NFL superstar helps flag down some training tips

The National Football League sees exuberant children as a perfect counterpoint to the popular perception in China that American gridiron is a violent, dangerous game－and one of the NFL's biggest superstars was in Shanghai last weekend to prove it.

Hundreds of kids chanted "Wil-son! Wil-son!" when Seattle Seahawks quarterback Russell Wilson entered the stadium to help launch another season of NFL flag football, a "no-tackle" variation of the game in which players are "downed" when a flag worn around their waist is pulled off by an opponent.

Launched in China in 2008, NFL flag football was originally limited to university campuses, but has since expanded to seven age groups, from preschoolers to adults.

"It's great be here, and I'm excited to see versions of American football being played all over the world," said Wilson, who steered the Seahawks to the 2013 Super Bowl championship.

"It's a healthy sport for kids to get physically fit and learn teamwork," added the 29-year-old, who supervised a youth training session after the launch ceremony.

"I think there's a lot of good talent here. I saw a lot of kids catching and throwing the ball nicely. I will definitely return to see how they're progressing."
