Masks help limit spread of airborne aerosols. They do not prevent it. They do not protect you as wearer. Even N95 respirators are only rated to 0.3 microns. Corona is ~0.1 um.
You don’t touch anyone at the game?????? I high five everybody around me after a big play. You never had a drunk fan fall into you or worse puke on you???? Do you scream at the top of your lungs on third down or just sit quietly shaking your key? Do you ever need to go to the bathroom at halftime and stand shoulder to shoulder at the trough???
I want to watch the games as much as anyone but remember these are GAMES. Our health and safety is a little more important.
