As I type this, I am currently watching the Sunday Night Football game between the Green Bay Packers and the Pittsburgh Steelers.
The Packers' quarterback, Brett Hundley #7, is chewing gum as he plays, something that I don't believe is possible when wearing a mouthguard. (It does not appear at all that he is wearing a mouthguard.) I thought that by the rules, they are required safety gear just as much as a helmet is?
