This is life in 2020-21, it will be dangerous. Even besides the jobs defined as essential this spring, there's not an extremely safe way to be a bartender, server, teacher, student, and the list goes on.
I think sports in general have laid out pretty good plans, though colleges have it the hardest due to the vast number of athletes and varying budgets. With pro sports, I think the athletes and staff are probably just as safe playing under their protocols than they would be living their lives back home. I'd like to think colleges can pull that off, but it's gonna be bumpy.
A lot of things are just going to have to move forward. A bunch of people like to cry "Lawsuits!" and yeah, that's a thing but you'll need a good lawyer and even then, get in line because there's like 2.5 million people who got sick and can probably argue some government or company put them at risk. If you watched "Dark Waters" you saw how difficult that slam dunk case was to pull off, and how many years it took. And the guilty company still thrives.
