I'm personally the type of individual that really has to restrain themselves from not punching your run of the mill cretin in the throat at Publix when they pull their mask down as soon as they get by the dude at the front door or walk around with their greasy nose completely exposed the whole time....
....but this sideline stuff in college and the NFL and even the NBA is purely useless optics and theater. If any of these athletes/coaches are going to be infected by each other then it'll come during the 10000 other times they're around each other and maskless.
If we're going to be concerned about anything specific to these college teams then it should just be that they're making all the right decisions when on campus around the germ addled hoi polloi.
