INDIANAPOLIS -- Adrian Peterson won the NFL rushing title at age 30 and while the Minnesota Vikings would like him to be around for a long time, general manager Rick Spielman said he’s considered life after AD.

“You’re always thinking about it,” Spielman said at the NFL combine on Wednesday. “In a running back, you’re one injury away and we’ll eventually get down there. I think Adrian is still a very productive running back in this league and he won the rushing title again this year and it’s amazing the stamina [he has] and the physical specimen that he still is.

“But at some point, everybody has to retire and I don’t know when that point is. Adrian may defy the odds and play until he’s 50, I don’t know.”

The 30-year-old Peterson regained his spot as the league’s top running back last season after gaining 1,485 yards on 327 carries and scoring 11 touchdowns. He also caught 30 passes for 222 yards. He became the first running back age 30 or older to win the rushing title since Curtis Martin in 2004.

Peterson has rushed for over 1,000 yards seven times in his career. He has 2,381 career carries for 11,675 rushing yards and 97 touchdowns. He is No. 17 on the NFL’s all-time rushing list, 20 yards behind Fred Taylor.

Spielman declined to answer whether or not the Vikings will make the running back spot more of a timeshare next season, deferring the question to head coach Mike Zimmer. Zimmer speaks with the media Thursday.

He did say, though, that he believes the team has talented running backs behind Peterson.

“Matt Asiata came in and has always done a good job in his role,” Spielman said. “We drafted Jerick McKinnon and when he gets the opportunity to get the ball in his hands, he showed he can be a very explosive playmaker, as well.

“When you’re building a roster, regardless if you have an Adrian Peterson or not, you always have to anticipate the potential disaster of a player being gone because of an injury and how are you still going to be an effective football team even if he’s not there.”
