4. Atlanta Falcons vs. New England Patriots (2017)
The Falcons threw away a Super Bowl win in 2017. It appeared as though Dan Quinn’s men were on course for a famous victory. They were blowing the Patriots away with a 28-3 lead before they had a meltdown. Maybe they didn’t like the Lady Gaga Halftime show, because something went seriously wrong.

Atlanta allowed the Patriots to maintain momentum as they sent the game to overtime. It also didn’t help that Quinn and his staff made some questionable calls. Then, New England won the game in overtime after they won the coin toss. It was a brutal way for the Falcons to lose but it was their fault (via Sporting News).
