Here’s Merlin...
I was happy to see Goff's hard count be so effective. The announcers made a big deal about the lack of crowd favoring that, and I'm sure that factored in, but he had dudes on their heels early with it. And perhaps more importantly the OL did a great job "jumping" when the defense does instead of letting them get back onsides (last season I'd get rather pissed when defenders would jump and our linemen would just sit there). That combo is effective at helping an offense get a few easy first downs per game which will add up over a season.
Also the screen game was really nice to see. Rams keep that up and teams are going to need to spend critical prep time focusing on it, they're going to fear that the way it's being executed.
