The argument about finances makes no sense to me. I would expect the revenue to be better with a Spring season with full capacity in the stadiums than it would be in the Fall with 1/3 capacity (if that) stadiums. The TV coverage for Spring college football would be incredible. Postponing the season makes more financial sense than stubbornly sticking to some kind of traditional Fall schedule.
Take a guarantee of less money in the Fall vs a chance of no money in the Spring. No one knows if it will be better
