UND didn't have "attendance problems" at that point in their history, correct? So, sure, not proof, but since we sold out games nearly every season during that run, it seems like a pretty solid assumption. 75" TVs (referring, in general to large TVs) are much more common now, man. The comforts of home are higher now than 10 years ago. Just another overall discussion point as to why less people come to games. However, UND fans come to see teams win games. Back in 2009, we were on an unprecedented run of success. People came to watch them. I don't know how much more I can say about that. We sold out the barn to watch Michigan Tech back when they were garbage year in and year out.
I don't recall seeing a game with over 4,000 empty seats for a UND hockey game ever, including last year. That is over 25% of the arena.
*sigh* alright, man. This is just gonna keep going in circles. I'll continue to wholly disagree that Notre Dame would have filled that arena last night. And, even if they would have, that's still not an indication that we should leave the NCHC.
Overall... win more games and the fans will stay, in general.
