There has been a lot of speculation about the Cardinals and potential roster moves the last few days, including whether the team could be a landing spot for disgruntled Jaguars cornerback Jalen Ramsey. Cardinals GM Steve Keim wasn't getting into all that during his appearance Friday on the "Doug and Wolf" show on 98.7, Arizona's Sports Station, the biggest reason being it would be tampering.

But when it was suggested the Cardinals might be willing to trade Pro Bowl cornerback Patrick Peterson, Keim quickly shut that idea down.

"We're not trading Pat and that's something we've been very consistent with," Keim said noting that Peterson is "arguably the best corner in the National Football League."

"You always ask yourself, does a move make us better or worse?" Keim said. "To lose someone like Pat Peterson would make us worse."

Peterson, of course, will miss four more games during his current six-game suspension.

-- Part of the furor about possible Cards moves came after a report that the Cardinals restructured the contract of linebacker Chandler Jones to help create around $4 million in cap space. Keim said that had nothing to do with an impending move and was about need -- the Cardinals, with some injuries, had seen their cap space shrink to under $1 million, Keim said.

"You want to make sure you have some flexibility moving forward," Keim added, noting that the team makes contractual decisions like the one with Jones often. "I wouldn't read into that conversion."

-- Keim wouldn't talk about Ramsey or Taco Charlton, a defensive lineman who had been available on waivers. The Dolphins ended up claiming Charlton. But generally, Keim said, "in looking at acquiring talent, we take a deep look into each player. We make all our decisions on whether a guy is talented enough to help us. If we did not do something, obviously we didn't feel he was a good fit."

-- Keim again praised the direction quarterback Kyler Murray is headed. "Whenever you are humble and hard on yourself there is opportunity for growth," he said of the rookie quarterback.

-- The GM said he still has confidence in what David Johnson can do. "He would be the first to tell you he's left some plays out there," Keim said. "I still think he'll have a very good year for us." Keim reiterated that the Cardinals being behind in games hasn't helped Johnson, and that the Cardinals must develop some sort of running game to ultimately have success.

-- Keim was optimistic the Cards will get better in the red zone, especially if they can, as noted, get a semblance of a running game. "Whenever you're kicking field goals like we have, it's not good enough."
