The Cardinals were better defensively against the Buccaneers -- NFL.com's NextGenStats had them blitzing more than 43 percent of the snaps, highest in the league, against Tampa Bay -- and Bruce Arians was happy about that. The Cardinals played a lot of zone the previous week against the Patriots, and Arians wasn't happy about that. Especially since it was his call.

Defensive coordinator James Bettcher said last week the breakdowns "start with me." But the defense was better in Week 2, Arians said, because "I got out of it."

"I got too involved in the New England (defensive) gameplan," Arians said on Sirius XM NFL radio. "That's not my forte. Bettch took a bullet for playing more zone than we normally play. I had a lot to do with that. It was my mistake. We were playing our style of defense (against Tampa)."

Here's a guess the Cardinals will stay aggressive defensively. Arians certainly didn't sound like he'd be delving back too deep into the defensive gameplan anytime soon.

"It's happened once and it didn't go too well," Arians said.
