In a battle between two first-round quarterbacks, Luck shined in front of the home crowd, connecting with Reggie Wayne and T.Y. Hilton for touchdowns, converting a staggering 12 of 18 third downs, snapping Cam Newton's rookie record for passing yards in a game, and remarkably keeping the Colts in the hunt for the playoffs.
The Colts grabbed an early first quarter lead when the first overall pick connected with Wayne for a nine-yard touchdown that made the score 10-3, but Tannehill - who had his own superb day in defeat - helped the Dolphins respond in emphatic fashion.
Tannehill connected with Charles Clay on a 31-yard touchdown to tie the score, and, after a Colts field goal, Bush flashed vintage speed and elusiveness on an 18-yard touchdown run where he left at least four Indy defenders grasping at air.
An Adam Vinateri field goal before the half gave the Dolphins a 17-13 lead at half - but that margin wouldn't last.
Late in the third quarter, Luck flung a prayer into double coverage that found the hands of fellow rookie T.Y. Hilton for a 36-yard touchdown to make the score 20-17 and send the Colts into the final stanza with a lead and ever-expanding playoff hopes.
After both teams traded field goals in the fourth quarter to make the score 23-20, the Dolphins had one final chance to score and steal the win from Luck's hands, but a fourth-and-15 pass came up one yard short and the Colts sealed their fifth win of the year.
Fantasy studs: Andrew Luck headlined the day, and all of the Colts receivers benefitted from his phenomenal performance. Reggie Wayne had seven catches for 78 yards and a touchdown, Hilton had six catches for 102 yards and a score, Donnie Avery, who left the game with a hip injury, had five catches for 108 yards, and Dwayne Allen caught six balls for 75 yards. Brian Hartline had a nice day for the Dolphins, catching eight passes for 107 yards.
Fantasy duds: The Colts running backs were unspectacular - Vick Ballard led all runners with 16 carries for 60 yards.
Did they cover?: The Dolphins were favored by two points, and thus did not cover.
