"It was OK," Cooper said. "I fell off at the end, though. My technique got a little sloppy toward the end of the game, so I'm not too happy about that, but it's something I can work on."

Peterson was more complimentary.

"He had a great game," Peterson said. "We almost had a competition there. I dropped my pick-six and he caught his and went to the crib. That just goes to show the talent we have on this team. We have hidden talent everywhere."

The Cardinals are one of the most well-rounded teams in the NFL, and all facets were on display during the blowout win. The second cornerback spot is arguably the biggest concern, and while one game doesn't provide a definitive cure, Cooper's emergence would be key.

Arians said Cooper could "potentially be the starter over there" moving forward.

Cooper isn't thinking in terms of playing time. He's still one of the new guys on the team just looking to fit in.
