No two teams have faced each other, both in the top ten, more times than Michigan - OSU. This is the 24th meeting. It's also 4 of the last 5. The 70's were more concentrated than that, but this is still a really impressive stretch we've got the short end of.
I wonder what those numbers would be when adjusted by End Of Season rankings. Those are more accurate IMO. How many Top 10 teams drop out by end of the year? Bo won so few Bowl Games, I doubt UM was still Top 10 at end of the year. And back then teams legit played their bowl games unlike now where kids decide not to play. After what happened to Butt, that is understandable. A nice 16 team playoff would help change that.
