If you were wondering what the reason was the Big10 decided not to play football, it was for political reasons. The decision was made at the president/chancellor level. They were asked by national Democrats to cancel the season with the idea being they could blame the cancellation of football on Trump and anger football fans in those states into voting for Biden. Fortunately, not all the other Power 5 conferences went along with this scheme.
The decision has produced some desperate results. In Pennsylvania for example, high school football is back, the NFL's Eagles and Steelers are almost back, Temple and Pitt is back playing college football -- basically everyone in the state is back playing except for Penn St. How weird is that?
Here is the new Biden ad running in Big 10 states where Biden directly blames Trump for no football.
