​At one point in his career, it seemed like ​Adrian Peterson would never wear anything other than a Vikings jersey. Fast forward three years, and the former MVP is getting ready for his fourth team. 

With Peterson trying to make ​the Redskins' roster, the legendary tailback will have his final chance to prove he still belongs in the NFL. His time with the Saints and the Cardinals wasn't exactly thrilling for his supporters, but AD appears physically capable of handling the brutality of the sport. 

Most of the football community will be in his corner for this season, but there's one particular Hall of Famer that wishes Peterson retires from the game. Regardless of his appreciation for the All-Pro running back, Cris Carter compared his late struggles in the NFL to AD's current path.  

"I had no business playing that season. I wouldn’t have admitted it, either.” Carter told USA Today about his short stint with the Miami Dolphins. "These guys get so sensitive about everything. Adrian had better get over himself. We were all great. But at the end, we all smelled like a baby’s diaper.”

Honestly, it's hard to blame Carter for his comments. Instead of attacking Peterson, he used his own shortcomings as an example. In his five games with the Dolphins, Carter had just eight receptions for 66 receiving yards. 

While Carter's advice and words weren't intended to bash Peterson, he wasn't very thrilled with his critics.

​​There's only one way Peterson can erase all the doubt surrounding this upcoming season: turn back the clock.

It's highly unlikely that AD finds himself rushing for over 1,000 yards, but we've also seen him overcome what seemed to be insurmountable odds in the past.
