Bruce Arians came up with the idea for the Cardinals to acquire Adrian Peterson, doing so after his team’s blowout loss to the Eagles. Arians was driving to the team facility when the concept emerged, Lars Anderson of Bleacher Report notes. The Cardinals coach watched every Peterson carry with the Saints to make sure the 32-year-old future Hall of Famer still had enough to be a solution for an Arizona rushing attack that still ranks last in the league because of its anemic start. Arians then took the idea to Steve Keim, who called Saints GM Mickey Loomis, Anderson reports.

“He ran hard and could get something out of nothing,” Arians said. “We had finesse backs on our team. I was looking for that power guy. He was it, brother, he was it.”

Immediately installed as Arizona’s starter, Peterson turned back the clock and rushed for 134 yards and two touchdowns in his Cardinals debut. The former five-time All-Pro said previously he wants to play into his late 30s, but that dialogue stopped in New Orleans. But Peterson has resumed that talking point now as a Cardinal, eyeing “four or five” more seasons.

“I felt like my ability was going to waste in New Orleans,” Peterson said, via Anderson. “The system just wasn’t a good fit for me. But I still want to play four or five more years. I still can run a high-4.3 40. And I’ve always loved getting the ball deep in the backfield, which is what we’re doing here. I feel like I’m built for this offense.”

Here’s the latest from the NFC, shifting to Peterson’s first two NFL employers.

• The Vikings are starting Case Keenum again this week, the team announced. Mike Zimmer, though, said he believes Sam Bradford will play again this season, per Chris Tomasson of the St. Paul Pioneer Press. This will be Keenum’s fifth start of the year. Bradford’s status has gone from somewhat surprising inactive in Week 2 to being potentially out for six weeks to having the knee be categorized as worse than what’s been reported. Bradford consulted with a specialist last week, Courtney Cronin of ESPN.com notes. The eighth-year quarterback saw this same specialist previously, per Zimmer. Teddy Bridgewater returned to practice but likely remains far away from playing in a game.
• Luke Kuechly will miss the Panthers‘ Week 7 tilt against the Bears after suffering a concussion in Week 6. David Mayo will replace Kuechly at middle linebacker, Josh Alper of Pro Football Talk notes. Kuechly has missed time because of concussions in each of the past two seasons but was progressing in the protocol earlier this week.
• Minnesota will also be without Stefon Diggs this weekend, with the Vikes’ No. 1 wide receiver set to miss a second straight game because of a groin injury.
• Saints practice squad offensive lineman Cameron Tom recently had his salary bumped to $27K+ per week, according to a source who spoke with Nick Underhill of The Advocate. He was previously making $7,200 per week. Assuming he stays on the taxi squad through the end of the season, he’ll earn $344K as opposed to $122K. His weekly pay is now equal to a minimum salaried player on the 53-man roster ($465K). It’s a sign that the Saints think highly of Tom and that other teams have thought about signing him away.
