I don't think football has to be an all or nothing if the decision is made to keep moving forward. If a stadium holds 100k, drop it to 35k and spread them out. We did that voluntarily last year -- it can work.
Imagine how smart it would have looked now if that stadium renovation had ripped out all the bleachers, reduced capacity, and went luxury instead.
Here's where I think the problem will be with that - How do you justify protecting your fans by limiting (or eliminating) attendance, yet you don't provide protection for the players?
I've never been one to advocate paying players (I am pro compensation for likeness, etc) or unionizing, but in a case like Covid it makes things much more clear cut. The NBA/NFL/MLB is going to play because the players are going to agree to the risk. They are going to agree to take on the risk because the upside is millions of dollars and they also have control of the situation and how they will be protected.
College athletes have no control and have little to gain in this. The media is going to start saying the exact same thing a lot more as the season gets closer. And if you haven't noticed, CFB players have realized they've got some pull. All it is going to take is a few team leaders from a major program to publicly question whether they should be playing this year. That will open the floodgates.
