21. Jake Delhomme
The 9-7 Cardinals made it all the way to the Super Bowl in 2008. Kurt Warner’s brilliance helped them at key moments but they were lucky to make it so far. However, they could thank the Panthers’ Delhomme for helping them in their quest. The quarterback was dreadful when the Panthers and Cardinals met in the divisional round in one of the worst quarterback postseason displays ever.

Delhomme threw five interceptions against the Cardinals and was responsible for six turnovers. He was definitely not the same player who led the Panthers to a Super Bowl appearance in his very first season. While he was the Panthers’ best quarterback until Cam Newton came along, he sullied his fans’ appreciation of him with that awful display. Some games are just cringeworthy to look back on.
