Ohio State didn't beat Wisconsin twice. Wisconsin isn't very good right now--and hasn't been as good as it is supposed to be since 2019. That's why Chryst was fired.
The Minnesota loss last year is instructive. The Badgers were good enough to be in contention for the Big Ten West, then Minnesota thoroughly outplayed them to keep them out of the CCG, showing that Wisconsin was merely an above-the-mean Big Ten West team. As noted above, it's not just losing, it's how you lose. Minnesota was clearly the better team. It's ok that this could happen in isolation, but it's not ok that it's a pattern. In the Alvarez Era, Wisconsin has become accustomed to being a contender, not merely above-the-mean. It's been too long, and this year showed things getting worse, not better.
This may have been a terrible move. We will see. Maybe this will make Badgers feel like Cornhuskers, wandering in the wilderness.
But what it shows is that the Wisconsin Athletic Department is not the Iowa Athletic Department, and doesn't want to be. And while I wouldn't have fired Chryst based on the limited information I have, I appreciate that the Athletic Director has no interest in sustained mediocrity.
