I think you underestimate the reach of lots of these schools in terms of national trends. Walk ddown the street in most big cities and you’ll find on Saturday a Michigan bar, an Ohio State bar, Notre Dame bars…you look at UConn even, most fans have never set foot in a classroom in Storrs. In fact most have never set foot on campus anywhere but Gampel. Guys from Ohio who went to Yale and then to Wall Street are the same way. Ohio State fans. To say nothing of the people who just selected one of those national brands to root for. If you look at the current round of changes, it isn’t about performance or markets or any of that it is about brands. USC and UCLA and Texas are all basically also fans for the past decade. But they have brand recognition.
In some ways, though we are returning to the way things were in the 1960s through 1980s. There were big national teams, Ohio State, Michigan, Texas Norte Dame Southern Cal, Alabama, Penn State etc. Then there was another level of sort of good regional powers, Syracuse, Pitt, West Virginia, BC, are examples in the East, the MAC was the midwestern version, who occasionally played national programs but seldom won, and even occasionally were among the best in the country, as Syracuse was in the mid-60s, or Pitt was under Majors, but those “ dynasties” seldom lasted long. Then there were regional teams like the Yankee Conference, Colgate, Rutgers, Temple Lehigh, etc. we Most had decent followings played other regional teams.
