The facts are inescapable. There will be no covid-19 vaccine until fall 2021, at the earliest. Barring unexpected breakthroughs, there will not be an effective preventive treatment or therapy before then, either.
So, from September 2020 through February 2021, we will not be able to safely fill stadiums with tens of thousands of people each week. A handful of asymptomatic carriers among 60,000 cheering fans could easily spread covid-19 to hundreds, even thousands, of others, causing additional outbreaks of the virus and, quite possibly, more death. Indeed, it was a Champions League soccer match with 40,000 fans in Lombardy, Italy,
that seems to have ignited the explosion of covid-19 cases that shut the country down. That is not a risk the NFL — or the United States — can afford to take.
