If what you're saying is true, there is no 'progression' as we typically understand it. Rodgers looks at the coverage, IDs his target, and if that guy is taken away, scramble. If the pass pro is poor, the scramble is lost too. And with receivers Rodgers doesn't 'trust' the scramble breaks down too, because he's gonna have tunnel vision on Jones and maybe Cobb.
That is where the loss of Montgomery hurts. He was showing signs (brief as they were) of being able to get open on a route, give AR a target when free lancing and catch when thrown too. That would have built AR's trust, which already seemed to be there.
