Yeah, I didn't have numbers at the ready but I have seen where NIU has better TV ratings than many of the schools that are often mentioned. This post backs up what I've seen elsewhere. I think current numbers still reflect this.
Also something to consider, is that often NIU pulls in better ratings despite being relegated to a lesser ESPN channel, for example, NIU pulls in higher ratings on ESPN2 than some AAC schools pull in on ESPN. Given that these schools will be in the Big 12 and have access to better TV slots only helps their case. I think NIU is one of the candidates with the most "growth potential" which is being listed as a factor being considered.
I just think that people here blindly dismiss them because, I don't know, they're in the MAC? MAC...AAC...same difference. If looked at objectively, NIU is one of the better available candidates. Luckily, nobody here is making the decision.
