My bad. I got that from a box score on this site that showed no goals scored in OT. What the box score didn’t show was the 3x3 OT. I forgot that In 2019 they were still playing a 5x5 OT first then 3x3 (I still prefer that format).
Whether you count a 3x3 OT win as a win (2023) or tie (2019) in your W/L record, you still get the same number of conference points. When is the last time UND swept all the conference points in Denver?
