Jamal Lewis
Most NFL franchises cut ties with players after they receive a serious criminal conviction and jail time. But the Ravens made the unusual choice to keep Lewis on their roster after his drug-dealing scandal. But that’s because he was one of the most exciting players of his generation and they didn’t want anybody to have him.

Remember, he had a ridiculous 2,000-yard season including a record-breaking 295-yard game. The running back won the 2003 Offensive Player of the Year award for his stunning production. He went to jail for four months in 2005 but returned to play four more seasons in the NFL (via Pro Football History).
