I have written something on the main page outlining some of this, I didn't go into enormous detail on others as it wasn't really the time for it (it was long enough already!) but you are right to highlight those 3. Each of them are within the classical venture capitalist from the US approach. We have already seen what the last recession (much shallower than I believe this one will be) did to Hicks and Gilette. Them went from funding Liverpool quite expansively, to very quickly looking raise funds from the club to cover other losses.
All of them will say the right things, but a significant initial shock can cause people to start panicking. Each of them have investments in the US sports they want to protect. FSG have been very aggressive in their approach with Boston Red Socks on player trading, at times being happy to put in short term pain for long term gain.
As for Trump, what he's doing looks an unbelievable risk. Even before this outbreak he was polling behind Biden and Sanders. He will be further behind now. A massive recession and he's toast. Desperate people take big risks.
My hunch would be, that re-opening will spike the deaths and cases further. To levels higher than even China. Panic will again set in and the markets will continue to crumble.
If I were a fan of any of the above 3, for differing reasons I'd be very worried.
