The Colts’ defense has been just as good as Luck in the fourth quarter. Quarterback Andrew Luck is usually the first person to come to mind when talking about the Indianapolis Colts’ fourth-quarter success. Luck does deserve credit. They’ve only allowed seven points in the final quarter this season. San Francisco and Seattle, two Super Bowl contending teams, are on the list of shutout victims. “It’s impressive,” Luck said. Indianapolis defense has been so impressive that they haven’t allowed any points since Oakland’s Terrelle Pryor found Denarius Moore on a 5-yard touchdown pass with 11:09 left in the game in Week 1.
