I will say, what made it still feel more like a big rivalry, even while UM was dominating, was that for the second portion of that run, OSU was consistently the higher ranked team, only to have Michigan rise up and beat them. Didn't UM knock them out of the national championship game like 4 times in a decade (93, 95, 96, 03)? So while UM dominated the series, the fact that they were doing it for a period while being frequently the lower ranked team almost made it seem MORE like a rivalry. While Ohio State has dominated the recent years, they've done it as the favorite almost exclusively, so it doesn't really have the same feel.
