You won’t find a lot of sympathy here for the Big Ten hockey conference. College hockey is a sport whose rivalries were defined in ways different from football and basketball.
Putting together a “super conference” featuring Wisconsin, Minnesota, Michigan hockey and Michigan State looks like gold on paper. In practice it is less exciting. It is almost guaranteed that at least one of those teams will be left out of the NCAA tournament. Programs that have combined for over 5,000 victories and 23 national titles don’t need to subject themselves to that.
From a scheduling point of view it does create some interesting possibilities though.
