Missouri went down first in the afternoon. Then Duke was knocked out in the evening. Not the other way around as you described. Pac12 only had two teams in the big dance. So they did okay with 50% advancing to the next round. 要說顏面盡失, it is that only two teams barely squeezed in, not the result of the first round. BTW, officially that was the second round after they expanded into 68 teams.
