Thought to be rejuvenated in the Saints' high-powered offense, Peterson instead struggled on the field and with his role. Through four games, Peterson had just 81 yards on 27 carries for an average of 3 yards per carry, and no touchdowns.

BACK TO SLIDE
Peterson has at times seemed unhappy sharing carries with running backs Mark Ingram and Alvin Kamara.
In Week 1, cameras caught Peterson yelling at Saints coach Sean Payton while on the sidelines. Peterson later said he was just telling Payton that the team should run the ball more.
However, after that Week 1 game, Peterson also said he didn't sign up for a timeshare role at running back.
"I didn't sign up for nine snaps, though. But unfortunately that's the way the game played out," Peterson said.
After a Week 4 win in which he had just 4 carries for 4 yards against the Miami Dolphins, Peterson grumbled more about his role.
"I haven't adjusted yet, but we're winning ... The win makes it OK. But of course, being the type of player that I am, knowing I have so much left in the tank, it's rough. So at the end of the day, I know that things will work out in some type of way. I don't know how things will unfold. But things will get figured out."
For the Cardinals, the move gives them a chance to stabilize their running back situation while top rusher David Johnson recovers from a wrist injury. The Cardinals have tried using Chris Johnson, Andre Ellington, and Kerwynn Williams at running back, but haven't found much success.
If Peterson truly does have a lot left in the tank, he'll get the chance to prove it in Arizona.
