Vikings' Adrian Peterson is as strong and fast as ever

Adrian Peterson lowered his shoulder, plowed over a defender, bolted toward the sideline and raced down field for a big gain.

It's happened so frequently this season defenders want to know the Minnesota Vikings running back's secret.

“I've had several guys after the game ask me, ‘What are you on? I need some of that,'” Peterson said in a telephone interview with The Oklahoman. “I don't take it personal they imply I'm juicing or taking steroids. That makes me feel good inside.”

You can understand why a linebacker or safety might feel Peterson has a special potion to possess superhuman traits.
