Correct you are UteBacker. As Oregon was the preseason favorite to win the North, and USC the preseason favorite to win the South, they would be the marquee league game this year — the 2019 CCG notwithstanding.
The BigTen claimed the Nebraska pairings were incidental, but it’s not like they’d openly admit it either. That just goes to show what might happen to programs who don’t play the part of “team player”. As unfortunate as it was to have to postpone their season, a league needs to remain unified — for long-term purposes. But if you’re a selfish program, who’s only in it for yourself, you might as well try forming a new league with the tdS.
