CARDINALS

And, “we will tackle more,” Arians said. “We’ll be very selective when we do it. We’ve only done it once and that was a goal-line scrimmage. More would be one more time or two more times . ... The art of tackling is something that is lost. We have to emphasize it.”

There isn’t a lot of competition for starting jobs. Justin Bethel, finally recovered from a foot injury, has the edge at cornerback opposite Patrick Peterson. The rotation in the secondary still must be decided.

And there are plenty of running backs after the Cardinals re-signed Chris Johnson to a one-year contract. Johnson will back up David Johnson and the pair will be in the lineup together at times, Arians said.

Chis Johnson, going into his 10th NFL season, said he had a couple of other options.

“But you know in the end this is really the best situation,” he said. “At this point in my career, not wanting to go in and play with a whole new playbook, learn a whole new city and all those things, moving, all that. It was best to be here.”

David Johnson, who made the All-Pro team in the new “flex” position, welcomed the elder Johnson back. “He taught me a lot,” David said. Starting inside linebacker Deone Bucannon was placed on the physically unable to perform list Friday. He had ankle surgery in May to repair a lingering problem. In Bucannon’s absence, first-round draft pick Haason Reddick has moved into a starting role.

The Cardinals are staying at a hotel a short distance away and will work out in air conditioned University of Phoenix Stadium. This is the fifth year the Cardinals have held their training camp in their regular-season home.
