1. What does essential have to do with anything? Kids on campus are at least as much at risk as fans at a game.
2. It looks to me that you, and others, are using the pandemic to dictate what others can and cannot do based on your value system. But, I will play along.
School can be postponed just as easily as a football game can be. Learning can be done remotely just as football can be played without fans. If the school goes under, professors need to find some other way to support themselves. If a football program collapses, coaches need to find some other way to support themselves. Really, these are the exact same thing.
A football season can be played during the second semester. It is not vitally important that we have college football games in 4 months. The Fall semester cannot be moved to the 2nd semester. Yes, they can have an online semester and I have said they will but going to college from home is not what these kids signed up for and it would financially cripple the schools so having the kids on campus is far more important, essential, whatever than playing a football game that can be played at a later date.
I am sorry but if you want football in the fall, the only way is
a) a medical breakthrough (the new Remdesivir trial looks promising)
b) no fans
If there isn't a medical breakthrough, there is no way fans are going to be allowed to attend games in the fall other than the parents of the players potentially.
