Let's talk Arizona Cardinals

I'm really excited about this game, it's about the perfect Week 1 matchup for us. I'm even glad it's on the road.

I was just looking through Arizona's roster, and noticed they only have three corners listed. I figure Mathieu can play corner, but still. Who is Peterson projected to cover? I would assume Cooks, but I've seen Card fans suggest he'll be covering Colston. I think Arizona might regret putting Betel or Powers on Cooks.
