From what I've seen of both teams:
If UND gets any kind of momentum, whether that be the first goal, or strong play, watch out, as I think the tUMD goalies are shaky. This ain't Stalock you have (although just as much luck, they have less skill).
But, tUMD somehow is finding a way more often than not this season. Can't explain it. Confidence? Luck? Enough skill to eke out a few they shouldn't eke out? No clue.
I'd say split if I think about it, but gut feeling is UND sweep, if only to muddle the WCHA more, which is tradition.
