Parity in football? The CFP was the usual suspects with 2 new rich kids.
College football - Miami was a 10 seed and upset Texas A&M and a very large upset against reigning national champion Ohio State. Indiana went 3-9 including 1-8 in conference in 2023.
I consider that parity.
Whereas the NCAA tournament saw no large first round upsets, which is relatively uncommon. And ultimately the final four are top teams.
I almost stated 3 no 1s. But it was lovely watching dook choke it away.
The one common denominator in all of this is that the $EC doesn’t seem to be as dominant - largely due the playing field being leveled with teams being able to legally pay players for play.
