About a week or a week-and-a-half ago, I looked at the Summit League website to see how the conference tournament host is determined. At that time, Denver was already announced as the host, but Oral Roberts was leading the standings, and the season wasn't even over. So, based on that, the tournament is at a pre-determined location.
I also meant to look into the conference schedule to see how league games are organized. If they are truly Friday to Sunday, I think UND Athletics Department would take issue with that, with hockey games on Friday and Saturday nights. I really liked the Thursday night/Saturday mid-day schedule. Maybe UND will get to choose it's game nights/days. I would think Denver would prefer to not play on Friday, also being a hockey school.
