Why cherry pick when we can look at all of them? From the past 5 available years in your source (too lazy to go back farther), including Neb Rutgers and Maryland.
And sorted in order of TV ratings, with Mid Majors bolded.
It's interesting that games against Mid Majors have never been the lowest rating. It's always uninspiring BCS conf opponents playing each other.
Even the 10 worst ratings (excluding the NA) are dominated by major conf. matchups: 0.4 (Oklahoma St.), 0.83 (Iowa St.), 0.93 (Texas Tech), 1.2 (Kansas), 1.42 (Kansas St.), 1.59 (Ball St.), 1.71 (Miss St.), 1.72 (ECU), 1.89 (UCF), 2.00 (NC St.)
