Sadly, Sophie Cunningham was likely raised by her parents to behave as she does. When she was at Mizzou, there were multiple reports of how her parents would behave badly at games, often encouraging Sophie to go too far, physically, to come out on top. Their No.1 priority was to win, and if it took going outside acceptable sportsmanlike behavior to win, that was okay.
So ... no, if she actually said that I would not be one bit surprised. Sophie Cunningham's parents are trash.
