The situation isn't playing out in the Big-12, SEC, or ACC, because neither of those conferences had the overstretched ego to take it upon themselves to become the dictator of P5 college football and declare that there would be no season.
The ACC already manipulated their schedule just a week ago to make sure that Clemson and Notre Dame are getting an open week this weekend before playing in the title game. Don't want COVID killing the golden geese, after all.
