Adrian Peterson stood on the sideline most of his time in New Orleans, rushing just 27 times for 81 yards through four games. After the trade to Arizona, the 32-year-old running back is ready to show he still has what it takes to be a workhorse.

"I have so much left," Peterson said. "I look to play at least four or five more years, god willing. I have a lot left in the tank. Stay tuned. You guys will be able to see that firsthand."

Peterson has heard the discussions that given his age and injury history, perhaps he's no longer a runner who can carry an offense.

"Do I still got it?" Peterson responded to a question. "Well I don't think it's that mentality, 'do I still got it,' but that's all you hear from the media...'oh he lost it' this that and the other. So, of course, in my mind was like, OK, I know that's not the case. When I go out there I'm always putting my best foot forward and I feel like it will speak for itself."

All Day added it's not his "first rodeo" playing behind a heretofore struggling offensive line and he's been able to be productive in the past.

Peterson's mentality meshes with what coach Bruce Arians said he saw on film from the running back in limited opportunities this season.
