Not sure where AZSioux's brackets came from, unless they are his own, but USCHO currently has both ND and Wisco in the 16 teams.
You may be right on the games the Sioux have to win. They are very close in turning the power points vs MSU, Cornell, Mass-Lowell, Harvard, Colgate and UNH back in their favor, but they need to improve their record vs. TUC's (currently 6-8-2). Fortunately, Bemidji is a TUC currently, so the Sioux could improve their record to 8-8-2 if they win both (and we hope Bemidji remains a TUC). Denver and Wisco again afford the Sioux the opportunity to improve their record vs TUC's. Also depends on what the above teams do against remaining TUC's on their schedules, but all could be turned in favor of the Sioux.
