3. Michael Vick
One of the most notorious figures in NFL history, Vick initially rebounded successfully from his time in jail. He helped the Eagles to an NFC East title. In sum, it looked like two years of warming a jail cell hadn’t damaged his abilities. But it wasn’t the case.

The following year, his turnover rate doubled. Just like that, he lost his place as the Eagles’ starting quarterback. From there he went on to become the Steelers’ back-up and floated around the NFL until the end of his career. Nobody wanted him as he sat as a free agent for his final year.
