No P5 conference wants to be the first to cancel the season, so the Big 10 is working with the Pac 12 to announce that both will cancelling their seasons. I would guess that they are also talking to the ACC, SEC and Big 12 and trying to find out what they are going to do.
To me the holdouts for cancelling seem to be the SEC and Big 12. I can see the SEC, but the Big 12 has to be looking at the number of cases in Texas and just saying "this idea of playing this fall, is just not going to happen."
Hate to do this but I'm now joining the SEC chants. Please have mercy.
