Making sense of the various rankings

[boilerzz]

There is no doubt that Purdue's RPI is ugly. It is currently at 70 according to the NCAA website. However, looking at some other (IMO better) metrics, Purdue doesn't fare so poorly:

Sagarin - 33rd
BPI - 44th
KenPom - 53rd

I'd like to think the continued uproar over the fallacy has caused the committee to continue to devalue it but I just don't know. It would certainly benefit Purdue if they did.
