It’s hard to imagine a bigger momentum shift in a football game than this one. The fact that it happened on football’s grandest stage – at Super Bowl 43 in Tampa on the first day of February in 2009 – made it even more impactful. Eighteen seconds remained in the first half, and the Cardinals trailed the Steelers 10-7 but had a 1st-and-goal at the Pittsburgh 2. From the shotgun, quarterback Kurt Warner took the snap and – as the Steelers showed blitz – threw a pass to the goal line towards receiver Anquan Boldin. James Harrison, a Steelers’ Pro Bowl linebacker, jumped in front and picked it off. With several Steelers blocking for him, he ran down the right sideline, breaking a tackle shy of midfield. He then patiently hopped over a Steeler while following another block and – quickly losing steam and with the clock nearing zero – he avoided a tackle before being hit by Cardinals receiver Steve Breaston a few yards from the goal line, and Harrison fell forward for a touchdown. The 100-yard interception return gave the Steelers a 17-7 lead – they’d eventually win, 27-23 – and the return became the longest play in Super Bowl history (since eclipsed by Jacoby Jones 108-yard kickoff return in Super Bowl XVII).
