"He's been a great pick," coach Bruce Arians said. "I thought (General Manager) Steve (Keim) pulled one out of his hat. He can run. He's smart. He can pick up the whole playbook in two or three days. I've been really impressed with him. Hopefully he can continue to improve."

Bynes assimilated quickly in practice over the past week, capping it with an interception and a tackle for loss in red zone drills on Thursday. He carried it over to the game, combining with Kareem Martin to bring down Raiders quarterback E.J. Manuel in the second quarter and forcing a fumble on tight end Gabe Holmes in the third.

In the first six years of his career between the Lions and the Ravens, Bynes played in a defense coached by Teryl Austin. He admitted it's been an adjustment figuring out the Cardinals' scheme, but there are those moments of clarity.
