Home-field advantage helped in the NFC wild-card games.

But not for the team you expected to benefit.

Sub-.500 Seattle pulled one of the biggest upsets in playoff history Saturday, knocking off defending Super Bowl champion New Orleans, 41-36.

The Seahawks only made the playoffs because they won the awful NFC West — and got to host the first-round game as a result.

Philadelphia, meanwhile, actually earned its home game. It did little good for the Eagles, who fell to the Packers, 21-16.
