I have a feeling the new traditiin will be that Neb, Minn, Iowa, and Wisc will all end up playing on Black Friday every year, rotating the opponents every 2 years.
So in 2020-21, both the Neb-Minn and Iowa-Wisc games will end up on a Black Friday double header. That way at least 1 of the games will probably mean something and they can put the best game on ABC and the other game on FS1 or BTN.
Then in 2022-23 it will rotate and it will be Neb-Wisc and Iowa-Minn playing each other.
