All right, James Harrison didn't really take ballet classes—as far as we know—but it sure looked like he did when he was tiptoeing down the sideline during Super Bowl XLIII.
The Arizona Cardinals were a Cinderella story heading into the title tilt. Kurt Warner had revived his career, leading his team against the storied and vaunted Pittsburgh Steelers.
It was supposed to be a bloodbath. The Cardinals, who had never played in a Super Bowl, barely made the playoffs, and they were going up against the league's top defense. The Steelers were favored by seven, but the Cardinals were not going to be pushovers.
Warner had driven the Cardinals into the red zone just before halftime when he made a critical mistake. He passed the ball to the goal line—to James Harrison.
The big linebacker rumbled 100 yards down the sideline to the other end zone, improbably staying in bounds while avoiding would-be tacklers. The play was a huge swing in the game—the Cardinals, in essence, went from taking a 14-10 lead to falling behind 17-7 at halftime. Pittsburgh ended up winning the game 27-23.
