Was this the "worst" loss ever in the big 12?
I mean, the 2 seed losing to 11 seed at home has probably never happened, but you then have to throw in #5 ranking 
possibly. thankfullly it really cost us nothing. maybe a #1/2 seed. but we're still playing for a #3/2 seed.
No doubt, it was a bad loss.
Biggest loss is the 1 seed, or being the 2 seed in the same region as the 4th 1 seed.
If we stay as a 2 seed, which is likely with a win or two in KC, then we'll be in UK or 'Cuse's bracket, but still likely play in OKC in the first weekend.
