You want me to do the research for you? Ok I will. Sure.
What fits your criteria? At the time of ranking? How far they went in the postseason? What "type of team" do you think Weber is? That's a low standard. Idk maybe you were really blown away by them today.
You only get a chance to beat "that type of team" once, maybe twice a year.
Last year UND sucked.
The year before they beat the #1 team in the country according to Massey, SDSU.
Can't count that win tho according to your parameters.
The year before that they beat Montana State who finished as the 7th best.
