I was just refreshing the bracket on ncaa.com, and happened to see that the Semifinal times are no longer TBA. It says the UMD-UND (Not That UND, Except Yes That UND In Any Sport Except Hockey) game is at 5pm and ours is at 8:30 (both are Eastern Time).
Interesting. We figured the UMD game would be later since they can obviously fill the seats in the home state, but maybe they didn't consider that. Or possibly the only 1-seed remaining gets the later game.
