That is the one that that media outlets without an official poll of their own will use. The best one in my mind is D1 Baseball, without question, as it's put together by the best writers in the business who are all college baseball junkies. None of the polls "matter" when it comes to the postseason, like in football. The official NCAA RPI is the biggest factor in determining seeding and hosting, and that will begin being released and updated daily in April. For now, the RPI numbers on Warren Nolan and Boyd's World are the best indicators of where the NCAA numbers would be.
