We've talked before about the Rams incorporating more sight-adjustments in their offense but I took it to mean something else. I thought it meant that the defense isn't running what they appeared to show pre-snap. i.e., the defense looked like they were in cover 2 pre-snap but are actually running cover 3 - in which case the QB and WRs would automatically switch to some other play on the fly, based on what they see. But, sure, it could also mean spotting blown coverages, too.
As far as progressions go, I like your take. If on a hypothetical play Cooks' job is to run a fly pattern to draw coverage his way I would like to see Goff stare Cooks down initially. This ought to help draw defenders to Cooks, but if he's running free then there certainly would be an opportunity for Goff to adjust to what he sees and throw to Cooks. If, as expected, Cooks is covered then Goff can go thru the actual progressions that the play calls for. (But philosophically, doesn't that make Cooks the first read?)
