re: This face shield is going to have players huffing CO2, the mouthpiece should have

When do they put them on? Must they wear them the entire game even if they’re not playing? Is there enough room for them to social distance on the side line? What about halftime in the locker room? Will they keep their helmets on? Or put masks on and social distance? Is there enough room for that in the locker room? Especially visiting team locker rooms which are considerably smaller. If not then what’s the point of the stupid face shield? fogging up and possibly costing the game!
