Jimmy, Jimmy, Jimmy... I love you bro, but you're arguing a point that just isn't on solid ground. An argument could be made that the cold virus doesn't primarily spread through handshakes or fist bumps, but it still spread via those avenues of contact. I can't imagine the players didn't touch their faces, cough into their gloves, or rub their nose before throwing the ball. A game with a ball that everybody handles will always be a great avenue for any communicable disease, because everybody touches the rock. I've played basketball in the past, and I've seen my entire team go down from a cold virus after a game.
I think it's better to argue that athletes and all workers should be allowed with relative normality, because there may never be a cure for coronavirus. There may never be a medical solution, so there's no point in prolonging the inevitable viral infection, especially during the summer. Do I like this argument? No. I don't even know if it makes sense. But I haven't a better one for you. In all fairness, the players shouldn't be giving handshakes to each other after a game. That is just a common sense method for limiting exposure.
