Stanford pulling away in the second half while UNC is letting OSU back into the game and TN is not closing the door on Pitt. Princeton and FGCU held up well in their losses - the 'other conference' or 'mid major' or whatever you want to call them have some really good teams that play at the same level as the middle of the P5 conferences - the lower end of the at large teams.
I would like the committee to give a couple more at-large bids to those conferences instead of bottom feeding out of the P5 - I know Arkansas won their first round game but they really had no business getting selected with a 6-10 record in their own conference.
I agree with your last sentence 100%. Overall, the SEC performed very poorly in the first 2 rounds. 6th seeded aTm lost to an 11 seed, and 2 seeded Kentucky lost to a 10 seed. LSU lost in the first round, Mississippi State lost in the 2nd round, and aside from Arkansas, no lower seeded team beat a higher seeded team.
Tennessee did not look great in their first round, and really struggled in the 2nd half to eek out a 6-8 point win over 10 seed Pitt. SC is the only "seed" that is performing about how they should be. 30+ point win in the 1st round, 18 point win in the 2nd round. For all the hoopla from SEC fans about how incredible their division is, I'd say the ACC is far outperforming them...
