11. San Francisco 49ers vs. Baltimore Ravens (2012)
The 49ers had an undefeated Super Bowl record before 2012. However, the Ravens brought this to an end in soul-destroying style. Baltimore took a 28-6 lead before a power surge gave the Niners’ a brief hiatus. Then San Francisco came firing back and dragged themselves back into the game.

Joe Flacco had the game of his life but it appeared as though San Francisco had the momentum. However, outstanding Ravens’ in-game coaching kept them alive and they won. It was a tough break for the 49ers but they gave themselves too much work to do (via New York Times).
