cool Drew Brees led a game-winning drive in the fourth quarter as the New Orleans Saints clinched a playoff berth with a 17-14 triumph over the NFC South Division-leading Atlanta Falcons Monday. After throwing interceptions on consecutive drives to allow the Falcons to surge ahead 14-10 in the fourth, quarterback Brees capped a 90-yard march downfield with a six-yard touchdown pass to Jimmy Graham with 3:28 remaining. The Saints stopped Atlanta on its next possession and then ran down the clock to hand the Falcons their first home loss of the season. Defending Super Bowl champion New Orleans (11-4) moved within one game of the Falcons in the NFC South.
