I'm not sure why this even matters. Past the age of 15, does anyone even idolize professional athletes (with a few well-earned exceptions)? The shark move is to make sure your kids grow up knowing larger-than-life professional athletes (and actors, actresses, politicians, etc.) are all just people, and shouldn't be idolized, or at least copied.
They are incredible athletes playing a game for our entertainment, and they make a lot of money doing it They don't need to be anything more than that, and yet people set unrealistic expectations for the NFL as a whole. Enjoy it for what it is. Don't put them on a pedestal. They are human, just like everyone else. And some of them are just downright scum trash. And yet they are still good at football, and deserve to be paid what the market demands for their services in their field, as long as they aren't convicted felons. Just like everyone else in America.
