NEW ORLEANS — Robert Griffin III brought his Heisman Trophy swagger to New Orleans and made his NFL debut look like a Big Easy.
Showing a veteran’s composure by scrambling only when necessary, the dynamic Redskins rookie quarterback tormented the New Orleans defense with 320 yards passing and two touchdowns, and Washington held on for a 40-32 victory over the Saints on Sunday.
‘‘I've won a high school state championship and a bowl game in college, but to play in the NFL, the pinnacle of it all, and win your first game against a Hall of Famer in Drew Brees, it’s at the top,’’ Griffin said while cradling the game ball he had just been given.
New Orleans hoped to open the season with a defiant show of force in the wake of the bounty scandal that overshadowed its offseason. The Saints also got a boost Friday when a three-member appeals panel reinstated defensive end Will Smith and linebacker Jonathan Vilma, who had been suspended for their roles in the Saints’ alleged pay-for-pain bounty program.
Smith started, while Vilma, deemed unfit to play after offseason knee surgery, received a rousing ovation when he walked onto the field to lead the Saints’ traditional pregame ‘‘Who-dat’’ chant.
Instead of riding that emotional high, the Saints spent much of the game trying to keep up with a Redskins offense powered by youth. Opening with several short, quick throws, Griffin, the No. 2 overall draft pick, completed his first eight passes. On his seventh pass, released just before he was leveled by blitzing safety Malcolm Jenkins, Griffin hit Pierre Garcon in stride over the middle for an 88-yard touchdown, tying the second-longest scoring pass by a quarterback making his NFL debut.
‘‘It’s great for any quarterback to get a couple of easy passes at the beginning of a game so you can get into a rhythm,’’ Griffin said. ‘‘They were giving us those looks and I took advantage of them.’’
Griffin finished 19 of 26 with no interceptions and a passer rating of 139.9. He also scrambled for 42 yards.
‘‘Robert did an unbelievable job to play the way that he did in his first game in the National Football League,’’ said Redskins coach Mike Shanahan, marveling at ‘‘the poise that he played with and some of the throws that he made.’’
Washington rookie Alfred Morris rushed for 96 yards and two touchdowns. Receiver Aldrick Robinson, a second-year pro making his NFL regular-season debut, had a 5-yard touchdown catch among four receptions for 52 yards.
Brees quickly dismissed the idea that disruptions from the bounty probe, which resulted in a season-long suspension for coach and offensive mastermind Sean Payton, was to blame for New Orleans’s shaky start.
‘‘Not at all. It’s the NFL. You better bring it every week,’’ Brees said.
‘‘We knew the type of team they were. We knew the type of defense they were. They just came in and played better than we did, made fewer mistakes than we did, made more plays than we did.’’
