Again, if you study the RPI ratings versus the selection committee placements over the last few years, there is little even halfway close correlation, which should tell you all you need to know about what tools are really used. I remember back around 2003 being confused about the big discrepancy between RPI and BEast team placements, and it took awhile before the light went off for me and I realized that the committee was not just a bunch of double-dealing cheats. Each of the members can use whatever tools they want in forming their vote on a team, but I'm guessing that Sagarin plays a much bigger role for them than any squints at the RPI tables.
Much of Charlie's placements seem just off so far this year and I'm not sure why he's giving VG mumbly responses about RPI anymore when he knows a lot better than that. Especially so when OK State had a relatively poor RPI rating of #28 last night before getting blown out by WVU, a team with much better RPI. Not sure what will happen when the Realtime RPI is updated later today.
That said, I will confess that RPI along with the Nolan system seems in my view to be rating OK State better than the usually more respected services. OK State is a prime example of a mediocre B12 team that tried to milk the SOS system with a schedule that started off with 11 home OOC games, and they played no away games until their 3rd B12 game on Jan. 8. That should not be allowed to happen. They'll probably still be able to take their results to an undeservedly good seed in the tourney, but they've really done squat all season. Their 4 wins for their 4-5 record against the Sagarin top 25 have come against teams rated 17, 21, 22, 23, and all were home games.
