True that it’s a worse case scenario but most people haven’t been tested yet, few took the early warnings Seriously and it’s in all 50 states already.
The USA is seeing nearly 1,000 new cases a day right now according to www.worldometers.info/Coronavirus/ . It doesn’t seem to be contained and is actually increasing in numbers here. This isn’t China also where the government has far greater control over their people.
I'm not a scientist and I don't pretend to know just how bad this could turn out being but everything I am hearing from people who should know is that the USA population has no idea how really bad this is. To close down all sports, colleges, businesses and to request national guardsmen and the military to "protect" (which I read to mean enforce) quarantine areas, tells me this is very serious and the NBA season is the least of the country's problems currently.
