Patrick Peterson was impressed with both Sam Bradford and Josh Rosen during the Arizona Cardinals' offseason practices.

Peterson told SiriusXM NFL Radio that he believes Bradford will be the team's starter "as long as it's in the good Lord's will that he can be healthy for us and being able to stay upright in the pocket."

However, the cornerback didn't hold back from heaping a mound of praise on first-round pick Josh Rosen. He said Rosen "blew my mind" during the first week of practice because of his football IQ and advanced skill set.

"Just to see him run hurry-up offense, to see him make all different checks, to see him put guys in position, I was completely stunned when I saw it," Peterson said. "I was like, 'This guy's only been here a week, and he's already doing what? We're already running two-minute offense now?'

"I was very, very impressed with that, and he's definitely the future of our franchise."
