9. Barret Robbins, Oakland Raiders:
Robbins suffers from bipolar depression and went missing the day before the Oakland Raiders’ appearance in Super Bowl XXXVII. He supposedly went on an alcohol-fueled rampage in Mexico. His wife later revealed he thought the team had won the Super Bowl and he was celebrating their victory. Robbins did not even recognize his then-coach Bill Callahan when he was brought back to the team.
Robbins was then kicked out of football for taking steroids during the BALCO scandal. Months later he assaulted policemen in Miami Beach and was shot three times. He was charged with attempted murder. He pleaded guilty to five charges and was in jail and/or rehabilitation for the better part of a decade. Robbins was later caught with crack cocaine and sentenced to five years in prison for violating his probation. Finally, in 2016 he allegedly punched a woman and her daughter in Florida, earning him two felony battery charges. Robbins was sent to a mental hospital.
