Best Realistic Scenario on How to Actually Have a 2020 NFL Season - Washington Post

The next most important step would be having all team personnel agree to quarantining in their own home cities.

With that said, IF that happens, I'm not sure you need the mandatory 14-day quarantine every time teams travel assuming they're quarantined while in their home cities.

It's doable, as Dr. Fauci said a couple weeks ago. But it requires a ton of cooperation and sacrifice above and beyond the normal from all those involved in the league.
