notre dame drew 10 million when they played ohio state. they have less than 3 million for every other game on the schedule.
in contrast, michigan has drawn over 4 million in every big ten game, and almost drew 4 million for colorado state. ohio state is the same. even sparty does better rating than notre dame in a lot of weeks.
put notre dame in the big ten and you'll get over 10 million when they play ohio state and michigan, over 6 or 7 when the play penn state or michigan state or even wisconsin, and probably 3 million in every other game.
