8. The Fail Mary (2012)
This was a disaster from beginning to end because the officials simply were not good enough. The NFL referees went on strike so the league brought in a posse of unproven replacements. However, there was a stark difference in quality and it became clear that the new referees weren’t up to the task. It all came to a head when the Seahawks played the Packers in the NFC Divisional Round (via NBC Sports).

The Packers led 12-7 with eight seconds left in the game but it wasn’t over. Then, Russell Wilson desperately flung a Hail Mary toward the endzone. Golden Tate jumped up to catch it but so did Packers safety M.D. Jennings. In fact, anybody watching saw that Jennings intercepted the pass. However, the referees didn’t agree and awarded Tate the touchdown. But at least it ended the referee strike, right?
