Five teams moved to 4-0. But which are for real? Aaron Rodgers — still without an interception — and the Green Bay Packers sure seem to be. The Atlanta Falcons also appear to be under new coach Dan Quinn, thanks in part to giving Matt Ryan and Julio Jones a reliable ground game; second-year back Devonta Freeman ran for three TDs in a 48-21 victory over Houston and already has an NFL-high seven touchdowns, the first player in a decade with that many on the ground by Week 4. The jury's still out on the Broncos, Bengals and Panthers, who haven't played anyone good yet. But we'll know a lot more a month from now, because Cincinnati faces Seattle in Week 5, Carolina plays the two-time reigning NFC champ in Week 6, and Denver takes on Green Bay in Week 7.
