Most of us would agree that the Immaculate Reception was Franco Harris' defining play. James Harrison's 100 yard Interception return was his defining play. Antwaan Randle El's pass in Super Bowl XL was his defining play. Andy Russell's 90 yard lumbering interception return. Roethlisberger has had a couple of defining plays. Which Polamalu play do you pick - Jumping over the line to make a stop; the Int return in AFCCG; or the INT where he picks the ball inches off the ground? And there are some players whose defining play produced a negative outcome, specifically one player I refuse to name. Sadly, it is hard to come up with defining plays for the offensive line and to an extent the defensive line. Also, some players possible defining play might instead be a defining image or picture. Who remembers Jack Lambert shoving Cliff Harris in the Super Bowl after Roy Gerela missed a kick and Harris tapped him on the helmet? Did Lambert's actions change the outcome of that game? I listed some of the more iconic defining plays, but what players do you remember as having defining plays? Is Hines Ward hit on Keith Rivers his defining play or is it a catch in Super Bowl XL?
