Toon, a fourth-round pick in 2012 who spent his rookie season on injured reserve, started for Marques Colston, who has been getting extra rest because of an offseason foot injury. Stills started at wideout for the second straight game and hauled in Brees' lone scoring strike from 16 yards out.
"We asked them to do a lot. They were having to think a lot on the move," Brees said. "They did a great job adjusting to that and played with a lot of confidence."
Brees completed 78 percent of his passes (14 of 18), including a 56-yarder to Toon, setting up Mark Ingram's 2-yard TD run.
On his long catch, Toon beat former Saints cornerback Tracy Porter, who later left the game with a right groin injury. Raiders coach Dennis Allen said that was one of eight injuries -- three of them potentially serious -- for Oakland. In addition to Porter, Allen was particularly concerned about offensive tackle John Wetzel's knee injury and tight end David Ausberry's shoulder injury.
New Orleans' new defense under coordinator Rob Ryan thrived, sacking Matt Flynn five times in the first half.
"Some of it was different looks, some of it was guys getting beat and some of it was we have to recognize the pressure, find the hot receivers and get the ball out," Allen said, noting that Flynn twice did not see receivers open for potentially big plays. "I can't point to one individual aspect and say that was the issue."
"The difference between moving the ball and not moving the ball is just so small," Flynn said. "There are just some things we have to clean up. We know we can do a lot better."
"I wish we could have had more points," Brees said. "So there's still work to do."
Stills caught four passes for 64 yards, making challenging grabs along the sideline twice, once on his TD.
Flynn was back in the stadium where he won a national title with LSU in January 2008. It also was a homecoming of sorts for Allen, a former Saints defensive assistant under Payton for five years.
What helped the Raiders make a game of it was poor ball security by New Orleans. Second-year running back Travaris Cadet fumbled twice, resulting in one turnover. Oakland's second touchdown came when defensive end Ryan Robinson recovered Seneca Wallace's fumble, which was forced by David Bass on the 1.
Eddy Carmona's 46-yard field goal, which pulled Oakland to 23-17 at the end of the third quarter, was set up by Omar Gaither's interception of Seneca Wallace's tipped pass.
"I know it was a preseason game, but we did everything in the second half to allow them a chance to get back in the game," Payton said. "That frustrated me."
Wallace, competing with Luke McCown to back up Brees, was three of six passing for 32 yards in five scoreless series.
Notes: Allen said other Raiders injuries were: RB Darren McFadden (shoulder), LB Kevin Burnett (knee), CB Joselio Hanson (shoulder), DL Brandon Bair (hamstring) and Carmona (neck, leg). ... The game was the last called by retiring public address announcer Jerry Romig, who has handled those duties since 1969. The 83-year-old signed off by announcing the final score and added, "It's been fun. Good night. Love you." He will be succeeded by his son, Mark, in the regular-season opener against Atlanta.
