9. New Orleans Saints vs. Indianapolis Colts (2011)
Another regular-season defeat, this one makes the list because it was a massive blowout. The Colts were accustomed to success with Peyton Manning as their quarterback. However, the world was very different without him. This was a devastating rout as Drew Brees threw five touchdowns.

Meanwhile, Curtis Painter was appalling as the Colts went 0-7. This was a soul-crushing day for their fans considering the prestige of the franchise. Manning sat above and watched the agonizing victory unfold. The Saints set a record for points and victory margin as they won 62-7 (via Fox Sports).
