Hoping to rebound from their home loss to the Ravens, the Saints flew to Raymond James Stadium for an NFC South rematch with the Tampa Bay Buccaneers.  In the first quarter, quarterback Drew Brees completed a 15-yard touchdown pass to rookie WR Marques Colston and a 52-yard touchdown pass to WR Devery Henderson.  In the second quarter, kicker John Carney would complete a 46-yard field goal to give New Orleans a 17-0 lead.  Yet, the Bucs started to fight back, as quarterback Bruce Gradkowski completed two touchdown passes to WR Joey Galloway (a 44-yarder and a 17-yarder).  In the third quarter, the Saints would take over for the rest of the game, as RB Deuce McAllister completed a 3-yard touchdown run, while Brees completed a 45-yard touchdown pass to Henderson.  After a scoreless fourth quarter, New Orleans would get the sweep over Tampa Bay and improve to 6-2.
