If you're a Steelers fan too young to remember the Immaculate Reception, you're probably at least old enough to remember the Steelers' 2005 playoff upset of the Colts.
Even though the stadium and the quarterback are different, the Steelers return to Indianapolis today for the first time since that game.
Just like the Immaculate Reception got the Steelers over the hump in terms of winning playoff games, that upset of the Colts catapulted the Steelers over the hurdle to the Super Bowl. After so many losses in the AFC title game, no way were the Steelers losing in Denver a week after stunning the mighty Colts.
With Ben Roethlisberger saving Jerome Bettis from infamy with his tackle of Nick Harper, and the "thank God" field goal miss by the Colts kicker, the 2005 playoff game packed enough unlikely events to be almost as memorable as the Immaculate Reception.
It was the franchise's most pivotal win in the post-Steel -Curtain Era. Since then, anything short of a Lombardi Trophy is considered a failure. For Steelers fans of this generation, it was our Immaculate Reception.
