Also moving up the rankings were Minnesota and Pittsburgh. The Vikings, a surprising 4-1, advanced six places to eighth, and the Steelers moved up six spots to ninth after their win over Philadelphia.
Atlanta may be 5-0, but until the Falcons win a playoff game there will be questions.
Says Clark Judge of CBSSports.com: "Let's just fast forward to the playoffs so we can see if Matt Ryan can do there what he does the first 16 games of the season."
The 49ers have a loss, but two voters had them first.
"Niners have outscored last two opponents by a combined 79-3. Right here, right now, they're the most complete team out there," said Newsday's Bob Glauber, one of the 49ers' backers.
Buffalo had the biggest drop, seven places to 27th after a 45-3 loss to the 49ers.
Cleveland, the league's lone winless team, is 32nd and last.
"As the NFL's only remaining winless team, they are now officially the favorite in the Geno Smith sweepstakes," said Dan Pompei of the Chicago Tribune.
