I'll be shocked if all the Power 5 play this fall. The protocols required to keep kids safe in a university setting are nearly impossible, let alone when you consider they need to travel across state lines. The University Presidents (and many Governors) will stop most, if not all, football in the next 3-6 months. All it would take is one kid to end up on a ventilator and a campus would explode IMO.
I'd never rule out the SEC though....
