"This year, some things have happened for us and it's like, wow, this may be destiny," McAllister said.
"It means everything," Bush said. "All that stuff we went through as a team, these are the type of games we live for. And this game is even bigger for the city."
The Saints are the first team in NFL history to make a conference championship after losing 13 or more games the previous season.
With victory secured for the Saints (11-6) on McAllister's powerful rushes for a clinching first down to run out the clock, team owner Tom Benson did his "Benson Boogie" on the field. The players hugged and saluted their long-suffering fans while a jazz band belted out tunes.
"I think it means a tremendous amount," quarterback Drew Brees said. "You could see it and feel it after the game, people still standing and yelling and screaming."
It was the veteran McAllister with his two touchdowns and team playoff mark of 143 yards rushing, and the rookie Bush with his collection of magnificent moves, that made the difference in the raucous Superdome.
"It's my first opportunity to be in the playoffs, I didn't want to be one-and-out," McAllister said. "I didn't want to say, 'If I had done this or prepared differently, we would have been successful.'
"It's just the determination of this team and this city -- to give them everything we have."
McAllister scored on a 5-yard run and an 11-yard pass in the third quarter.
The Eagles, who won six in a row after losing quarterback Donovan McNabb, got a superb performance from Westbrook, who rushed for 116 yards and scored twice, including a 62-yard run that was a franchise playoff record.
McAllister, who missed 11 games last season with a knee injury, has been overshadowed by the spectacular Bush and surprising seventh-round draft pick Marques Colston. But he came through when he was needed most against the NFC's hottest team.
So did Bush, the 2005 Heisman Trophy winner whose arrival after Houston passed on him in the draft lifted the spirits of the Gulf Region. He scored on an eye-popping 4-yard run in the first half and had an equally scintillating 25-yarder to set up one of John Carney's two field goals.
So let the parties begin -- at least until the conference title game.
"There's still a lot of work to be done," said Payton, the NFL Coach of the Year. "We just hope we can put a little kick in their step Monday and Tuesday, and give them something to look forward to next weekend."
McAllister's 28-yard run set up Carney's 33-yard field goal for an early lead. And Carney's 23-yarder in the second quarter that made it 6-0 also was the result of a long run -- by Bush.
The rookie started to his right, but with a bunch of Eagles in his way, he reversed field. After faking going down the middle, he sped to the left sideline and picked up 25 yards.
Brees then threw his best pass of the half for a 35-yard gain to Devery Henderson behind Rod Hood, who was in for injured Lito Sheppard, Philadelphia's best cover cornerback.
Garcia trumped that with his perfect pass to Stallworth beyond Fred Thomas, the longest pass play and longest touchdown in Philly's playoff history.
But Philly's resourcefulness on third downs highlighted an 80-yard drive to the go-ahead TD on a 1-yard leap over the pile by Westbrook. Garcia found Reggie Brown for 32 yards and Hank Baskett for 25 on third-down plays, with both receivers wide open.
The half ended in confusion. First, punter Steve Weatherford gained 15 yards and a first down when he saw his kick was about to be blocked and he took off to the right. Then Brees' desperation pass into a group in the end zone momentarily was caught by Colston. William James then ripped it loose, and the Saints stayed on the field hoping for a video review by the replay booth. The Eagles, meanwhile, headed to the locker room, soon followed by the officials.
- Eagles All-Pro tackle Shawn Andrews injured his neck in the first half and was taken to a hospital with swelling.
- Eagles LB Shawn Barber injured his ankle.
- The Saints also beat the Eagles 27-24 here during the regular season.
- Stallworth finished with 100 yards on three catches for Philly, while Colston had five for 55 and seldom-used tight end Billy Miller caught four passes for 64 yards for the Saints.
