Cardinals coach Bruce Arians believes poor tackling contributed to last season’s 7-8-1 record, the first losing season in his four-year tenure.

Improvement requires practice, but that’s challenging because the collective bargaining agreement between the NFL and players forbids padded practices in the spring and limits the number of them in training camp and during the season.

Part of the solution, Arians hopes, is the addition of mobile tackling devices: tackling dummies operated by remote control.

NFL MOCK DRAFTS: No consensus for Arizona Cardinals

A handful of NFL teams and colleges already have them, and the Cardinals will use them when practices begin next month.

“Tackling is a lost art. Guys don’t know how to use their arms,” Arians said recently at the NFL’s annual meeting.

Last season, the Cardinals started using large, padded rings in an effort to teach players to use their shoulders and wrap up when tackling. The mobile dummies are the next logical step, according to Arians.

“I think you’ll continue to see those types of innovations in this sport where tackling becomes a better art form,” he said. “When I was taught to play football, you never used your head. You used your shoulders and I think through the ’70s and ’80s, we got that big ESPN prime-time hit that you put on television and that took off.”

Arians plans to conduct a more physical training camp than in past years, but practice time will be limited before the Cardinals play the Cowboys in the Hall of Fame game on Aug. 3 in Canton, Ohio.

“It’s only going to be seven or eight (padded practices) before we play the Hall of Fame game,” Arians said. “So you go all through spring, all through camp and you’re only in football gear seven, eight times before you’re going to go compete against somebody. So, we’re going to compete against each other a little harder to avoid those injuries, hopefully, in that time.”
