I'm awful late to this one but if UNL decided to start men's hockey, I believe it would be a huge draw. This state likes hockey with UNO's attendance and 3 USHL teams that all draw well.
I am a UNO hockey fan because UNL doesnt have a team. If UNL were to announce, i'd switch immediately as I believe alot of people would. Cue the jokes, but UNL is all this state has and if you put a "N" on the jersey, people will follow it. Throw in some early success and watch out. We certainly dont have basketball to keep us entertained in the winter.
I believe initially they would play to packed houses that would rival any of the big boys in hockey. However there better be some success or it would drop off (see UNL basketball). While the new arena being built downtown didnt initially have ice included, I have heard rumors that that part could be added if need be. I personally would LOVE Husker hockey but I fear its a pipe dream.
