I said my piece about this back in March. But yeah, needless to say, it’s difficult to imagine how a sport with as much close physical contact as football will escape mass infections among players unless the teams *and* all support staff are kept in quarantine throughout the season. If you placed the entire players’ union in isolation, that’s around 2,500 people to start. Figure another 1,000 or more collectively among refs, trainers, doctors, locker-room personnel, security, and so on, just to make the games run.
And their families too, of course, unless you expect the players to isolate themselves separately for six months from the start of training camp until the Super Bowl. Thousands of people, all walled off from their loved ones, and not a single person can break the rules and sneak out for some social activity without placing the entire season at risk.
Imagine if they actually did it. Seventeen weeks of the regular season followed by several weeks of the playoffs with not a single infection throughout the league. And then, the week before the Super Bowl, one of the conference champions has an outbreak.
