Adrian Peterson
Peterson is one of the NFL’s greatest running backs ever. But brilliance on the playing field doesn’t mean that somebody is a good person in real life. The former Vikings star’s parenting methods attracted negative attention in 2014. This came after he lashed his son with a switch as a punishment.
The seedy star narrowly avoided prison time but the NFL suspended him for the remainder of the season. He also attended community service because it was a terrible thing to do. Peterson had a tough upbringing and saw nothing wrong with his actions at the time (via NFL.com).
