Welcome to Week 4 of the NFL regular season. This past weekend we learned that the Miami Dolphins' offense can (and will) put up 70 points, the Kansas City Chiefs' offense has awakened and the Chicago Bears' offense needs ... help.
With a big win against the Dallas Cowboys, the Arizona Cardinals have risen from the bottom of this week's Power Rankings. Also of note, the once top-10 Jacksonville Jaguars took a tumble after suffering defeat to division rival Houston Texans, and the middle of the rankings played musical chairs yet again.
