With 14 games in the books, the No. 1 overall pick has turned the Colts from the worst team in the league to a 9-5 squad in position to make the playoffs.
Despite throwing for nearly 4,000 yards and leading his team to some incredible late-game victories, Luck still has some big flaws to correct if the Colts have any hope of making some playoff noise.
At first glance, Luck's numbers appear damn impressive for a first-year quarterback: 3,978 passing yards, 233 rushing yards and 25 total touchdowns.
The biggest hole in the former Stanford Cardinal's resume is turnovers.
Ironically, Luck is tied with Drew Brees for the most interceptions (18) in all of football.
It should come as no surprise that in the Colts' five losses, Luck has thrown the ball to the other team nine times, including three games in which he's tossed multiple picks.
No matter how talented a quarterback is, turning the ball over is a death sentence in the NFL.
Those turnovers, combined with fumbles by Stevan Ridley and Shane Vereen, played a huge factor in New England falling to San Fran.
Luck has a bit of a gunslinger mentality, but like any good quarterback, he needs to cut down on the turnovers and value ball security come playoff time.
Along with ball security, accuracy is one of the most important traits for a quarterback, and Luck's 54.6 completion percentage simply isn't good enough.
Regarded as one of the most accurate and efficient college quarterbacks of all time, Luck's accuracy has slipped significantly in the second half of the season.
In five games since posting a 69.2 completion percentage in a 27-10 victory against Jacksonville, the Colts signal-caller has completed just 49.5 percent of his passes.
Some of that blame falls on his young receiving corps, which includes a pair of rookie tight ends in Dwayne Allen and Coby Fleener and first-year receivers T.Y. Hilton and LaVon Brazill.
Reggie Wayne has been a godsend for Luck, often making spectacular catches in spurts, but Luck has had trouble connecting consistently with some of his other targets.
For a team that was expected to win six or seven games just a year after going 2-14, a 9-5 record and likely wild-card berth is a pleasant surprise.
In order to make a serious playoff push, however, the team's franchise savior has to cut down on turnovers and be more accurate with his passes over the next few weeks.
