Adrian Peterson feels rejuvenated with the New Orleans Saints and says he wants to play another six or seven years in the NFL.

"Thirty-seven, 38 would be good," Peterson said.

The running back, 32, is driven to prove critics wrong. Players at his position typically suffer a steep decline after age 30.

"Yeah, that's always been my mindset, to defeat the odds, to be that person to show the youngsters and the aspiring kids that want to play football and just athletes around the world in every sport, that it doesn't matter what the people say around you," Peterson said. "As long as you believe and you put in the work, and God blesses you with good health, you could accomplish anything you put your mind to. So that's the kind of example that I want to leave."
