7. Carson Palmer
The Carolina Panthers annihilated the Arizona Cardinals in the 2015 playoffs. A big part of this defeat was the fact that Palmer, the Cardinals’ quarterback, had an awful game that tarnished fans’ perceptions of him. After patchy performances for the Cincinnati Bengals and Oakland Raiders, Palmer reignited his career in Arizona. Cam Newton won the 2015 NFL MVP award but Palmer was a close contender after his best year as a pro.
But it was probably just as well that he didn’t win it because his performance in the NFC Championship game was atrocious. Palmer turned the ball over six times as the Panthers hammered the Cardinals and showed just why Newton won the MVP award instead. It was an embarrassing display for everybody involved. Meanwhile, Palmer never played in the postseason again after the game tarnished his rep.
