The Worldwide Leader is again looking to stake its claim in the advanced stat revolution, this time in the college basketball realm. Saturday was the unveiling of ESPN’s new College Basketball Power Index (BPI), which ranks all Division I teams 1-344 based on a number of factors that go beyond wins and losses. The two most obvious questions to ask of this new system are: How does the BPI compare to the KenPom and Sagarin ratings that college basketball purists have come to know so well? And is this BPI ranking system any good on its own? These rankings appears to be quite similar to those of the popular KenPom, though there are a couple of unique additions to this system that attempt to make it stand out.
It’s hard to argue with what ESPN is doing here by releasing a brand new metric at the perfect time now that college basketball begins to own much of the sports spotlight for the next month and a half. It will be helpful to read ESPN’s introduction to the index, which gives a chart that points out the features of the BPI compared to RPI, KenPom, and Sagarin, and also describes the benefits of their system that they believe is the most accurate assessment of team rankings. ESPN notes that their numbers include details that are “pretty technical and many people won’t be interested, so we won’t go into detail, but we think they improve how the tool works.” Considering the great technicality with which many purists understand Sagarin and KenPom, it would actually be quite useful to release this ‘technical’ information for comparison’s sake. Regardless, the BPI appears to be quite similar to these accepted ratings. BPI accounts for pace when measuring scoring margin, it awards value to winning close games more than close losses, and it includes detailed strength of schedule numbers.
