The Greatest Single-Postseason Runs in NFL History

A perfect 20-0 season is one kind of greatness: sustained, flawless, twenty games without a crack. But the NFL playoffs also reward a different kind — the improbable, compressed run where a team that had no business reaching the Super Bowl wins three or four straight elimination games and does it anyway. These are the runs that make single-elimination football what it is.

2007 New York Giants — the run that ended a perfect season

The most consequential postseason run of the modern era belongs to a team that finished the regular season 10-6. The Giants entered the playoffs as a #5 seed and won three straight road games just to reach the Super Bowl. Then they beat the 18-0 New England Patriots 17-14 in Super Bowl XLII, ending the only real bid at a perfect season the 16-game era ever produced.

That game is the reason the near-miss and the great run are two sides of the same coin. New England’s flawless year and New York’s improbable one collided in a single February night, and the lower seed won. For the Patriots’ side of that story, see our look at the 2007 Patriots’ 18-1 season.

2005 Steelers and 2010 Packers — the #6 seeds who ran the table

Twice, a team has won the Super Bowl from the sixth and lowest seed in its conference — the hardest possible road, with no bye and no home games. The 2005 Pittsburgh Steelers won three straight road games in the playoffs before taking Super Bowl XL, becoming the first #6 seed to win it all. Five years later, the 2010 Green Bay Packers did it again, also as a #6 seed, winning Super Bowl XLV.

Both runs underline the same point: a bye and home field are enormous advantages, but they are not requirements. A hot team playing its best football in January can win the whole thing from the bottom of the bracket — it just has to be nearly perfect for four straight weeks to do it.

1980 Raiders — the first wild card champion

Before any of that, the 1980 Oakland Raiders became the first wild card team ever to win a Super Bowl, taking Super Bowl XV. At the time it was a genuinely new idea that a non-division-winner could survive the postseason gauntlet and finish as champion. Every deep wild card run since traces back to that team proving it was possible.

What these runs share

None of these teams earned a first-round bye, which meant every one of them had to win an extra elimination game the top seeds never played — the very game that separates a 20-0 path from a 21-0 one. We break down why the bye matters so much in our guide to the first-round bye advantage.

They also share the thing that makes the format cruel and thrilling at once: single elimination. There is no series to settle down into, no best-of-seven to absorb a bad night. Win, or the run ends.

Great runs versus perfect seasons

Here is the distinction that matters for anyone chasing 20-0. A great postseason run needs a team to be brilliant for three or four games. A perfect season needs it to be brilliant for twenty — the entire regular season plus the same January gauntlet. That’s why deep runs, rare as they are, still happen every few years, while a wire-to-wire perfect season has happened exactly once. For the teams that reached January still unbeaten and left with a loss, see our rundown of every near-perfect season.

The great runs remind you how much can go right in a short stretch. The near-misses remind you how little has to go wrong to end a long one. A 20-0 season lives at the intersection: it demands both a flawless season and a flawless January.
