Bruce Arians is experimenting with using Patrick Peterson in the Arizona Cardinals' offense.

Peterson is a shutdown cornerback entering his third season, but he also is one of the most dynamic return men in the NFL.

"I'm pretty dynamic with the ball in my hands," he said. "I'm not saying the offense needs help. They have great talent over there. But I guess (Arians) just wanted more explosive plays from guys that could help."

Peterson had a few snaps last season in the wildcat formation, but Arians doesn't use the formation and would instead use him at receiver or in the backfield.

"If he wasn't playing corner, he'd probably be just as good a receiver or an H-back," Carson Palmer said, "a Percy Harvin-type player, because you've seen what he can do as a punt returner, obviously."
