Glades, I know you went to Pitt so I'd like you to elaborate on that program. They routinely only got about 30,000-35,000 fans because, imo, Pittsburgh loves their pro sports [have to compete with Steeler fans], yet they won a national championship as an independent. Isn't that the model we might ought to think about when we are thinking about low fan attendance? I know Sherrell brought in some good recruits but it wasn't like they came to Pittsburgh to play in front of thousands of fans. Even when Marino had a nice run there and no national championships, but national contenders, their fan attendance was lacking. Did you follow the Pitt program or did you spend all of your time in "Cathy"?
Also, I think your thesis question is a tough one to answer but, I think the answer has nothing to do with fan attendance, rather politics.
I can point to several examples, but we needn't look past last year. OSU leap frogged over the horn frogs of TCU, and Baylor. TCU was #3 and was arguably the best team in College football. Yet, they were excluded from the Playoff system as well as Baylor. Both schools averaged over 30% less than 70,000 and could have had a decent chance at being a National Champ. TCU averaged 45,000. Baylor averaged 46,000. As with most national championships, it's political. We have seen it time and again.
As an aside, TCU and Baylor both had brand new stadiums. Baylor's is gorgeous. True enough, they both have capacity crowds as the planners modeled Minnesota and made small stadiums that can fill up and be noisy. Interesting enough, Baylor's stadium has among the best locker rooms in the country, huge video boards, #15th biggest video boards in college football

But at the end of the day, I think Northwestern nailed this one. I mean, if I'm a player, I would love such a wonderful practice facility that is so convenient and awesome where I spend 90% of my football time, as opposed to a wonderful football stadium where I only spend 18 hours a year in. So, I don't think players make their final decisions to come play at a college because of how many fans watch them. Maybe it's on the list somewhere after about the #10th reason, but I also don't think fan attendance has the slightest thing to do with National Championships. Glades Thesis.....DENIED!
