Peterson and about 10 of his teammates spent more than 30 minutes after practice working with about 50 athletes from Special Olympics Minnesota from across the state for a Punt, Pass and Kick clinic.
"This just gives us an opportunity to interact," Peterson said as he signed autographs. "These are some great athletes right here also. It's just fun to come out here, interact with these youngsters and have a good time."
Peterson helped the athletes, many of them with Down Syndrome, with their punting form, gave and received high fives, offered plenty of encouragement and even participated in a throwing contest in which two girls beat him.
"It was a blast," said one participant. "We love Adrian."
One of the participants presented Peterson with a folding picture frame, with the athlete in a Vikings jersey on one side and a drawing of Peterson on the other. Peterson also signed dozens of t-shirts and memorabilia, including an Oklahoma Sooners hat.
Peterson said it is "amazing" how much he has touched the lives of people in Minnesota in just more than a year since being drafted by the Vikings.
"That's one thing I'll look back on and thank God for putting me in a position to able to affect people's lives. How I was raised, just knowing that I'm going to be able to do that in the right way, it feels good."
Wide receiver Bernard Berrian was also a big part of the event, held on one of the outdoor practice fields at Winter Park. He was busy catching passes while other players were retrieving and holding for kicks and punts.
"It's definitely rewarding. I've been working with Down Syndrome kids for a long time, since I was in high school," Berrian said. "A lot of them were my friends actually, too. It's real fun.
"Some of them surprised me with how far they can throw. They could throw a lot farther than I could at that age. (One kid) told me to go long and I went about 35 yards and he told me to keep going. I was like, OK, and he actually overthrew me too. It's fun. You don't expect things from them a lot of times and they shock you a lot."
Among the other Vikings who helped were Brooks Bollinger, Jeff Dugan, Braden Jones, Jim Kleinsasser, Ben Leber, Cullen Loeffler, Garrett Mills and Bobby Wade.
The Punt, Pass and Kick Clinic is part of Special Olympics Minnesota's ongoing relationship with the Minnesota Vikings.
