Their most impressive victory came in Week 3 of the season when they went to take on San Francisco 49ers.
They beat the 49ers at their own game. Indianapolis was aggressive on defense, limiting the 49ers to 254 yards of total offense. San Francisco picked up 91 yards on its opening drive.
Offensively, the Colts displayed the type of offense general manager Ryan Grigson envisioned when he put the team together. Ahmad Bradshaw rushed for 95 yards -- the highest total by any running back this season -- as the Colts had more rushing yards (179) than passing yards (157) in a game for the first time since the 2011 season.
No. 8 in the top-10 key plays of the season: Quarterback Andrew Luck suckers the 49ers.
The play of the game came when Luck led the Colts down to San Francisco's 6-yard line. Luck was under center yelling "sucker" before he faked the handoff to Bradshaw, rolled to his left and went in untouched to give the Colts a 20-7 lead with less than five minutes remaining. Luck capped the touchdown run off by spiking the ball in excitement.
"Long play call and then I heard 'sucker' at the end of it," Colts coach Chuck Pagano said the day after the game. "As soon as I saw him in the end zone and [spiking] the ball, it felt awesome."
Luck's touchdown ended an 11-play, 80-yard drive that chewed up more than seven minutes off the clock for the Colts.
