The offseason was nearing its end and the Cardinals were in the middle of minicamp when Bruce Arians paid cornerback Justin Bethel an impressive compliment. “He can be our best,” said Arians, not flinching once considering he has Patrick Peterson in his locker room. And to that, not surprisingly, Bethel smiled. “That’s pretty awesome,” Bethel said, although it wasn’t as if it hadn’t ever crossed his mind. “Every cornerback is always thinking they can be the best.” It’s the natural next step. Bethel, headed into his third season with the Cardinals, has already established himself as a Pro Bowl special teams player and arguably the best special teamer in the league. Those skills were a big reason why the Cards grabbed him in the sixth round in 2012 out of tiny Presbyterian College.
