As I said, the plan is looking shaky at the moment. Baseball appears to be working, but those are pros, not college students.
Some CFB teams may be able to "hold it together". But will enough? Take the SEC, imagine Vandy and Mizzou have to shut it down, they lose 7 or 10 players and can't practice. Even if the other 12 have no outbreak, does that shut it all down?
I'd put the chances of completing a ten game season at less than 50% right now.
I don't know what over/under is, maybe 4 games?
