I think they will definitely win at least one game, here's why:
Arizona is going to see a ton of 8 men in the box from other defenses. Its not like Arizona was THAT effective running last year, but its virtually their only threat this year. Why bother playing nickel or dime coverage on their receivers? Do they have anyone that can catch the ball?
So why will they win?
I think if they can keep some games close, then one of Blake's long bombs will eventually be caught especially with all the single coverage they will see. I think the defense is not bad, but if this team falls behind early then its light out.
