I could see it happening. It's a sport that we can field both men's and women's teams for (no Title IX problems), we have a hockey conference we'd automatically belong to (B1G starting hockey conference ) this year. I'd say it's a matter of when, and not if.
I don't think the University of Nebraska Regents would approve for UNL. UNO hockey is the main revenue earner for their sports prorams. The NU regents wouldn't want to hurt UNO athletics by adding UNL hockey.
