Coming off their comeback road win over the Dolphins, the Saints went home for a Week 8 NFC South duel with the Atlanta Falcons on Monday night. New Orleans would initially trail in the first quarter as Falcons running back Michael Turner got a 13-yard touchdown run, yet the Saints answered with running back Pierre Thomas getting a 22-yard touchdown run. Atlanta would come right back as quarterback Drew Brees was sacked by free safety Thomas DeCoud, causing him to fumble and allow defensive end Kroy Biermann to return the ball 4 yards for a touchdown. In the second quarter, New Orleans would go on a rampage with Brees' 18-yard touchdown pass to wide receiver Marques Colston, running back Reggie Bush's 1-yard touchdown run, and cornerback Jabari Greer's 48-yard interception return for a touchdown. However, the Falcons began to get back into the game with quarterback Matt Ryan finding wide receiver Roddy White on a 68-yard touchdown pass in the third quarter, followed by kicker Jason Elam booting a 25-yard field goal. Fortunately, cornerback Tracy Porter's key interception (helped from linebacker Jonathan Vilma's tip) lead to Brees finding Thomas on a 1-yard touchdown pass. Even though Atlanta crept closer with Elam nailing a 40-yard field goal and recovering an onside kick, free safety Darren Sharper's interception sealed the tight victory. With the win, the Saints improved to 7-0 (tying their best start since 1991).
