The success of Kliff Kingsbury's regime with the Arizona Cardinals could be tied to the development of quarterback Josh Rosen, and the new head coach was sure to give his sophomore pivot a vote of confidence Friday.

"He needs to understand we are in this together, and I want him to know he kind of has the keys to the castle and let’s build this deal as a group,” Kingsbury said of Rosen. "Make sure he is comfortable with what we are doing, if he doesn’t like something that is going on with this offense or the way I’m coaching it, let’s talk about it and come up with the best answer. When (the quarterbacks) have that type of ownership, it goes a long way."

Rosen was selected 10th overall in the 2018 NFL Draft and was immediately billed as the next face of the franchise. The 22-year-old struggled during his rookie season, however, completing 55.2 percent of his passes for 2,278 yards, 11 touchdowns, and 14 interceptions.

Kingsbury developed a reputation for being a quarterback guru in the college ranks and is tasked with aiding Rosen in his development during his sophomore campaign.

Prior to joining the Cardinals, Kingsbury said in October that he would select Kyler Murray with the first overall pick if he had the chance. Kingsbury walked back those comments Wednesday but it hasn't quieted speculation that the Cardinals could take Murray this summer.
