10. Michael Vick
Vick was one of the most exciting quarterbacks in the NFL in 2007. He was the first black QB to become the first overall pick and redefined the position with the Falcons. But then a major scandal erupted when federal law enforcement arrested him.

The signal-caller was also the ringleader of a dog-fighting ring. Horrendous details emerged about his cruelty toward animals and he went to jail. Meanwhile, the NFL suspended him. He rehabilitated his career after his release and joined the Eagles (via Marca).
