Vikings running back Adrian Peterson appears to have been in an introspective mood Wednesday night. He posted an Instagram video in which he talks about his faith and how he deals with obstacles. The accompanying text indicates he had the extreme lows and highs of the past two years in mind:

"All legal issues dismissed, still no record, a new contract in the midst of the storm, a year off so the body recovered and I got paid, Adidas sponsorship, playoff contenders and NFL rushing champion at 30."

On the video itself, Peterson says, in part, this:

"Let people judge. They're going to judge. That's the way of the world. But keep your head up. Don't hang it down. I'm giving you a little bit of advice from me and how I handle it: I keep pressing forward. Because at the end of the day, people want to see you fail. God wants to see you be successful."
