Knightsbridge - I think you overstate the quality in the P5 a bit:
ACC (15)- Top end: ND, FlSt, LV, Duke, UNC; Mediocrity: Syracuse, Miami, Pittsburgh, GT, VA, NCSt; Bad: BC, WF, VaT, Clem
Big10 (14) - Top end: MD, IA, Ohio; Mediocrity: Rutgers, Northwestern, Minn, Nabraska, Mich; Bad: Mich St, Ill, WI, Ind, Perdue, PSU (?)
Big12 (10) Top end: Baylor, OK; Mediocrity: TX, OkSt, IASt, TCU, WV; Bad: KSSt, KS, TT
Pac12 (12) Top end: Stan, Cal; Mediocrity: OrSt, AZSt, WA; Bad: UCLA, WaSt, USC, CO, OR, AZ, UT
SEC (14) Top end: TN, SC, TxAM, KY; Medicrity: MsSt, LSU; Bad: Missouri, Ole Miss, UGA, AR, Vandy, FL, Auburn, AL.
Looking at the rest of the basketball universe obviously Uconn is a top team and I am not sure there is another in the rest of the conferences, but the 'mediocrity' is probably something like this: Albany, USF, Temple, GWU, Dayton, FGCU, DePaul, Villanova, StJohns, Seton Hall (?), Liberty, JMU, WKy, MTSU, SoMS (?), GB, Princeton, Quin, Marist, WichSt, Chattanooga, ETenn(?), SDSU, ArSt-LR, ArSt (?), Gonz, SD (?) That works out to 26 teams and you could add a few or drop a few out.
