Just throwing some numbers together it looks like the committee did a good job for the seed groups. By using committee rank, NET, RPI, KenPom and bracket matrix almost all of the seed groups don't change but the order within the groups vary slightly. Virginia should be the #1 overall slightly over Duke. Iowa State should be the third #6 instead of the second #6.
Auburn and K. St. should trade seeds, so should Marquette and Buffalo and Maryland and Wofford. St Mary's is #11, should be a #9, Ole Miss is #8, should be #10.
Clemson, Texas and TCU might have gotten shafted as their numbers look better than Temple, Belmont and Minnesota, and for sure should have been in before Arizona St., Ohio St. and St. John's. I would guess those three and N. Carolina St. will be the #1 seeds in NIT.
