From the way people are respecting Wichita St (who, btw, went to the Final Four last year) picking them to get past the second or third round would be an upset... I think they'll do pretty damn well. (Elite 8, even Final Four)
I picked Harvard, but I don't really even consider that an upset.
I have San Diego St making the Final Four, revenging their close loss to Arizona earlier in the year.
North Dakota St over OU
Creighton over Wisc
otherwise hardly any upsets throughout
