8. I Forgot To Read The Playbook
Billy Joe Hobert neglected to read the playbook,” said a Bills fan. “Maybe we start there? There are some crazy historic quarterback mistakes on this list but most of them are in-game mistakes. Those are somewhat forgivable but Hobert committed one of the worst offenses in NFL history. Many regard the QB position as the most difficult in the world of sport because they must remember so many plays.

However, Hobert simply didn’t bother. In 1997, the Bills played the Patriots and Todd Collins suffered a shoulder injury. Then, Marc Levy told Hobert it was his time to shine. Hobert hadn’t expected to play and so he didn’t spend any time preparing for the game. Needless to say, it was a disaster and the Bills didn’t feel forgiving afterward. They waived him for his negligence.
