They weren't booing. They were saying JuJu. Thousands of gold towels helicoptered in the air across Lucas Oil Stadium as hoards of black-and-gold clad fans screamed after each big play the Pittsburgh Steelers' rookie sensation made. "JU-JU!" They shouted after Smith-Schuster hauled in a 7-yard strike from quarterback Ben Roesthlisberger for a second-half Steelers touchdown. Steeler Nation was even louder after kicker Chris Boswell knocked home the game-winning 33-yard field goal to lift the Pittsburgh Steelers to their fourth straight win, a 20-17 victory over the Indianapolis Colts. "The fans were awesome," said Steelers quarterback Ben Roesthlisberger. "So many Terrible Towels. It's always fun to see them represent in away cities." If Colts fans were booing their team for dropping to 3-7 and faltering for the fourth time in five tries, their jeers were drowned out by the robust Steelers crowd. In fact, Colts fans in attendance must have been shaking their heads in disbelief as the nearly sold-out stadium rocked time and time again after momentous Steelers' plays.
