Flash Points: Steelers' defining moment

What key event significantly changed the fortunes of the Steelers -- for better or worse? Give us your take and we'll give you our definitive moment on May 18.

When you've won more Super Bowls (six) than any team in NFL history, there are a lot of great moments that can define a franchise. But which moment best defines the rich history of the Pittsburgh Steelers?

Was it the "Immaculate Reception" when Hall of Fame running back Franco Harris took an improbable catch the distance to beat the Oakland Raiders late in a 1972 playoff game? What about Pittsburgh's Super Bowl X victory over the Dallas Cowboys, which capped its first of two back-to-back title runs in the 1970s?

Pittsburgh's 1974 draft class to land linebacker Jack Lambert, center Mike Webster and receivers Lynn Swann and John Stallworth -- all Hall of Famers -- is often viewed as the best ever and led to four championships. Was that the defining moment in Steelers history? Or was it coach Chuck Noll's hiring in 1969?

There are tons of great moments for the Steelers. But using our SportsNation poll, we ask our community to pick the most defining moment in Pittsburgh history.
