The science says that the virus is transmitted via droplets. And I'm not sure whether or not you know how close to the stands our sideline is, and what goes on behind that space between the sidelines and the stands. There is a constant scurry of activity from folks interacting with players, coaches, and officials on the sidelines. The science shows that talking can generate droplets that linger in the air for some time. Add in the coughing, sneezing, and yelling that take place in the stands, and the fact that the Delta variant is more contagious. We have no idea yet whether players can catch this Delta variant from the stands. But why run the risk when you don't have to?
