For what it's worth, Harvard announced they will be
open Fall 2020.
“If our community has not developed sufficient levels of immunity through recovery from the disease or vaccination, and if safe and effective antiviral therapy is not available, we will likely need adequate supplies of personal protective equipment, reliable and convenient viral testing, robust contact tracing procedures, and facilities for quarantine and isolation,” he said.
“Should we not be able to resume a fully on-campus experience, our efforts will not end with a shift to remote teaching and learning,” he wrote.
“In its 384-year history, Harvard has overcome many adversities, drawing on the courage and determination of its community,” he added. “This extraordinary time calls on us to build on that history, working together in ways we never have before.”
I'm about 90% sure we'll have CFB come fall. Fans in seats right away, maybe not. But that can hurt.
In a snapshot from 2013, Michigan ticket sales were nearly 50% of the revenue. So I suppose we could say with ballpark that every game with no fans is bye bye to 2-4% revenue?
