1. San Francisco 49ers
Season Outlook:
The San Francisco 49ers stay atop the power rankings after a second straight win against a 2011 playoff team.
The Green Bay Packers couldn't move the ball against the 49ers' defense, and neither could the Detroit Lions. Holding the powerful Lions' offense to field goals just goes to show the sheer might of the San Francisco defense. If Green Bay and Detroit can't score on the 49ers, who can?
What's more terrifying for opponents is that the San Francisco offense is much better this year. Michael Crabtree is playing like the Top 10 draft pick the team spent on him. Frank Gore and Kendall Hunter are a dynamic duo at the running back position and Vernon Davis provides the spark as a game-changing tight end.
The 49ers might not go undefeated, but they are undoubtedly the team to beat right now.
