Giants squeak by Cowboys; Week 8 NFL roundup ARLINGTON, TexasLawrence Tynes kicked two of his five field goals in the fourth quarter and Eli Manning and New York remained undefeated at Cowboys Stadium with a 29-24 win after blowing a 23-point lead. The Giants overcame a fourth-quarter deficit to win for the 20th time in Manning's career. None were quite like this one. New York (6-2) led 23-0 just 2 minutes into the second quarter when defensive end Jason Pierre-Paul returned an interception 28 yards for a touchdown. That was the third interception thrown by Tony Romo, among six turnovers by Dallas (3-4). The NFC East-leading Giants didn't score again until Tynes kicked a 43-yard field goal with 10:20 left for a 26-24 lead. He added a 37-yarder after Stevie Brown recovered a fumble. Dallas celebrated what seemed to be a 37-yard touchdown catch by Dez Bryant with 10 seconds left. But the play was reviewed, showing that Bryant's hand touched out of bounds first. Matt Ryan threw touchdown passes on Atlanta's first three possessions against Philadelphia and new defensive coordinator Todd Bowles, and the Falcons remained the NFL's only unbeaten team with a 30-17 victory over the Eagles on Sunday. The Falcons improved to 7-0 for the first time in franchise history while the Eagles (3-4) lost after a bye for the first time in 14 games under coach Andy Reid since 1999. Ryan finished 22 of 29 for 262 yards and three TDs for his first win against his hometown team in three tries. Michael Vick didn't turn the ball over for once, but he played so-so and failed to beat his former team in his second start against the Falcons since returning to the NFL in 2009. The Falcons scored on their first six possessions before punting for the first time with 5:35 left. Matthew Stafford threw a 1-yard touchdown pass to Titus Young with 20 seconds left. Zach Miller made a spectacular, 16-yard catch on a toss from Russell Wilson with 5:27 left to put the Seahawks ahead. Seattle (4-4) couldn't stop the Lions (3-4) on their last possession. Stafford led a 16-play drive that started at Detroit 20 with 5:27 remaining. The possession began with a 15-yard pass to Calvin Johnson and was kept alive with third-down conversion passes to Johnson in Lions territory and to Joique Bell to set up the winning score from just outside the goal line. The Steelers turned Robert Griffin III into just another rookie quarterback, swarming Washington's precocious star in a dominant win. Griffin completed just 16 of 34 passes for 177 yards and a score while managing 8 yards rushing. Pittsburgh quarterback Ben Roethlisberger had no such issues, throwing for 222 yards and three touchdowns as the Steelers (4-3) won consecutive games for the first time this season. Jonathan Dwyer added 107 yards rushing in his second NFL start. Pittsburgh jumped on Washington (3-5) early, scoring on its first four possessions and never letting Griffin get loose. Heath Miller caught four passes for 46 yards and his sixth touchdown of the season for the Steelers. Rookie Trent Richardson rushed for 122 yards and scored a touchdown in the Browns' soggy, wind-whipped win. Richardson, pulled last week at Indianapolis when he was ineffective because of a rib injury, carried 24 times as the Browns (2-6) won their second straight game at home - and first for new owner Jimmy Haslam. Richardson scored on a 26-yard run in the first quarter and the Browns were able to hang on despite not generating much offense in blustery, rainy conditions. The Chargers (3-4) dropped their third straight. San Diego had a final chance, but quarterback Philip Rivers' pass was batted away by Browns cornerback Buster Skrine with 1:24 left. Rivers finished 18 of 34 for 154 yards Tom Brady led touchdown drives on the first five possessions and New England cruised at Wembley Stadium. The Rams looked ready to put up a fight when Sam Bradford hit Chris Givens with a 50-yard touchdown pass on the opening drive. But Brady cut through the St. Louis defense at will to give New England a 28-7 lead by halftime, then hit Brandon Lloyd for a 9-yard score to start the third quarter. New England surpassed 350 yards of total offense for the 17th straight game, breaking an NFL record set by the Rams in 1999-2000.
