I don't think the U of N Regents would approve a hockey team for UNL, because it could really hurt the UNO hockey program. The UNO hockey program is the big revenue earner for their sports programs, so I don't see how the Regents would agree to something that would significantly damage UNO.
excellent point...
There are concessions that could be made to help soothe UNO's eventual butthurt over this--promising a two-game home/home series in perpetuity between the programs would be a good bone.
But let's be honest--if UNL wants hockey, they'll have hockey. A lot of the pieces are already complete--we have a conference (B1G) to compete in, day one, we have excellent facilities (Pinnacle Starship), and with hockey, the nice thing is that Women's Hockey is available, which helps remove any real Title XI issues.
This isn't a slam dunk,
but if (enough of) the boosters want it...it will happen. Wouldn't be shocked to see it in place by 2020 or so.
