Jeff Sagarin keeps a daily updated conference rating for college basketball, both rating simple average (so each team counts equally) and central mean (so the middle teams count for more than the best or worst). Look it up here. In both ratings, for today, the ACC is on top, followed by the Big Ten and the Big East. However, the top 5 conferences (ACC, Big Ten, Big East, Pac-10, Big 12) are all fairly close, with the difference between 1 and 5 less than the difference between 5 and 6 (SEC). If you were grouping sets of conferences by similar rating, it would look something like this: High: ACC, Big Ten, Big East, Pac-10, Big 12 Mid-high: SEC, MWC Mid: Conference USA, MVC, A-10, Horizon Mid-low: WCC, WAC, CAA, MAAC Low: Most everything else Should be in the play-in game every year, because they're worse than the independents: MEAC, SWAC
