This week, the always-excellent Scott Van Pelt unleashed a rather cathartic rant about the essential uselessness of the Ratings Percentage Index, or RPI. The points Van Pelt made are the ones that must always be made about the RPI: 1. The RPI is older than the compact disc, and roughly as technologically advanced. 2. The RPI's methodology (who you beat plus who your opponents beat plus who your opponents' opponents beat) is really dumb. There are countless rankings systems that provide a much more realistic methodology, including the numbers generated and maintained by Ken Pomeroy and Jeff Sagarin, Ken Massey, the big brains that built the LRMC and, most recently, the ESPN Analytics Group's new Basketball Power Index, which is, after a mere week of existence, already five or six times better at evaluating bubble teams than is the RPI.
