I say "probably" because Andrew Luck wasn't really in the top-6 statistically, for any category. His stats this year were actually somewhat underwhelming: 12th in completions, 11th in attempts, 24th in completion percentage, 13th in yards. 15th in touchdowns. Despite that, his play itself – with the Colts, a team with the second most games lost to injury in the league – was enough to turn out 11 wins, including four against the Chiefs, Broncos, Seahawks, and 49ers.
In the AFC Wild Card win over the Kansas City Chiefs (1/4/14), Luck led the Colts to the second-largest comeback in NFL postseason history after trailing by 28 points in the second half. His 443 passing yards marked the second-most in franchise postseason history and the fifth-most in NFL postseason history. His four touchdown passes in the game tied for the second-most in franchise postseason history.
Regardless, it's a shame Luck wasn't voted in sooner; his accomplishments, on the team he leads, were (in my mind) greater than most of the quarterbacks who actually made the Pro Bowl. Consider this: midseason, following Reggie Wayne's injury against Denver, Indy's starting wideout was Darrius Heyward-Bey.
Darrius Heyward-Bey. For leading his team to any more wins, Luck should have been considered for MVP.
