I am guessing part of the problem with the ACC not getting the reimbursement from media rights they would like has to do with the collapse of FSU football the past 15-years, the collapse of Virginia Tech football, and which left Clemson as the only power football program in the ACC. There is a relative lack of fan interest in football with the ACC teams not V-Tech, FSU, and Clemson as compared with fan interest in the Big Ten that are not tOSU, and Michigan. FSU is coming back, but has itself to blame for its recent demise.
In 1980, I recall my upstairs neighbor in Tallahassee asking about my interest in college football because I came from Iowa. I didn't at the time realize that outside of Iowa, people in general believed fan interest in Big Ten football and Iowa football would be high. I was from Iowa, not Michigan or Ohio. He was very interested in FSU football which was on the rise.
Coming into 1980, Iowa had 19-consecutive nonwinning seasons, and yet he must have known about the culture of football fandom in the Midwest, generally, to have prompted that question. My interest in Iowa football was very high, but not rewarded, and I was not optimistic about Iowa football. But, then in 1980, the Hawkeyes won the Big Ten title (or tied) and were in the Rose Bowl. I don't get away enough.
FSU to the Big Ten is a remote possibility if west coast teams to the Big Ten are a reality. FSU is closer than the west coast.
