Yes, they are the only undefeated team in the NFL. But the Power Poll is not supposed to be a list of the standings. It's a list of who you think is the best team in the league at the current moment. I still have them fourth. I like the San Francisco 49ers first and no one seems to agree.
The case against Atlanta: Teams like the Oakland Raiders and Carolina Panthers outplayed them in the Georgia Dome. Atlanta deserves a lot of credit for finding a way to win those games, but to ignore that luck is a huge factor in close NFL games is to ignore reality. Five of the Falcons' wins have been by one score. They have only played one team all season that currently has a winning record: the Denver Broncos.
The Falcons are very solid on both sides of the ball. That's why they are in the top five. Top five is good. But they are lucky to be 8-0, and I don't think they are particularly better than the top-shelf of teams, including the 49ers, Houston Texans, New England Patriots, Green Bay Packers, Chicago Bears and New York Giants. This is a debate we could be having for a while because Atlanta has a great chance to win the No. 1 seed in the NFC.
