In Week 1, the San Francisco 49ers had the most impressive outing in regards to the NFC West. A win over the Green Bay Packers in Lambeau Field is basically the best win you can get today in the NFL, so they have a clear leg up on the rest of the division. But the 49ers face another tough matchup in the Detroit Lions, and there's something of a rivalry there. Should they falter, the rest of the division might have a chance to play catch-up.
Unfortunately for them, they've got some tough matchups. The Arizona Cardinals were the only other NFC West team to pick up a win in Week 1, and they've got the New England Patriots on the road. Arizona's narrow win over the Seattle Seahawks won't give anybody the confidence that they can stop New England. Russell Wilson may be better than originally advertised, but he's a far cry from Tom Brady and his plethora of top tier targets.
Arizona might have the best player in the game, as they often do thanks to Larry Fitzgerald, but the rest of the top talent is few and far between. They'll have trouble snagging a 2-0 record and a potential lead in the NFC West.
The St. Louis Rams and Seahawks both were on the losing end of games in Week 1. St. Louis actually showed strong play against Detroit and were 20 seconds away from picking up a win, so they might actually have a shot to best Robert Griffin III and the Washington Redskins. Seattle also isn't fighting an insurmountable battle when they take on the Dallas Cowboys.
It isn't out of the question to think that the entire NFC West could be at 1-1 after two weeks, but that all hinges on a 49ers loss and three other teams who aren't the favorites pulling out wins.
