Adrian Peterson
Peterson was one of the Vikings’ greatest-ever players but he tarnished his legacy in 2014. The former MVP battered his son with a ‘switch’ as he used an old-school punishment. He didn’t realize that most people don’t accept this type of behavior in the modern era. But Peterson’s justification was that his own father did it to him.

This should have taught him that it’s not a very nice thing to do. His son received slashes to his legs, back, and genitals. In the end, Minnesota only deactivated him for a single game. Remember, he was a very good player and children don’t matter. It felt like that was their message because they didn’t punish him, but he still missed an entire NFL season due to the act (via The Guardian).
