12. Indianapolis Colts (2010)
The New Orleans Saints hold Super Bowl XLIV in their hearts because it was their first NFL title win. Indy carried the favorites tag into the game but had one of the biggest choke jobs instead. Peyton Manning threw a key fourth-quarter interception that cost his team dearly. Meanwhile, Drew Brees won the Super Bowl MVP award for his excellent display (via N.Y. Times).
In the end, the Colts endured a heavy 31-7 defeat. Their offense failed to fire and made costly mistakes. Brees completed a record-equalling 32 passes as his legend rose to a new level. It was disappointing for Manning’s fans because they wanted their hero to win another ring. Finally, he got his second ring, but not until after he moved to Denver.
