4. Giants vs. Patriots (2009)
The Patriots were a game away from being the greatest football team ever. After they went through the entire regular season unbeaten, they reached the Super Bowl with an 18-0 record. They came up against Eli Manning’s Giants who were major underdogs. But they belied their status to seal one of the most unlikely wins in the big game’s history.

A lot of fans like to disparage Manning but he’s a two-time Super Bowl MVP award winner for a reason. He came up clutch in this game as the Patriots choked badly. Viewers witnessed the iconic ‘helmet catch’ as David Tyree secured the ball against his headgear. Furthermore, New York put Brady under intense pressure and made life very uncomfortable for him (via Boston Globe).
