Those three teams kept their spots in the AP Pro32 on Tuesday.
In balloting by 12 media members who regularly cover the NFL, the Patriots finished ahead of the Packers and Broncos for the second consecutive week.
''More insane numbers from Tom Brady, who throws for the second-most yards of his career in 40-32 win over Bills,'' Newsday's Bob Glauber said.
The Packers kept the Seattle Seahawks winless with a 27-17 victory in a rematch of last season's NFC title game. The Seahawks dropped from fifth to eighth.
''A big win over Seattle helps ease a little bit of the pain of last year's playoff loss,'' ESPN's Herm Edwards said.
The Bengals are underdogs going into Sunday's game at the winless Ravens.
''We'll find out about them this week in Baltimore,'' NBC Sports' Tony Dungy said.
The Cardinals have a two-game lead over the Seahawks in the NFC West.
''If Carson Palmer stays healthy, look out NFC,'' Ira Kaufman of the Tampa Tribune said.
Arizona's quarterback is off to a strong start with 492 yards passing and seven TDs in two games.
The Cowboys traded for Matt Cassel on Tuesday to add depth at quarterback.
''The Cowboys are 2-0 on the field but 0-2 in the training room, having lost QB Tony Romo and WR Dez Bryant for what could be the next two months with injuries,'' said Rick Gosselin of The Dallas Morning News.
''Found a defensive star in (Ryan) Shazier,'' Fox Sports' John Czarnecki said.
The linebacker had a career-high 15 tackles with a sack and a forced fumble.
''That's what happens when you pay $127 million for your secondary,'' Jenny Vrentas of The Monday Morning Quarterback said after New York shut down Andrew Luck.
''This Jets defense will be even better when Sheldon Richardson returns.''
''I love that the Falcons kept their focus after a big Week 1 win over Philadelphia,'' Foxsports.com's Alex Marvez said. ''It speaks volumes about how positively Dan Quinn has affected the team.''
