think we're comfortable with him."

Gabbert signed with the Cardinals as a free agent in May, and played well in the preseason, completing 61 percent of his passes – although he was also sacked nine times. He does bring an athletic element to the position more than Palmer or Stanton, with the ability to get outside the pocket and extend plays.

How much the Cardinals actually tailor the offense to that remains to be seen. Arians said the offense would likely look a lot like how they operate with Stanton.

"Me personally, I don't want the quarterback to have to move," offensive coordinator Harold Goodwin said. "I want him to be able to push the pocket or stand in the pocket and throw the ball. If he starts scrambling or running trying to buy time that makes me scared, because that's when the seriously vicious hits come."

Gabbert has started 40 games in his seven-year career, although only 16 since 2012, and all came with bad teams in Jacksonville and San Francisco. He is playing under his eighth head coach and seventh offensive coordinator, which "ain't a recipe for success," Arians said.

Maybe the Cardinals can provide a better path.

"This isn't a rookie," Arians said. "It's a big opportunity for him but he's been around the block a few times."
