I don't buy it. First, a field hospital in Madison in November would cause more problems than they would solve so I don't see that being a solution.
Totally plausible that the program closes up and waits until 2021. I got the impression that Wisconsin, Minnesota, Michigan, etc. reluctantly signed on to play the season this fall after seeing all the conferences that take athletics seriously continue playing and tried getting back to normal. Selfishly, I hope these schools suffer in enrollments and recruiting in the near future as they severely botched the past several months. Hypocritical at the very, very least.
