After a spectacular offensive performance all around by the Saints against the 49ers, they headed to Dallas to face off against their NFC rivals the Cowboys. The Cowboys started off strong with a 77-yard Julius Jones run, but they were silent for the rest of the quarter.  In the second quarter, a shaky Saints team suddenly scored on all three of their drives: a 2-yard run from Mike Karney, a 3-yard pass from Drew Brees to Karney, and a 27-yard pass from Brees to WR Jamal Jones; and to cap it all off, Dallas kicker Martin Gramatica missed a field goal at the end of the half.  A surprising Saints team stymied the Cowboys to a field goal by Gramatica, and Reggie Bush quickly answered with a 61-yard catch for a touchdown.  Terrell Owens answered with a 34-yard touchdown catch. Mike Karney struck again with a 6-yard catch, and after a challenge by Sean Payton it was ruled a touchdown.  The Saints recovered an onside kick at the 40, and Devery Henderson caught a 42-yard pass and crawled in for a touchdown. With the blowout against the Cowboys, the Saints improved to 9-4 and are one game away from clinching the NFC South. Mike Karney was called by Drew Brees 'Mr. Touchdown,' because he had three touchdowns.
