8. Michael Vick
Vick was a brilliant quarterback for Atlanta but he should have achieved so much more. However, he lost some of the best years of his career because of his lawbreaking. The former Falcons star was the ringleader of a dogfighting operation and served time in jail. Obviously, this wasn’t conducive to a successful NFL career. But to his credit, Vick returned to the league after his release.
He also performed to a high standard for the Philadelphia Eagles. But he never reached his full potential because of his antics outside of football (via The Guardian). Vick’s influence on the sport shouldn’t be understated. His ability as a rushing quarterback revolutionized many coaching strategies. Unfortunately, he let himself down and this cost him the opportunity to become an all-time great.
