4. Buffalo Bills: 1993 NFL Wild Card
The Bills looked like they had absolutely no chance. They were losing 3-35 against the Houston Oilers with a backup QB, Frank Reich. The Bills just lost the super bowl the year before appeared inevitably helpless. Yet, the backup QB and the Bills managed to keep fighting on their home field to win this game 41-38 while Hall of Fame QB Jim Kelly was out with an injury.
