The NBA has had characters like Dennis Rodman and Metta World Peace. The NFL and MLB shared Deion Sanders, also known as "Prime Time." But for a sport that prides itself on its clean-cut nature, NASCAR has its share of controversial figures—from some of the sport's most prominent legends to current superstars.
