Peyton Manning
Manning was one of the greatest quarterbacks to step onto a football field. He won two Super Bowls and was a five-time NFL MVP during his time with the Colts. Most people may find it surprising that he’s on this list because he avoided controversy throughout his career. But they don’t know about one disgusting incident during his college days (via Bleacher Report).

In 1996, Manning allegedly sexually assaulted a young woman when he brandished his penis in front of her. This came after the female doctor examined his foot for a stress fracture. According to the woman, he forced his body parts in her face and she later attended a rape crisis center. However, Manning denied these claims and the University of Tennessee stayed silent.
