10. Alonzo Spellman, Chicago Bears, Dallas Cowboys & Detroit Lions:
Monster defensive end Spellman had been diagnosed with bipolar disorder but refused to take medication and coped with the symptoms by using illegal drugs and alcohol.
His real trouble with the law came after his career was over. He created a manic scene on a plane in 2002 when he said the flight was headed to crash. Spellman then threatened fellow passengers and the crew of the plane. The incident was so bad that he forced an emergency landing. Spellman was released to his brother’s custody but damaged property at his house. He was committed to a mental hospital. Police later arrested him for the scene and he spent 18 months in prison.
Spellman was arrested again on 10 counts of eluding police in a 2008 car chase. Spellman was arrested yet again for multiple warrants and in 2015.
