Falcons, Cardinals and Texans maintain perfect starts Sun Sep 30, 2012 8:48pm EDT (Reuters) - The Atlanta Falcons, the Arizona Cardinals and the Houston Texans maintained their perfect starts with victories in the NFL on Sunday while the New Orleans Saints misery continued as they slumped to 0-4 with a loss at Green Bay. The Falcons needed a late field goal to beat the Carolina Panthers and the Cardinals won in overtime against Miami while Houston marched to 4-0 for the first time in franchise history with a 38-14 win over Tennessee. The Cardinals faced a more-dangerous-than-expected Miami, whose rookie quarterback Ryan Tannehill threw for 431 yards and one touchdown while wideout Brian Hartline put up a franchise-record 253 yards receiving. A 15-yard touchdown pass from Kevin Kolb to Andre Roberts with just 22 seconds of regulation remaining saved the Cardinals and took the game into overtime. After Arizona failed to make use of its first possession, Tannehill was intercepted by Kerry Rhodes at midfield and former Dolphin Jay Feely converted a 46-yard field goal for victory. If Houston and Arizona are surprises at 4-0, it is equally unexpected to see New Orleans at 0-4. The Saints' latest setback came with a 28-27 loss at Lambeau Field against a fired-up Green Bay Packers, determined to make up for Monday's infamous loss at Seattle. An 11-yard pass from Aaron Rodgers to Jordy Nelson won the game for the Packers although the Saints had their chance. Garrett Hartley put a 43-yard field goal attempt between the posts but a 10-yard penalty for holding by the Saints forced a re-kick and after a five-yard encroachment penalty against the Packers, Hartley missed a 48-yard kick. Saints quarterback Drew Brees equaled Hall of Fame quarterback Johnny Unitas' record of throwing a touchdown pass in 47 consecutive regular season games. There was more kicking drama in the Washington Redskins' dramatic 24-22 win in Tampa against the Bucs. Redskins kicker Billy Cundiff missed field goal attempts from 41, 57 and 31 yards but he delivered when it mattered the most with his 41-yarder in the final seconds taking Washington to 2-2. Quarterback Peyton Manning threw for three touchdowns and 338 yards in the Denver Broncos' 37-6 rout of the Oakland Raiders.
