If one thing has been made abundantly clear during this pandemic, it's that the coronavirus is nondiscriminatory. While it certainly doesn't affect everyone the same way, places where mass testing is available shows anyone can get infected, even if they're ultimately asymptomatic.
So far, two NFL head coaches have had the virus. New Orleans coach Sean Payton contracted the virus in March, briefly experiencing flu-like symptoms, followed by several days of fatigue. More recently, as the league began its first week of in-person work this offseason, Philadelphia's Doug Pederson tested positive. Fortunately for him, he fell under the asymptomatic category.
