Some of that blame in recent years for being unable to cross that threshold has been directed at head coach Sean McDermott, but that largely appears to be external. Within the walls of Highmark Stadium, there's plenty of confidence in McDermott, starting at the very top with quarterback Josh Allen.

As the clock ticked down, the Chiefs seized the lead with a 35-yard field goal from Harrison Butker, making it 32-29 in their favour. With 3:33 remaining and the Bills trailing by three, Allen had the opportunity to orchestrate a game-winning drive and propel his side to the Super Bowl.

Josh Allen could take plenty of satisfaction from a season in which he became the betting favorite for MVP and the Buffalo Bills defied the doubters who predicted a down year.
