9. Patriots vs. Chiefs (2018)
New England inflicted another cruel defeat on an AFC rival in 2018. This time their victims were the Chiefs after a brutal overtime period. Kansas City was the better team throughout this game but they failed to seal the deal. This proved costly because Tom Brady is one of the best clutch players in NFL history. In the end, the quarterback made the difference (via Boston.com).
The game went to overtime and Brady proved to be clinical. It’s usually the case that teams win the game after winning the toss. This one was no different as Brady proved to Patrick Mahomes that he is peerless. Kansas City fans will never forget the agony of this defeat. Fortunately, they rebounded the following season and won their first Super Bowl in 50 years.
