Biggest Upsets in NFL Betting History

Super Bowl XLII – Giants vs. Patriots

Look: the Patriots entered the 2007 championship with a perfect 16‑0 record and a 14‑point spread. The Giants, a 10‑point underdog, snatched a 17‑14 win and shattered a nation’s myth. Bookmakers lost millions, and anybody who ignored the “Giants are a nightmare” line paid for it. Here is the deal: a 21‑point swing in one game rewrote the betting playbook.

Super Bowl XLVI – Same Rivalry, Same Shock

And here is why the Patriots aren’t invincible. In 2012, the odds still favored New England by 12 points. Eli Manning’s late‑game heroics turned a 21‑17 final into another upset, draining the sharp money on the underdog. If you thought the first was a fluke, the second proved the market can be duped twice in a decade.

Super Bowl 50 – Broncos vs. Panthers

By the way, the Panthers were 5‑point favorites in 2016, yet the Broncos, led by a relentless defense, delivered a 24‑10 rout. The spread held, but the money line collapsed, leaving high‑rollers scrambling. The lesson? A stout defense can annihilate a high‑scoring offense faster than a kicker can say “extra point.”

Super Bowl LII – Eagles vs. Patriots

Fast forward to 2018: the Eagles, underdogs by 3.5 points, shattered the Pats with a 41‑33 offensive fireworks display. The game itself was a scoring marathon, but the underdog line held, and those who hedged early walked away with sweet profit. That upset cemented “defensive lapses matter more than celebrity coaches.”

2020 Wild Card – Bills vs. Ravens

Now, you might think the playoffs are a safe haven for favorites, but the Buffalo Bills entered as 10‑point underdogs against the Baltimore Ravens. They eked out a 17‑16 win, and the line moved like a freight train. Sharp bettors who backed the Bills at -110 saw a 19% return, a rare nugget in the postseason.

Takeaway

Bottom line: whenever a team rides a historic streak, keep an eye on the “overwhelm” factor—injuries, weather, or a single play can flip the script. Spot the spread that feels too tidy, and you’ll find the edge. Start betting the line, not the hype, and you’ll lock in profit.
