Bama on this. Maybe I am confused, but I thought Bama, when referencing last year, was referring to last season, but you are providing stats for this season. You can easily make the argument that KP was a better defender than Collins last season. He was a quality rim protector while Collins was miscast as a center that year and struggled protecting the rim.
This season there is not any question. KP was struggling all year with his mobility and Collins greatly benefitted having Capella behind him.
