It's been 6 years since the Big Ten Network first started broadcasting and I feel that is a long enough sample size to look at the long term results. Whether the evidence in connected or not there is no doubting that since the 2007 season that the B1G has fallen well below the SEC, PAC-12, and ACC conferences.
Is it a coincidence? Or has the limited market of the BTN affected the national perception of the conference? To me, almost all BTN televised games have the feeling of it being amateur hour. Whereas I've never had that feeling watching a couple of middling ACC teams go at it.
It just seems like those old school bruiser games like Wisconsin vs Minnesota have been marginalized. They used to be top tier Big Ten matchups but are now relegated to filler between nacho dip commercials
Don't get me wrong, the proof is in the pudding. The B1G still has to beat top opponents. But I can't help to think that the BTN's constant coverage and commercialization has hurt more than it has helped as opposed to schools that always have ESPN airing their games.
