My team is out, so my interest is a bit muted. I also don't think the Seahawks' victory is any kind of beginner's luck. They're not better than the Saints, either. It's just that a lot of trends converged in that game that favored the Seahawks.
1. They were at home, and statistically have the best home-field advantage in the NFL by a significant margin.
2. The Saints are a dome team, and dome teams historically struggle outdoors on the road in the playoffs.
3. The Saints were exceptionally banged up, even by the standards of the end of the year when every team is banged up. Their top two running backs were hurt coming into the game, and their next two left the game with injuries. They also missed one of their best defenders, Malcolm Jenkins.
4. The Seahawks took advantage of Jenkins' injury by repeatedly targeting Roman Harper with success.
5. The Seahawks, knowing that they are not talented enough to beat the Saints by playing it safe, pulled out a couple of trick plays and risky plays. Those gambles paid off.
This is why I won money on the Seahawks
For the record, none of these advantages carry over into the Seahawks' game with the Bears. They did beat the Bears in Chicago this season, but the Bears were a very different team then. I expect the Bears to enjoy the comfortable victory most expected from the Saints.
