White House Discusses Plan To Reopen With Sports Leagues

I see no reason the NFL won't be playing. It'll be to empty stadiums with piped in noise, but testing before each game will be an easy thing to do by the fall. The risk to people under 40 is nearly nil as well. The key will be having protocols in place if someone does test positive in order to quarantine them and keep them from endangering demographics that are at risk. That shouldn't be hard to manage.
The under 40 quote, is a bit short. Under 40 folks can catch the virus just as easy, but their full recovery is much higher, So football players like the Brees’ and Brady’s, are at a slightly higher risk of having a bad result from contracting the virus. But how do you mitigate the potential for the asymptomatic players? They can pass it on, without showing any signs. Every player would need to be fully tested, every week at least! I do not think there is a sure way, to ensure there would not be a sudden outbreak in any given team sport! Tennis and golf should be able to resume more quickly.
