If Andrew Luck was having any second thoughts about his stunning decision to retire from the NFL, he's probably not having them anymore after the way fans in Indianapolis treated him after the Colts' preseason game against the Bears on Saturday. 

As Luck began to make his way off the field following the 27-17 loss, fans at Lucas Oil Stadium started to boo their former quarterback. The news of Luck's retirement broke during the fourth quarter of the game, and clearly, Luck's decision to hang up his cleats for good didn't sit well with the fans. 

The fact that Colts fans decided to boo Luck makes zero sense. In seven seasons with the team, he led them to the playoffs four times, and in the three years he didn't take Indy to the postseason, it was because he missed games due to injury. In the end, the injuries proved to be too much.
