Brad Berry won 2020. I think he avoided a possible embarrassing defeat in the tournament. UND wasn't playing particularly great down the stretch in 2020 going 3-2-1 against WMU, St Cloud, and Omaha....Western being the only one of those three being above .500, but still only good enough to finish 4th in the NCHC. I think the offense punched above their weight a lot of the year, and in the tournament when things get more physical and the ice seems to shrink a bit, I don't think there was a guarantee they'd have the horses to make a deep run. Their defense was great and would have likely kept them in games, but I don't think there was a lot of guaranteed success ahead for UND.
Remember, the following year being the #2 overall seed we only managed to beat AIC (Div II) before losing in the following round and also failing to make the Frozen Four.
