15. New England Patriots (2012)
The New York Giants were the bane of Tom Brady’s existence. On paper, the franchise had no right to beat the superior Patriots’ team. However, they pulled off the unlikely on two occasions when it counted. The second came in Super Bowl XLVI in Indiana. This wasn’t as historical as their first achievement but it was still a great win (via ESPN).
Many people love to say that Eli Manning wasn’t a great quarterback. This is probably true but he did pick important times to overperform. Nobody can claim that he didn’t deliver in Super Bowls. After the Patriots brought the game back to 17-15, the Giants consolidated. This was a missed opportunity for New England because they had a superior roster.
